Sorry, I disagree. The ammo is causing the sticking cases, not the chamber in any of my rifles. I can shoot Albanian, Russian, Polish, or commercial ammo all day long and they all extract like butter. I shoot the green steel cased stuff and after about 6 rounds, I need a hammer to open the bolt. I have an extensive collection of Mosin Nagants and they all are that way......chris3
last time. the primary rounds used by ex-eastcom countries are the old ak rounds or the updated smaller ones. Not sniper rifles or crewed? machine guns. if you don't want your mosin to lock up clean the chamber and stick to(get it?)copper washed rounds and buy them now 'cause they are going away. out.
a 20 gauge shotgun brass brush works just about perfectyou gotta ream out the chamber with brushes in drills and steel wool and stuff. or maybe you got sold a crap gun,they do exist,you know.
