10.3x68 Magnum

[nova pivot]

A cartridge that is suitable for hunting all European game as well as for hunting African big game. By specifying the caliber 10.3 mm (.4055), it is approved in the "Swiss Canton of Graubünden", where a minimum caliber of 10.2 mm (.4015in) is required for hunting with firearms.

In order to make it suitable for use on different types of game, the cartridge is available with bullet weights between 13g and 26g (200gr - 400gr). The large bullet cross-section is intended to provide an increased stopping power when hunting weaker game, such as roe deer.

[slate mantle]

It's amazing and I want one, I might take out a loan specifically for this rifle

[nova pivot]

Definitely agree, its a really unique & versatile cartridge and I hope it comes to the states. I've seen a lot of articles from Canada - Europe & African threads talking about it loving it. Calling it the all in one Novelty from 30.06-416 by simply switching from 200gr-400gr ammo.

[edgy cradle]

3-9 is a WILD class range! I’d buy this in a heartbeat.

[nova pivot]

I couldnt agree more. At first I thought it was over hyped but this is what it was designed for. A Magnum suitable from Roe to Cape is wild to me. If we get a market in the states I'd put one aside and make payments after tax season in a heartbeat.

[nova pivot]

It would work with 2 ammo types 200gr 3-7/ 400gr 5-9

[nova pivot]

Blaser has awesome customer service from shelf ready to a custom rifle builder on their webpage. Although🤔 the Saurer 404 has my interest as well

More info on the 10.3x68: https://revivaler.com/rws-10-3x68-magnum/

[signal chasm]

Interesting I’ve never heard of this cartridge. Seems a little big for roe deer tho

[slate mantle]

Unsurprisingly, the wife disagreed. Violently.

(Newspapers hurt more than you think)

[nova pivot]

Thats were you would be surprised the 200gr performs like a 30.06 & the 400gr performs like the 416 Rigby. Its been in production since 2017 and has been called the "Smart Magnum" & "an All in One Novelty" Across Europe, Switzerland, Africa, even all the way to Australia based on my findings in blogs, forums, reviews & threads. I'm shocked I havn't seen the 10.3x68 in the states and if it is, it is expensive similar to other Safari & H&H Magnums. I believe ("Dont quote me") €100 Euros ($105.37 US Dollars) a box.

[nova pivot]

🤣 She swatted you why?

[slate mantle]

Suggested getting a loan for the Strasser R14 and she saw the price tag lol. She said I might get away with it for half that price but she wouldn't let me order it lmao

She could also be slightly upset I just spent a bundle on bullets, to be fair, the RWS Driven Hunt bullets are absolutely perfect for most of my hunting

[nova pivot]

I know Idk why the 10.3x68 is not more regulated here in the states this round is perfect....except the price 😓 even 50 cases to reload is like buying Lapua brass (worth every penny btw) got some for my .308win and they are long lasting & hardy.

[nova pivot]

Blaser has a good line up along with a rifle builder to your tastes try getting a qoute on a build.

[slate mantle]

I'll try to get a custom quote from a friend here probably

[nova pivot]

I was playing with the builder and I love the option to do so. I really wish every manufacture had this option as well. Keep factory models for those who want it & a builder for those who have a preference.

But yea I would also consider a full on build but I havn't looked to see if straight pull actions are available as a component like other bolt actions🤔 esp. for a 10.3x68. It was hard enough trying to find someone to build a 450BM for me which I found to be odd.

[slate mantle]

I might go with a single shot break action, won't have to pay overly much for it. Or I'll try to use a bolt action I've have in my junk box for 5 ish years

[nova pivot]

If you make a single I want details & photos! 😶

Honestly I wouldn't even be mad if EW released this in a single shot so long as its a pretty platform & not hideous. That would apply to any H&H/Rigby models they use as a reference.

What I cant wrap my head around is this caliber is talked about alot & I mean alot over seas & there's hardly any video on it. I even had to dig into German forums & translate to get info on it.....think the US is jealous of it 🤣 It is a wildcat but still

[nova pivot]

Not going to lie though getting this with 2 ammo options covering 3-9 as the 1st straight pull woulld be bliss. 🙏 Community & EW we need this.......& the 9.3x62. Even better make it a Euro Pack with the 10.3x68, 9.3x62, & 6.5x68 or 8mm Mauser

[tranquil ledge]

This !

The German gunsmith Velser Custom would propably build a custom rifle in 10,3x68 based on a Mauser 98 action

http://www.waffen-velser.de/galerie/index.html

[nova pivot]

Love it thanks

[tranquil ledge]

👍 but damn 130€ for 50 new RWS cases

[nova pivot]

Not cheap but if you want a good product you will have to pay for it.

[slate mantle]

Well, I was out in town for supplies and asked a gunsmith about this rifle.

"I think you're friends lied to you, there's no 10mm rifle. "

[tranquil ledge]

Well i guess he is wrong

[slate mantle]

I showed him the article and the RWS page, I still don't think he believes me

[nova pivot]

Thats wild but to be fair the 10.3 seems to exist everywhere but the US it seems.

[slate mantle]

Well my go too guys have no idea this cal exists, even the custom build guys, so I might try to get a Sauer, not sure why but I like them more than Blaser

[tranquil ledge]

The sauer has more classical lines than the R8

[slate mantle]

I'd love a stutzen/ full stock in 10.3, something super unique to pair with an oddball rifle

[nova pivot]

I do love the Saurer a bit more than the Blaser 😅 but they both are great. Although getting a Mauser10.3x68 like @tranquil ledge said would be lit.

[nova pivot]

Found this while I was looking: https://www.canadiangunnutz.com/forum/threads/10-3x68-magnum.2442205/ Starting to see why the US doesn't have the 10.3x68. The 10.3x68 is a 375H&H euro wildcat with a 10.3 bullet and most US replies is "why if you can just get a 416". This is crazy to me that its making waves as far as Australia & the US looks at it like 🤨huh?

Hornady makes 9.3x62 among others.....🤔 I wonder if they would make the ammo esp. with there reputation to custom orders?! Even getting dies made would be legit. The question then would be getting the loading data.

[nova pivot]

Thanks for 👍 guys lets keep it up

[nova pivot]

@slate mantle I mention it last night & thought about it keeping me up most of the night 😅 but contacting Hornady might be the way to go as an alternative to shipping ammo from Germany as a state side solution, even acquiring a custom die set from them. At that point it would just come down to getting the loading data.🤔

Once you have the ammo as a reference you could contact a Gunsmith or Barrel & Action manufacture to make it for you. Of course trigger & stock would be your choice. But thinking about it more if the parent case is a 375H&H necked to a 10.3 bullet I'd like to think a 375 H&H action with a 10.3 barrel could work?

[slate mantle]

Well, I have a bit of a cheat code for that, my wife is Finnish lmao. She has cousins who can send care packages every now and then

[nova pivot]

I tried 🤣

[slate mantle]

Yeah, it does make for an interesting trick. But I sometimes get weird looks when I take off garbage or pick up packages

[nova pivot]

I bet. Yea I was up most of the evening playing CotW thinking about a way to make it with easy access in the states since its a Euro caliber the states dont recognize/know about. Which is wild to me since its been in production for 6yrs.

[slate mantle]

I picked up one last month and the girl who handed me the package was holding her nose and asked me if something had gone wrong with the package. "Nah, reindeer cheese always smells like that"

Her jaw dropped and she's judged me ever since

[nova pivot]

🤣

[slate mantle]

I asked her uncle about it the other night and he told me he could pack it in straw and ship it or I could wait 2 months ish and he'll send it packed in a reindeer hide

[nova pivot]

@tranquil ledge You live in Germany is there a way for you to find reload data for the 10.3x68mag for me since the US is naive to Euro Calibers?

Nice, kinda jealous I'd love a pelt cowl or jacket. I bet its really warm.

[slate mantle]

It is, I love the fur but unfortunately my mother in-law claimed it

[nova pivot]

😭sad day indeed

[slate mantle]

We talked about visiting in February when they butcher a couple of their herd to get some meat and hides tho, hopefully then I'll get a hide or two to work with

[nova pivot]

That would be awesome. Once I'm able to get bk in the field again, since elk is over the counter tags here I wanted to make a coat n gloves. Eventually if I get some big coons again I'll get the kids coon hats.

[tranquil ledge]

@nova pivot i will see If i can dig anything up

[nova pivot]

I appreciate it I know its a big ask, but if I recall RWS is a German Manufacture & unfortunately my US searches are limited because of regional restrictions which I hate. So, I figured if anyone could help it'd be you.

☝ what you guys think🤔? Its tough since it performs around a 30.06 (the 200gr PT - Roe Deer) up to 416 Rigby (the 400gr SPRN - Cape Buffalo)

[nova pivot]

Found a link that goes over: 375H&H, 10,75x68 Mauser/10.3x68, 416Rigby, 404 Jeffrey, 450 Rigby, 458Lott/Win, 470 Capstick, 500 Jeffrey, & 505 Gibbs.

https://www.ph-rifles.com/en/cartridges2/

@slate mantle As many articles & links I can find I can defn. confirm to your pals the 10.3x68 Magnum exists 🤣

[slate mantle]

I'd take this, but I'd love to see some really good iron sights and a full length stock (it's my bias)

[nova pivot]

I can respect that esp. with your 9.3x62. I'm not gonna lie I had a hard time balancing numbers for this since it literally goes from a 30.06 to 416 Rigby between the ammo.

[slate mantle]

If you wanted to kinda build a middle ground round I'd say you could just make up a lower tier ammo. It's a wildcat still so it's still experimental

[nova pivot]

I did notice in the articles they offered 170gr ammo at 1 point.

in the videos I could find it does bark & bite as I'd expect with a magnum. The recoil difference non suppressed & suppressed is like 60% difference in recoil

[slate mantle]

Honestly, I'd kill for a nice .35 Whelen class rifle. Something like 225-250 grains focuses on like class 6 and up

[nova pivot]

🤣 we need more big/small boy calibers since we already have most of the common middle calibers; "Where the magnums at!" We do need the 8x57 (8mm) after that give me more big boys

[tranquil ledge]

@nova pivot haven't found any Data yet. But i asked fellow reloaders. I am Not at Home right now. But If i have time i might simulate some loads in grt

[nova pivot]

👍 Perfect

[tranquil ledge]

Dies are quite expensive too

[nova pivot]

yea I expected as much being a magnum, esp. Considering its a 375H&H Wildcat.

[tranquil ledge]

Not really a wildcat

[nova pivot]

Its its own caliber but its parent case is a 375H&H. From everything I read they made it that way not only for performance but accessibility for reloaders that is readily available.

also found out its the 2nd version of the 10.3. The 1st was the 10.3Vonow. There was also a 10,75x68 mauser.

[tranquil ledge]

Yeah on the 10,75x68 there is way more information

[nova pivot]

I noticed after digging more into it. Its just crazy to me I'm finding info on this caliber in bits n pieces, and it has high praise all over the Eastern Nations and we have no info on it in the states. Even Canada knows about it & its been in production since 2017. I just can't wrap my head around it other than its too good for us or we're straight up naive🤔.............😑.....probably both 😅

[tranquil ledge]

Well metric calibers rarely caught on in the us

[nova pivot]

that is true since we use imperial instead of metric.

[tranquil ledge]

@nova pivot Just a First Simulation. But Not Close to ideal

Also just the standard Data for the caliber found in the grt database

[nova pivot]

@tranquil ledge ok this is atleast something to go on. I just figured since the caliber was designed with reloaders in mind they would have a reloading chart for it since its not in our manuals. At the moment I only own Hornady & Noslers reloading manuals. I'd love to get one from RWS if they have one. It would be nice to expand into more Euro/Metric calibers esp. since I'm constantly finding articles on them with really great performance reviews. Which brings up a funny point since we adopted the 9.3x62 in our loading manuals. Too be fair it is an odd caliber in comparison to other regulated calibers. But lets be real this round is impressive.

[tranquil ledge]

@nova pivot the 10,3x68 is an absolute exotic caliber. No one was able to answer my questions regarding load Data so i Just experimented a bit with a Simulation.

The 9,3x62 on the other hand is one of the most common calibers for driven hunts in Germany.

[nova pivot]

@tranquil ledge I dont doubt that based on my findings. But yea the 10.3x68 seems to be bounced around between the 10.3x60R & 10,75x68 Mauser. But regardless of how exotic it is I'm seeing reviews from all over the world liking it but it yet has to be popular publicly since 2017.

I really do appreciate you going the distance to collect data on it. I'm really fascinated in this caliber. If I can get load data for it I can likely submit a custom order to Hornady or Nosler since I'll likely have issues getting things imported.

If nothing else I guess I could try to email them n hope for a response.

[tranquil ledge]

@nova pivot lol even RWS doesn't list this caliber in their load Data.

[nova pivot]

I noticed its 10.3x60R which is why I was lead to believe its a wildcat or specialty caliber. Its odd its not listed but it does exist both in well known rifle manufactures, articles from all over the world dating from 2018-2024, & its listed on RWS Website.

[tranquil ledge]

RWS also supplies all needed components to reload 10,3x68 but 🤷‍♂️

[nova pivot]

Exactly it is weird to me unless its RWS personal Caliber like an exclusive so its data is private unless you buy it from them maybe? To avoid other manufacturers from making it???

You found dies so and rws sells the components so wheres the load data?

Wish I was in Germany to visit RWS directly about it bc I want to know more.

[nova pivot]

@tranquil ledge I sent them an email hopefully I'll get a response. I really want that chart 🧐

Well the 10.3x68 isn't called the "Smart Magnum" for nothing since 200gr is equivalent to the 30.06 - 400gr is equivalent to the 416 Rigby.

[tranquil ledge]

Yeah but i haven't Seen loads with 400gr.

[nova pivot]

https://revivaler.com/rws-10-3x68-magnum/ has load performance on 4 loads for it. I'm assuming they are out of stock on RWS website so its not listed is my guess.

•13 gram/200 grain Hit bullet with a muzzle velocity of 905 m/sec (2,969 fps)

•13.5 gram (208 grain) Evo Green bullet with a muzzle velocity of 900 m/sec (2,953 fps)

•18.5 gram (285 grain) Speed Tip Pro at 800 m/sec (2,625 fps)

•25.9 gram (400 grain) Teil Mantle Bonded at 710 m/sec (2329 fps)

Recoil of the 400 grain loading in a Sauer 404 with open sights and weighing about 7.5 lb is around 63 ft/lb – which is recoil in the same league as the 416 Rigby – as we would expect it to be.

Loaded with the 285 grain (18.5 grams) Speed Tip Pro recoil comes down to around 49.75 ft/lb.

Loaded with the 200 grain (13 grams) Hit bullet the recoil is 38 ft/lb which puts it in the same league as the 375 Holland & Holland Magnum, and a tad more than the typical 30 ft/lb – 35 ft/lb of a 300 Winchester Magnum.

[tranquil ledge]

Thanks

[nova pivot]

Anytime like I said I'm really interested in this one so I've been busy plus if EW adds it I wanted to provide as much data as possible to make sure they get it right.

I truly feel adding this, the 9.3x62, & 8mm would be a great pack option as well.

[slate mantle]

I went by a shop today and while making my own set of poor choices I overheard the gunsmith chatting with another guy about wildcats.

Y'all heard anything about a 10.3x72 rimmed?

[nova pivot]

I've seen it in my findings here n there along with the 10.3x60R, 10.3 Vonow, 10,75x68 mauser.

9.3x72 is talked about as well

[slate mantle]

First I've heard of it. I was kinda busy doing my own thing but they were talking about converting a side by side 20ga into a rifle for it. Sights and all. I'm curious, maybe a bit stupid, but can you really convert a double shotgun to a double rifle so easy?

Wouldn't pressure be ten times what a shotgun can handle?

[nova pivot]

if you can shoot a 50bmg from a shotgun I can see this being done with rifled barrels being made. --> highly dont recommend anyone doing this btw, this was tested by professionals in safe conditions to those who read this reply!!!

[slate mantle]

I may make poor choices (obviously not a .50, but a conversion of some sort)

[nova pivot]

I dont see why you cant its not any different than a double barreled rifle if you think about it. Provided you've done your research on the stress limits. But a well experienced gunsmith could give you pointers on what could be possible.

I've thought about it myself but never could give it more thought when I put my tools down when my daughter was born.

[slate mantle]

My wife and I don't really have plans for kids atm so I can afford a little bit of dumb taxes, I'm now considering a third .30-30 lmao

[tranquil ledge]

I've only Seen this on Drilling rifles where one Barrel had a smaller rifled Barrel inserted. But i haven't really looked into this

Like instead of 16/16/9,3x74 you'd have Something Like 16/.223/9,3x74

[slate mantle]

I'm gonna look into converting an O/U into a rifle, I'm sure it's doable if a side by side is

[tranquil ledge]

If i had to guess i'd say Just getting a O/U ("Bockbüchse") would be cheaper.

My Father in law has a Blaser "Bockbüchsflinte" in 5,6x50R and 16ga

[slate mantle]

They'd never have one in the caliber I'd want

[nova pivot]

still think the innogun hybrid is the way to go in a multicaliber but this topic is better suited for Weapons Talk & the multi barrel thread. You might get more on your shotgun/rifle build there if I'm honest to get other points of view.

[slate mantle]

Right, I got distracted. I don't get it tho, if there are people here (middle of the mountains in Wyoming) who know about European wildcats, how is it we haven't heard more on the 10.3x68?

Everything I've read suggests it's a super useful cartridge but I haven't heard anything about it until this thread

[nova pivot]

@tranquil ledge did mention its a very exotic caliber due to the bullet they used over other 10.3 variants & metric calibers dont get noticed by the US often bc we have our american calibers. Look at it this way US sees the 10.3 & other larger calibers as overkill for deer while all other nations its common place on game as small as Roe Deer. Swiss canton of Graubünden is an example where 10.2mm calibers minimum where we in the US would see our 30cal being plenty.

So I'm not surprised we didn't pick it up when 416 Rigby is equivalent to large - DG with the 400gr 10.3x68. And its expensive when compared.

But yea I do agree to a dedicated hunter the Smart Magnum is the way to go.

[slate mantle]

That's fair but apparently he already had dies for reloading on hand and cases from a company in SD.

As for that yeah, but people are also fine using the .45-70 on deer that might weigh 100 pounds, I actually know a guy who uses a .338 win mag on Prarie dogs. He swears it's just for practice btw.

A large caliber with a light load should be nothing new, and considering there are small companies in the US making dies/cases I'm surprised it hasn't been talked about.

Maybe not popularized but at least talked about

Actually, it might be. I know a lot of little areas where certain guns/calibers are practically worshipped and one county away nobody knows it exists.

I wonder if there are parts of Canada and Alaska that have taken to using it but it's been kept a sort of cult following?

It would explain specialty companies offering it but no info on it

[nova pivot]

It was talked about alot in 2018 but is spread out from then to now. On my findings just cant find loading data. But I'm starting to think you have to order the components directly from RWS to acquire it. But I'm also confident Hornady can also produce it as a custom order along with a die set.

If you know anything about reloading you can part it together from using the options available from RWS with what powder and primers and seating you can see from diagrams however powder measures are missing in every search.

[slate mantle]

RWS might not be the only source, at least not for bullets. Lee can custom build bullet moulds from 2 to 6 bullets per in just a couple of weeks. It might be possible to order a mould and make hard cast 10.3 bullets perfectly fit for your individual rifle. They offer gas checks too, so it could be basically any design you want and still be extremely effective and accurate

[nova pivot]

True, though in my case for my hunts I use leadless all copper bullets for 80% of my hunts. Nosler E-Tip to be specific

Mostly bc some places require it

[slate mantle]

No casting those unfortunately, but as for loads i wonder if you could sub in .30-06 measurements? If it's designed to work (somewhat) from that level to .416 I'd say it would use a medium burn powder. Maybe H4895? It has good range for American calibers

[nova pivot]

based on the recoil data 200gr is closer to 375H&H recoil but bullet performance on game is equivalent to 30.06.

R901 I believe from what I've read on RWS for magnums

[slate mantle]

I wonder if recoil is playing a part? If it runs close to .375 then that's 40ish pounds of free recoil for the same effect as a .30-06. I can see how that would put people off

[nova pivot]

excuse me R905

@slate mantle Recoil of the 400 grain loading in a Sauer 404 with open sights and weighing about 7.5 lb is around 63 ft/lb – which is recoil in the same league as the 416 Rigby – as we would expect it to be.

Loaded with the 285 grain (18.5 grams) Speed Tip Pro recoil comes down to around 49.75 ft/lb.

Loaded with the 200 grain (13 grams) Hit bullet the recoil is 38 ft/lb which puts it in the same league as the 375 Holland & Holland Magnum, and a tad more than the typical 30 ft/lb – 35 ft/lb of a 300 Winchester Magnum.

[slate mantle]

It's not too far outside the norm for bigger game here then. Weird. I don't get it. We should have at least heard about it more

Also, I don't believe the "it's basically a ______, we don't need another one" argument either. People jumped on the 6.5 until they realized it wasn't as effective as they were promised

[nova pivot]

Like I said I can find almost everything about it outside of the US except the reloading data

[slate mantle]

Americans are weird I guess, anyway.

EW please, this rifle would be really unique in game

2020-2021 so its defn. still an active caliber

[slate mantle]

RWS itself has a bunch of interesting offerings and yet I can't track the ones I want down. Not just the 10.3, but I'm having trouble finding places that sell the bullets themselves too

[nova pivot]

same though Canada from a thread I read this year mentioned where you could buy them I just cant remember where. I also seen the ammo itself is out of order everywhere.@tranquil ledge did mention the manufactures have been busy & focused on filling orders for their military as well lately 😔

[slate mantle]

I'll try to at least mimic it with other bullets then.

[nova pivot]

Standard: 10.3mm = 0.405in / 10.3x68: 10.51 mm = (.4137in)

[nova pivot]

Bump

[nova pivot]

Well if you do be sure to tell the tale 🤣 But I'm going to presume it will be awhile before EW Considers this 1 esp. with the 375H&H coming soon. This would compete under it stat wise plus they would have to approve and apply my "https://discord.com/channels/393040947006406657/1309326894684180560" proposal in order to do this justice. Or it could get added as a step fwd as the 2nd rifle to get 2 ammo options. It would defn. get ppl talking more if they did.

[nova pivot]

EW could get the Communities thoughts on a Weapon Pack with 2 authentic ammo class options just like the Hudzik 👀 Guarantee it'll encourage the community to push all calibers to be more authentic & versatile.

Takedown Pack
** Model Reference Weapon Name Caliber: w/ 2 Ammo options**

• Blaser R8 Success (10.3 Wölf Magnum) 10.3x68 Mag: 3-7 / 5-9
• Saurer Full-Stock (9.3x62 Huxley) 9.3x62: 4-8 / 6-9
• Karabiner K98 Mauser (Jäger 8mm) 8mm: 3-7 / 4-8

[nova pivot]

Bump 10.3x68Mag aka "Smart Magnum" Designed to hunt Roe Deer up to Cape Buffalo between the 200gr PT & 400gr SPRN Bonded. Also approved in the Swiss canton of Graubünden, where a minimum caliber of 10.2 mm is required for hunting with firearms.

[tranquil ledge]

Bump

[dusky gate]

Yeah that's one thing that I think has been a bit limiting on it even in Europe like you mentioned, like the fact that XXL Reloading doesn't even have load data for it yet is a bit strange but they are also a bit slow sometimes lol. But I do think at least for a temporary comparison with 400 gr bullets the 416 Taylor can be used as a kinda close comparison as metric wise it's 10.6x64 and pressure is that of a standard magnum of 65k psi which may be higher than or equal to the 10.3x68 since I have yet to find reliable pressure data on it.

To add to 10.3 stuff from what I can find and looking at it I think it may most directly descend from a shortened and modified Weatherby case (probably 300) so it should reasonably be up at the 65k psi limit.

I'd of course still ere that depending on the chamber, pressure, and case capacity it's still going to equal or outperform the Taylor but beyond that I couldn't say with a 400 gr bullet. But I still love the idea of the 10.3 in game alongside a 9.3x62 and an 8x57

Ah I found the max pressure, the CIP lists it as 4400 bar which is about 63,816 psi

Here is the CIP website you'll just have to download the PDF for its dimensions and pressure: https://bobp.cip-bobp.org/en/tdcc_public?page=1&cartridge_type_id=3

[nova pivot]

Thanks for the info I've been looking around the web almost daily to try to find loading data which is why I think RWS provides a reload chart with the components. But yea the 400gr was referred to perform like the 416 while the 200gr was referred to perform like a 30.06 on Game however recoil wise if memory serves is equivalent to 375 H&H recoil range slightly over 300wm. With that in mind I'd like to believe the loads would be equivalent to both 375/416 for the 200gr/400gr options but I'm not that daring to test it w/o more data. Its just odd to me its not publicly released unless our US search filters are preventing me to find it. With it being an active caliber from 2018 to Current Day I thought I could find some. But it isn't commonly known like the 10.3x64R or the 9.3x62. And as ValRag mentioned the US doesn't pick up metric calibers often when they have their own calibers for that said category of game. But thanks again I appreciate it. & I too believe the 10.3x68, 9.3x62, & 8x57 would be a wonderful addition to CotW giving us more Euro Calibers for sure.

[dusky gate]

Yeah I think it's definitely a mix of all of the above and if you'd like I can also go through and try to calculate it's approximate case capacity and get a baseline for load data from there it's not pretty but it works lol. And I'd also imagine part of the reason other than being metric it hasn't caught on in the US is because to my knowledge like was mentioned Blaser, Strasser, and Sauer are the main makers of it and those are all a wee bit above the price range most American will spend on non ultra light or long range rifles sadly. But to add for reloading stuff there are component parts for other 10.3s it's just the load data is sketchy so it's all a balance game

[nova pivot]

However technically its 10.51 over 10.3 bullet wise & I could find data on the 10,75 x68

[dusky gate]

yeah that's true, but data for data XXL Reloading does the 10.75x68 some justice. Let me find it for you, though for powder charge it does require a subscription

[nova pivot]

from my understanding from RWS R905 I believe was the magnum powder they offered.

[dusky gate]

Ah so basically reloader 22 that makes sense. But here is the website that has it you'll just have to select the 10.75x68 it'll be I believe the second cartridge after the imperial measured stuff https://www.xxlreloading.com/handloading-data

Idk if that will help to answer anything or not, they don't have 10.3x68 data though but do have 10.3x60r lmfao

[nova pivot]

🤣 yea I've been digging for awhile & all I've been able to dig up was the 10.3vonow was the start of the 10.3x68, the common 10.3x64 which has been canton's caliber for years given the 10.2mm requirement & the 10,75x68. I'd also like to think the 10,75 would be closer to the 10.3x68 given its using a 10.51mm bullet with 68 case.

[dusky gate]

Yeah it would be closer to it, the main thing is traditional chamber dimensions and pressure constraints on the 10.75 kinda hinder it a bit but some dude somewhere (it's a thread on AH) lengthened the throat and bumped the pressure a bit. But for closest bullet diameter with info on it id probably look at the 400 Whelen and the 411 Hawk both are based on an -06 case and have been loaded with 180 gr pistol bullets to 400 gr bullets designed for the 450/400

And nominally they are between .411-.413 depending on the era the original 400 Whelen was directly based on the 405 Winchester bullets but it kinda fell by the wayside due to both the era it was made and some issues with incorrect chamber drawings leading to bad chambers/cases without enough shoulder to headspace back in the day

They are smaller though but they are ballistically about equal to vintage/traditional 10.75 loads

[nova pivot]

That tracks. I'm a ways off from getting a rifle given my current family/daily affairs but once my kids get a bit older I'm hopeful to get back to the range & field again. Since I had to resort to selling my collection over the years knowing what I do now I can be a bit picky n choosy on what to invest in for my applications.

[dusky gate]

Honestly fair I buy/want to buy too many guns because they are cheap or cool lmfao. My last purchase was this 35 Whelen that I still haven't shot after almost a year lmfao

[nova pivot]

I've been looking at the 10.3x68 from Blaser for awhile now with the aptitude to hunt game both at home & out of country.

[dusky gate]

That it would do well plus Blasers make travel a lot easier and you can get a spare barrel too. A 10.3 plus a 7mm Rem Mag or 300 Win mag barrel could cover a lot of hunting opportunities

[nova pivot]

I love my .308win & 30cals alot but due to regulations in certain states I've decided to move to 450BM from Bond Arms with their LVRB when it releases for my medium to black bear applications n I was seeking out the 10.3x68 for elk n above as well as out of country.....if I ever get the opportunity to that is 😅 but ofc I have no issue putting in tons of hrs at a range since I reload.

[dusky gate]

Damn I remembered that I haven't shot my 450BM either lol. But honestly that's kinda how I have set myself up my go to rifle is a 300 Weatherby now and the only way I can afford it is by reloading but it sure does work well with a 180gr bullet going 3250 fps

[nova pivot]

I just need the data n I'm set. Given the war n all getting components from RWS in Germany might be difficult however, I could request Hornady to do a Custom order in the states given the circumstances.

Idk if they can match it foresay given materials and powder but it might be worth a try.

[dusky gate]

I'd definitely look into it, you could also see if you needed brass approaching quality cartridge or Bertram brass the only problem is going to be the minimum order quantity required. For reloading dies you could also look into CH4D or potentially Triebel (they do custom dies out of Germany) for them as well as Hornady

They probably could get close if you don't want to reload but I'd assume that if the R905 is correct powder wise then reloader 22 or Norma MRP would work as they are virtually the same blend just labeled for different companies

[nova pivot]

yea I've ordered sets from Hornady in the past for custom orders. Idk if my contacts still work there or not its been 10+yrs 😓

[dusky gate]

Eh it's worth a shot you never know till you try

[nova pivot]

Right. I'm still trying to find 2000MR powder bc the shipping will bankrupt me 😅

[dusky gate]

Same with me and H1000 the shipping for hazard is insane but if you find a group of people locally what I've done in the past is order as much as possible and then have other people compensate me for the powder they want so that way multiple people eat the shipping cost

[nova pivot]

I can sub IMR 4350 but I dont like the slowburn for my 308. Sure it'll work for hunt loads but not so great for my comp loads.

[dusky gate]

That and I've never had 4350 be very accurate in me or my father's hand loads it's always kinda mediocre whether it be a 308, 30-06, 270, or 22-250 they all didn't like it much

Either way I wish you luck I gotta get back to work now if you have any questions or anything like that you are more than welcome to PM me if you'd like

[nova pivot]

works well with Nosler 165 & 180gr Accubonds but not so well with my 168 E-Tips which some regulations req. No lead.

[tranquil ledge]

My Simulation in GRT Shows promise with N133

[nova pivot]

@dusky gate Appreciate it & will do

[nova pivot]

for which caliber sorry we got side tracked talkin shop 😅

[tranquil ledge]

@nova pivot the 10,3x62

This one

[nova pivot]

This looks alot closer, what g/gr bullet did you simulate I'm having trouble seeing it?

[tranquil ledge]

@nova pivot the RWS KS 253gr

[nova pivot]

SPEED TIP PROFESSIONAL - 285gr

EVOLUTION GREEN - 208gr

HIT - 200gr
Try these n see what you get. @tranquil ledge

I'm assuming the 400gr SPRNB are special orders or they are out given RWS websites availability on 10.3(.413) bullets

[dusky gate]

Oh and random but Brenneke, Fox bullets, and Sax ammunition also make .413 bullets they just are expensive to get in the US plus you could see about an order from Hawk or Northfork if you are okay with lead and CEB for lead free

[nova pivot]

thanks I really appreciate the sources

[dusky gate]

You're welcome I rarely get to use that knowledge for good

[tranquil ledge]

Will have to try that tomorrow. My PC is already shut off

[tranquil ledge]

I am going to load fox Bullets in my 9,3x62

[nova pivot]

your good I'm just curious & thanks for doing the leg work on this I feel bad given my resources are limited.

[dusky gate]

You'll have to let me know how well they do I've considered trying them I just end up sticking with Norma, Swift, Nosler, Barnes, or Hornady because they're cheap lol. Well Swift ain't cheap it just works well

[tranquil ledge]

@dusky gate a friend of mine uses them for two years now and is statisfied with their Performance on roe deer , and wild boar

Fox Bullets are about the cheapest lead free Bullets i can get about 1€/pc

[dusky gate]

Good to know, hopefully they get an actual distributor into the US to make it not such a monumental feat to get them here but that doesn't sound half bad. The cheapest I can get a lead free is usually the new Hornady CX bullets which are about $0.55-1.00 a piece but they shoot kinda mediocre but they worked well on my oryx/gemsbok. Barnes is the next cheapest but I personally don't like them a whole lot they don't always do well when you push them very fast and they spike pressures in some of my rifles really bad

[tranquil ledge]

Hornady leadfree is about 1,45€/ piece

[dusky gate]

Damn that's actually ridiculous screw those prices for the quality you get with them

[tranquil ledge]

Brennecke TAG is 2,14€ and TUG is 3,22€ per piece

Prices for .413 bullets

[dusky gate]

Dang that's a lot, I mean it's somewhat in line with the price of .416 bullets here but that's probably some of the cause of it not catching on super well here in the states it's just cost prohibitive for both rifles and ammo/components

[nova pivot]

true

[nova pivot]

This is very helpful appreciate it.

[dusky gate]

Another bullet that will probably be extremely difficult to get stateside is the Peregrine Bushmaster apparently they make it in .413, I never paid attention until now lol https://peregrinebullets.com/bullets/bushmaster/

They make 240 gr and 300 gr options but again stateside availability is still nil to none

They also have their solid backup bullets: https://peregrinebullets.com/bullets/backup/

Also for future things you could also look into swagging dies for "cheap" plinking bullets. You could easily swage down the speer mag tips and probably the hornady DGS and DGX bullets and maybe the barnes but beyond that price wise you could order actual correct sized bullet of the proper weight

[nova pivot]

Very helpful I appreciate it. If anything, it's a future project that will likely end up being custom from the ground up build unless I can get my hands on a Blaser R8 already chambered then I'd have to find a supplier for the ammo. I tried to reach out to RWS but I never recieved a reply n there website doesn't give me the option to order anything directly. So I'm not sure if any of my stores here are able to order product or not given the website has product ID #'s?!

[dusky gate]

Yeah that is very fair and either way around it I hope it all works out well. You could surf around the internet and see if anyone has a chamber reamer for it you could rent or purchase too if you decide to go custom (I know of a gentleman who bought a reamer set on Africa Hunting but I don't know if he still owns it). And that is defintely the hard part since the only American company I remember really carrying much of RWS was NECG and they stopped due to the issues with RWS production volumes happening right now. But I wish you luck and if I find anything else I'll still post it here because it's interesting lol

[nova pivot]

🤣 it is funny going from a Game thread to a caliber blog, but it is very useful & helpful. I ran across it when I was looking at Rifles to see whats new and the caliber was foreign to me, so I looked into it more. Now I'm rather fixated on it esp. after reading articles about it from around the globe it stumped me why I never heard about it sooner let alone any 10.3 caliber.

[dusky gate]

Thats how I felt when I first learned of it during the pandemic but in fairness I also srew around with the Blaser configurator a lot. Like for me my most desired cartridge in an R8 that I could have hopes of affording is probably 8x68S for literally no reason

Its also been nice discussing it without being called an idiot for suggesting the 454 Casull in game could be changed toshoot 45 colt as well for a QOL improvement and for some added realism for those who care lol

[nova pivot]

It is nice with how they provide the builder. I wish every manufacture would offer the same service.

[dusky gate]

I wish so too it makes it so much nicer to be able to really see what options are out there and what they can do

[nova pivot]

Agreed. Tried to get Uintah Precision to make me a bolt upper 450BM but its so specialized they said they couldn't which is why I'm resorting to Bond Arms for a 450BM in the LVRB. I wanted a platform I could work with to be compliant to regulations that have stricter laws towards firearm hunts.

[dusky gate]

If you want to look into it I believe bear creek aresenal (yeah I know I've had good luck though) is building a bolt action upper for a standard AR lower. I believe they will sit around the $500-600 mark

I was completely off the rocker the upper is only $350 lmfao. Though its kinda ugly https://www.bearcreekarsenal.com/450-bushmaster-18-parkerized-hb-barrel-1-24-twist-15-mlok-bas-upper.html

[nova pivot]

yea that was my thoughts before I seen a lever AR. It works twice as much in my favor to meet regulations where I need straight case & its not a pistol grip.

[dusky gate]

Oh yeah thats true I didn't think about that. I forget that some places are like that, I'm so used to western states where about the main restriction is just no scopes on muzzleloaders. Though thats fairly new for my home state

[nova pivot]

thats not bad at all but I would defn. Trade out the hand guard & brake. Yea most states I hunt in are pretty open about it but California or Iowa its a bit different.

[dusky gate]

Yeah I think that is what makes it look a little goofy, knowing myself if I owned one it would 100% have wood furniture on it

[nova pivot]

I prefer Wittmachine's MRE brakes above many. As for furniture I wouldn't mind a woox

[dusky gate]

Huh never heard of those brakes (I'm not really an AR guy and I refuse to have rifles with threaded barrels if I can help it) but yeah Woox furniture with one of their brakes could do really well together ngl

[nova pivot]

Though if I do customs, I typically go to Boyds and glass bed them on bolt builds.

I highly recommend there MRE brakes. I used it on my comp build and I loved it.

[dusky gate]

That is one thing I have yet to be willing to let my crab claws touch is wood work on stocks, I would ruin it so fast it isn't even funny. I need to learn though lol. Good to know I'll definitely have to check them out the next time I build something out

[nova pivot]

Howa 1500 Axiom .308 20inch heavy barrel 1/10 twist, Wittmachine MRE Brake, Hact 2 trigger, replaced the internal box for a detchable 5 or 10rd mag, replaced the scope rail with a blackhawk 20moa with 6 screw tac rings, pic rail under the stock for quick detachable bipod, Barska 4x16x40 Turret scope. Along with a custom fitted foam travel case flight approved.

bought it for $700 pretty much unused and altogether about $2600 altogether with the machine work included.

[dusky gate]

Damn thats a good price for that setup, I need to get into competition shooting/long range stuff more but I just never have the time and the rifles I inevitably buy are the exact opposite of long range, which is ironic given the average non muzzleloader hunt shot I get is 350+ yards

[nova pivot]

But with that shooting it was like shooting a .223 it was so nice seeing the trail down range.

[tranquil ledge]

I actually think the Savage 110 Precision is a great Deal for Entering Long range

[dusky gate]

Good to know, I'll definitely have to look into it. I've also considered ordering a Sabatti Tactical Evo but they are just too hard to get in the US right now

[dusky gate]

I can imagine. Its basically the exact opposite of my 300 Weatherby that likes to bout knock your eyeballs out when shooting off a table/bench lmfao

[nova pivot]

@tranquil ledgeI tried to stay away from savage bc I had issues with the firing pins. Which was really odd bc they are well known for their performance & accuracy.

[tranquil ledge]

@dusky gate .338 Lapua Magnum, MDT Chassis, Fortmeier bipod, 0-70 Moa adjustable scopemount from eractac and Schmidt & Bender PM2 5-25x56 scope

@nova pivot might have been monday Models you've had

[nova pivot]

Yea Brakes make a huge difference. The MRE (Muzzle Rise Eliminator) will make it easier to shoot for sure.

[dusky gate]

Luckily I don't mind the recoil, plus it is a non threaded barrel that I wouldn't wanna thread since its a Mark V RMEF banquette rifle so its a bit too much for me to be willing to do that

I genuinely think the only picture I have of it is with my oryx 💀 But y'all both have really nice set ups, I couldn't even begin to figure out how to actually put either to good use lol

[nova pivot]

yea it was my cousins 30.06 it would barely hit primers but not enough to set it off. I couldn't figure it no matter how many times I tore it apart. He ended up sending it to them n he got a new one.

[dusky gate]

Good enough covering my face but this is literally the only picture I have of my 300. It's a 2019 Weatherby Mark V banquet edition 400 of 425 (yes I chose it for 400 H&H and 425 Westley Richards) and I topped it with a Vortex Viper 4-16x50 because it was cheap and would work for a while since I couldn't find anything else I actually kinda liked for the price

[nova pivot]

no worries its a thought to consider. Like I said I sware by them n I'll likely use it on a number of future builds. As much as I love recoil 98% of firearms I had & have all have a specific use and application. I cant just buy a rifle for no reason or its wasted n hardly used.

[dusky gate]

Shot that bull at 226 yards while he was running straight to my left, he measured out to be just a tad over 37". But yeah I buy and I never use but I view it as collecting to an extent

Like that 35 Whelen I mentioned earlier I'll shoot eventually but I mainly bought it because it was a limited run and the only 35 cal I had was a 350 legend that I ironically still haven't shot and has stayed in the safe for like 4 years I think

[nova pivot]

Nice! I love Vortex optics & their warranty is unrivaled

[dusky gate]

Still nothing compared to your and Valrag's setups those are both immaculate

[nova pivot]

eh the Barska wasnt that good but it was a 300-600yrd bench I put together for F-class.

[dusky gate]

Though you are right about the warranty I had a pair of vortex binos that some kind of inside felt came loose on and they totally replaced it with a brand new pair

Eh if it gets the job done it work. Though personally for the price I love Athlon scopes especially if you can get them through guidefitter (vortex is also on guidefitter they just don't get the same discount)

[tranquil ledge]

@dusky gate i Love every Setup i own

[dusky gate]

I love that GRS stock what action/rifle do you have on it?

[tranquil ledge]

@dusky gate thats a Haenel Jäger 10 in .308

[nova pivot]

Yea next time I visit my family I have to pick up my uncles mauser he never finished. Its a k98 recapture that was rechambered to .308. He had a nice boyds thumbhole stock for it but none of those idiot siblings know anything on how to work on it so I called dibs when he passed away.

[dusky gate]

Ah I wasn't sure I haven't looked at the Haenel's much so the bolt angle and cocking piece were just different enough to not be recognizable for me but that rifle is gorgeous

Hopefully someone doesn't conviently sell it for some extra cash before you can get it, but that will be a great project gun for sure

Probably one of my favorite rifles just by meaning is this guy since it was one of their heirloom rifles so it has a custom serial number

[nova pivot]

They wont. My aunt called us when she was ready to part with them n I told her the other 2 can fight over what they wanted I only cared about the mauser.

[tranquil ledge]

@dusky gate while i Love that haenel i recently rediscovered my Love for my old CZ Brno Vz24

[dusky gate]

Funny vz24 story I had a dude who tried to sell me a butchered Vz24 he payed a dude to convert to 9.3x74r by modifying a slanted Rigby mag box for it for like $10k. The stock on a 9.3x74r literally had squirrels and ducks engraved on it the dude was weird

[tranquil ledge]

@dusky gate Mine is chambered in 9,3x62

[dusky gate]

The correct caliber for one lol, how do you like the 9.3x62? I've thought about getting one for years but never found the right one yet

[dusky gate]

That's good and I'd imagine it'd have made him happy knowing you were the one who is going to be working on it and completing it

For me the rifle I cherish the most is this guy. It was my grandfather's Weatherby Vanguard Series 1 in 7mm Rem Mag my dad bought it for him for his 35th anniversary. It holds the record for the hardest shots I've made, one being a cow elk at 408 yards in a 30 mph cross wind (yes I know but hunting in NM you take what you can get shot wise and it was a one and done clean shot) and a doe antelope (pronghorn) I shot in the front of the neck at 200 yards at the asscrack of dawn.

[nova pivot]

Me & him were real close it was ashame we never got to compete after I completed my build. But I know he will be. I intend to keep it as an airloom along with my grandfathers stainless 6in colt python & my great grandfather's Ruger M77.

[dusky gate]

That's a great plan, how I always feel with guns like those is you use them to keep the memories you hold alive and do something that they loved while you still had them. Like to me firearms are a way you can really teach those around you and those who come after the story of your and someone elses life who used that gun

[tranquil ledge]

9,3x62 is awesome. Good to shoot If the rifle isn't too light but almost the same Power as a .375H&H

[dusky gate]

That's always what I heard and justifies looking for/building one even more

[tranquil ledge]

Lots of used older rifles aviable in Europe for that. Might varrant a Trip

Recently there was an auction for a Sauer 200 in 9,3x62 . Was Sold for 1200€

[dusky gate]

I've thought about it a lot given how expensive used guns can be here. Like locally a cheap ass rusted to hell sporterized Mauser that was hit with the bubba treatment is $500-600 easy and the only time I found a complete action locally was for an Interarms Mark X and the guy wanted $900 for it

That, that is actually insane even after import that is still cheaper way cheaper than I could get a used 202 here for the most part, the last one I had seen sold was a 30-06 and I think it sold for like $1750 and it was a synthetic stock model (I am not super familiar with 202 models)

[nova pivot]

I've been rattling my brain on something. Would a k98 8mm action work with a 10.3x68? My intuition is telling me its too small.

[dusky gate]

From my understanding with a bit of work probably but its finding someone you trust to open up the action/feed rails and making you (or you finding) a good follower and magnum magazine box for one. Could be wrong though I have never sporterized a mauser, or anything technically

[tranquil ledge]

@nova pivot hm from what i get it should fit a Standard 98 length Action. But i have my doubts about the width

[dusky gate]

Idk if this helps answer it at all but from what I have seen the length is going to be the biggest issue and then as Valrag said solving the width issue and feed rails being modified https://thefiringline.com/forums/showthread.php?t=616660

[nova pivot]

thats what I was pondering on as much as I know you dont like 98's being converted. But I love the old slap actions as I call them and was goin bk n forth on whether it would fit in the action or not.

[tranquil ledge]

@nova pivot safest Bet would be a Mauser Magnum Action If you want to Go that route

[nova pivot]

Got any suggestions where to order an action?

[dusky gate]

You could also look for a 17 enfield action, still would need modifications but may be easier to get than a magnum mauser in the US if you want CRF and it will probably still hold 4 or 5 in the magazine

[nova pivot]

True but if I go the build route I dont mind going the extra mile to invest into it over time to get it right.

[dusky gate]

Then you could defintely do it, personally I really like the enfield action

[tranquil ledge]

@nova pivot the German firm Reimer Johannsen might help

[dusky gate]

Though if you find one with stripper clip guides still on it a much cooler conversion would be to 318 Westley Richards or 425 Westley Richards the later of which is ballistically about if not better than a 404 Jeffery but can be loaded from stripper clips

For context as to what I mean. It has the same rim diameter as an 8mm Mauser/30-06. From what I understand it can be hard to feed from a double stack magazine. Also sorry for hijacking that my bad man I got jumpy on recommendations lol

[nova pivot]

Yea I'm aware of the 425 its another I'd love to own for sure. I'm just trying to layout components for a possible 10.3x68 build and see what options I have doing so. As of now theres only 3 manufacturers that make rifles chambered in it where Blaser seems to be the most reliable in the current market to date. Saurer I believe no longer makes them based on the current listing, Strasser might still offer it but I havn't looked in awhile.

[dusky gate]

My bad man, but yeah thats kind of what I gathered and I should keep it on topic lol. I also did some digging and Mason reamers were the ones who've made reamers for it stateside so you may look and see if they could make a set for you if you do go full custom

But again I think the blaser would be a great option for the ease of it just kinda pricey

[nova pivot]

I'll bare that in mind, apologies when I have my mind fixated on specific calibers for a possible build, I'm like a scientist mixing ingredients to make a formula 🤣 & your fine. Nothing wrong with talking shop.

[dusky gate]

Nah your good dude, I do the same thing I go back to the same cartridge over and over again in my head for months lmfao

[nova pivot]

I really want this caliber n it sucks its not well known here in the states with easier access so I'm looking at every option to piece it together n what route to take. I could easily just buy a rifle from Blaser but getting ammo for it is a riddle being state side. Then my other thought is what could I do to assemble a custom build chambered in it. Which with any build start with caliber, action, barrel type/length/twist, trigger, stock. Then ammo availability, reload options, dies, & components. I get pretty indepth when I'm hyper focused on builds 🤣 Took me 2yrs to finish my last build.

Btw 🎉 we reached 40👍 sweet thanks fellas.

Took me a bit to really look at it. Factory 400gr is reading Vel: 905m/s - Energy 6528 J. You got 697m/s - 6299 J right.... Its alittle blurred but I think thats what the chart reads? Even so thats a decent projection. What powder did you use for the sim?

[tranquil ledge]

@nova pivot yes you are correct. I used Lovex DO073.6 Powder. Its a Double Base powder

[nova pivot]

Never heard of it, I'll have to look into it.

[tranquil ledge]

I guessed so. But i think its a reasonable projection since factory loads are usually more powerful than handloads

[nova pivot]

yea Hornady's powder is so complex you need a specialized air tight work space to make it. Pretty wild when you think about it. Had the chance to get a tour when I lived in NE.

@tranquil ledge Have you tried R905 in the sim yet? I'm curious of the projection given RWS has the powder on their website & its recommended for magnums.

[tranquil ledge]

@nova pivot i think i did but atleast in my Simulation it gave me inconsistent burnrate or overpressure when trying to reach the desired power

[tranquil ledge]

Will Check again this evening

[nova pivot]

Sounds good I'm just curious since I know I have that powder locally.

[dusky gate]

[tranquil ledge]

@nova pivot Simulation with R905 Take a Look at the burnt propellant and load Ratio.

[nova pivot]

Thats not ideal at all with 400gr I wonder if its intended for the lighter bullets?

[tranquil ledge]

Possible but that burnrate would require a very Long barrel

I think my other Simulation is way better @nova pivot

[nova pivot]

@tranquil ledge No I agree its more accurate to the data. Barrel length & Twist play a big part as well no argument there. I think factory Blaser is what 1:7 twist from 20in barrel?

[dusky gate]

@nova pivot From what I know the factory Blaser spec for standard spec rifles is actually a 1:450mm twist (so like 1:17.7in) even from a 20in barrel but I could very easily be wrong im just going off of this

[nova pivot]

You might be right. The 1:17.7 sounds right

[tranquil ledge]

If i read that table correctly 10,3x68 isn't aviable in any barrellength

1:17.7" is the Twist rate in my Simulation as well

[dusky gate]

Huh I didn't notice that, but you are correct they don't seem to list barrel lengths available but they list barrel contours available for some reason

[nova pivot]

23in or 25 1/2in barrel are the length options - semi weight

[dusky gate]

That's what I kinda figured looking at the configurator, I wonder why the caliber chart or whatever you'd like to call it didn't show it real well

[nova pivot]

Not sure but thats Blasers barrel options, not sure about the other 2 but I cant imagine it would be too different given 200gr minimum that I'm aware of & a magnum. Magnums never seem to perform well in short barrels.

But I typically never go shorter than 20in and I always use heavy barrels with Witt's MRE Brakes.

With majority of my builds yea their a bit heavy to carry around but they shoot comfortably without getting recoiled out of your sight picture down range. Atleast not often that is. But it varies with my stock choice as well.

[tranquil ledge]

the irony of it was I didn't intend it to be 🤣 Its was the first thought I had when I seen it was a wolf rifle hungry & fierce. A bit cliche but it stuck

yes its made in Germany so I thought it was fitting.

Sadly no & its been years since I tried but I always liked the language. Sorry miss read your reply but both my wife has distant lineage & I have some & Danish.

right, I figured it would be fitting given its a smart magnum for vast ranges of Game much like a wolf hunting various prey & its made in Germany so the pronunciation rolled on the tongue & kinda stuck. With that "ulf" just made it feel strong to me. wierd I'm sure 😅

[nova pivot]

Right it kinda threw me off bc I thought Blaser was a Turkish manufacturer till I looked into it. Mauser will never die & still imho the best action ever made I love them.

yea I was planning to order an R8 but I'm running into issues getting RWS to send me the reload data for the 10.3x68 since its not publicly open. I can easily order components & ammo from them but no one seems to have any reload data. Valrag has sim data & thats as close as we've gotten.

Its been in production since 2018 & I can find everything but the data & its still very much in use. I've read articles from Canada, Africa, EU, & Austrailia talkin about it except here in the states. It was orginally designed to be available to use in the Swiss canton of Graubünden , where a minimum caliber of 10.2 mm (.4015in) is required for hunting with firearms. As the all in one magnum for EU & African Game. Valrag found the dies for it Blaser has it available in the rifle builder & RWS sells the componts.

[hexed citrus]

Sounds like an exotic and very expensive round

[nova pivot]

it is based on my findings I have it somewhere in the thread.

[hexed citrus]

10.2 mm is needed for every animal in Graubünden? Poor smaller game animals in graubünden. There ain't not much left of them. Sounds a bit unethical.

[nova pivot]

But expensive rounds is something I'm no stranger to given my Lupua Brass & hazmat fees for powder.

[nova pivot]

not really if you look at the local caliber its alot like the gandhare based on what I read. The 10.3x68 with the 200gr performs like a 30.06 were the 400gr is comparable to the 416 Rigby.

but I doubt the locals would waste bullets on small game I would bet anything they trap for those.

[nova pivot]

Its probably a regional thing. I haven't really seen their ammo on the shelves either so its likely a thing with trading atm.

[tranquil ledge]

But a General answer should still be possible

[nova pivot]

yea your not wrong there. How about you have you tried reaching out to RWS? Figured you'd have better luck being in the same region?!

@tranquil ledge @slate mantle after searching forever I finally found something. 198gr-300gr Loads using various bullets .411 - .413 https://www.xxlreloading.com/calibers/10.3-x-68-mag

[tranquil ledge]

@nova pivot will try my luck

[tranquil ledge]

Too Bad this Page wants a Subscription

[nova pivot]

Yea if you get a response that would be sweet. But at least I found a source with options.

Only took how many months 😂 but we finally have data. Though RWS offers it in 200gr now according to their site & products. I'd wager the 400gr is a special order. On the upside to all this the source I found has various brands to use & not just RWS bullets. I'll take the win either way.

[slate mantle]

Hey, reloading it makes it way more viable for any hunters tbh

[nova pivot]

Wont argue with that. I'm so happy with this find. Now I have to window shop since I have load data.

[slate mantle]

Honestly window shopping is the fun part, then you have all kinds of new things to think of and look at

[nova pivot]

Very true esp. since I have a powder list I can use it to verify who carries it locally. & I can look for bullets as well. Dies however I might have to get a custom order from Hornady or RCBS cause I'm not sure if I can get them imported. Brass is a gamble. If I had my choice I'd reach out to Nosler, but accessibly Hornady is easiest.

I'd work with RWS but I couldn't get a response which hurts bc I do like their products from past use.

Come to think of it the 10.3x60R & 405win both use .413 bullets if I recall. Next size up would be the .416 (10.57mm). This is likely why we dont see it here in the US bc of the 405win & 416 Rigby.

The 10,3x68mag would pair well with: https://discord.com/channels/393040947006406657/1126572984509931592 & would add alot of player utility** "with both ammo options to hunt various game"** -(•200gr Polymer-tip [3-7] --- •400gr Soft Point Round Nose [5-9])- adding more player flexibility. If released in a weapon pack: •10,3x68 Magnum [3-7] / [5-9] •9,3x62 [4-7] / [7-9] •8mm Mauser [3-8] as a Euro Pack would be solid all around.

[nova pivot]

If EW considers adding the 10,3x68 Magnum I'm 🙏 it'll be referenced using the "Sauer 404" with the**"(Wood Thumbhole Stock & Straight Bolt Action)."** I Truly want to see more Thumbhole stocks added to the game. I was a bit disappointed that the new 410ga was not a traditional wood thumbhole stock model.
