The calibres Jager mentions are found on later models after standarization. Like Steven said, if it is a pre-WWII version, chances are you'll have some variant of 360 Express. But once you slug the bore, get the correct diameter and obtain some cases, it is a joy to reload due to the straight wall case. You can use black, duplex, filler, smokeless(N140, etc.) and see where the best performace might be. You may find that you can use 0.35 Cal bullest like Sierra Pro-Hunter #2800. I have found that using black powder seems to reduce the life of the case. And it is just simply amazing how Buffalo Arms can take 9.3X74R and convert them into 9.3X72R.

All this work for nearly extinct antiquated cartridge generating 180MPa of pressure and about 2400J of energy at the muzzle?
