I can't see the Tsurugi as a hunting rifle. It's too long, too heavy and the caliber is just not meant for hunting. It's a "competition " gun for long range matches and that's all. Trouble is, long range hunting goes bad a lot. Animals have much more time to move so the so called perfect shot ends up a gut shot that makes the animal suffer for HOURS if you can find it at all. Cotw has a render range of 400m so anything past that is pointless, but dozens of cartridges can do everything the .338 Lapua can do at that distance, in cheaper, lighter, lower recoil weapons.
The 9.3x62mm is roughly equal to a .338 win mag to me, at least in context of the game, I'm pushing for it because the tsurugi is not my idea of a hunting rifle. If it covers class 4-9 with better penetration than the 7mm that's more than enough for me. I just want an option for bigger animals that's more in line with my idea of a hunting rifle.
A 9.3x62mm in a nice wood stock with good iron sights would be my go to general purpose rifle
