So I did some testing to see how the Moradi .44 Mag compares to the Laperriere, Withlock and Coachmate but Ill specifically focus on the Moradi and Laperriere.
I first wanted to see what the drop at range looked like for the different calibers.
At the Hirsch Shooting range using 200m targets and 150m zeroing on all the rifles with point of aim being on the bullseye, what I found was that the .30-30's had the least drop and the .44 the most.
In practice, I tested on fallow deer at 96m, 150m and 200m and the results were as unsurprising as they were depressing. At all ranges the .44 basically achieved pass through, the .30-30 at least managed to just get double lung, the depressing part though, is that the .44 dropped the deer at all ranges like a sack of rock where as the .30-30 achieved about 98% quick kill at 98m, 90% quick kill at 150m and 74% quick kill at 200m.
Anyway I think its proven beyond reasonable doubt that pistol cartridges are OP asf in game both on paper and in practice.
Ps. I'm pretty sure the Laperriere has a longer barrel than the Withlock, but their external and terminal ballistics are pretty much identical so I think barrel length doesn't affect ballistic performance in game, but rather, as I recall Jaxy saying, the weight of the rifle in game
