My brother in law inherited an 8mm Mauser that his grandfather brought home from WWII. It's in great condition and he wants to use it for his deer rifle this year and keep it in good shooting condition. He asked me to find some match grade ammo for it, but can only find surplus ammo or 198gr PRVI Partizan FMJ. Does anyone have a suggestion on where to find it or what to use? I know nothing about PRVI. Thanks for your help.
