I'll probably end up loading for it. Strangely, both remington factory loads and Norma Oryx ammo result in a ridge forming at the tip of the neck of the fired brass and a stiff bolt just at the end of the lift. My gunsmith doesn't think pressure is the issue and is looking at it to see what's up. It shoots the Prvi Partizan 8mm mauser ammo to the iron sights at 100 yards and places them as well as I can hold. In either case, I know someone here who makes custom bullets.

This one was made in 1914, what typically were they loaded too back then?
