I have a M77 MkII in .223. It doesn't hit hard primers, like military rounds, hard enough to fire. I found out with blanks that if I put pressure on the rear of the striker with my thumb, it will. I have chosen not to worry about it since it ALWAYS will fire with WSR's, Rem., (and regular CCI's usually), so I just stuck with Winchesters. Well now, all I could get was CCI 450's, and of course, no fire. I did put a Timney trigger on it a long time ago, which is great, but I think that somehow this problem showed up after that. No change was made to the spring, and the assembly is clean and lubed. Any ideas?
