I've got an Interarms Mini-Mauser in commie-caliber and am not having much luck with accuracy. The barrel has a .311" bore and doesn't cotton to .308" projectiles. My best groups come from using Russian made hollow-points with a moly coating. Obviously, they are .311" dia. I have heard that hot loaded .308 "varminter" bullets will slug up to the bore because of their softer lead and thinner jacket, but I have not had the opportunity to try them. Anybody had any experience loading for this gun?
