I'm a little new to this place but, I have some questions about my 8mm Mauser. I few days ago I took it to the range to fire some surplus Yugo fmj ammo and they didn't work. It's surplus ammo and the primer is sunken in but, the bolt is hitting it; just not enough. Any chance it could be the firing pin not protruding enough? Rather, can anyone tell me or link me to a place where I learn how to disassemble it?
