My problem started with a delay in the rifle firing. A friend suggested squirting some cleaner in the bolt and this seemed to cure the problem for a bit. Then I fired the rifle and not only was there a delay but the bolt stuck!! I bought the proper tools and completely dissassembled the bolt and discovered some surface rust on the firing pin. I cleaned it up with some 220grit and reassembled the bolt. After firing the rifle four or five times it did it again!! Now I know I need a new firing pin/spring and that sanding it was just a temporary fix ( I thought), but can the problem i'm having with the firing pin cause my stuck bolt? Thanks. I'm shooting factory ammo and don't believe my bolt problems are pressure related. Once the bolt breaks loose it is quite easy to move. It also doesn't do this everytime. Thanks.
