Hey folks, I acquired a type 53 Mosin a while back. Did the usual mosin clean up, taking it all apart and soaking in mineral spirits before brushing and cleaning. The first time I fired it the bolt wouldn't open and had to be beaten open to remove the casing. Scrubbed the chamber again and have the same problem, the case has a ring worn all around the shoulder. Is there anything that can be done beyond more cleaning of the chamber?
