Has anybody else had any problems with a sudden string of light primer strike misfires with their rimfire. Had shot many boxes through this rifle without one problem and all of the sudden several in one session. I took it home and cleaned everything thinking it was just dirty. The next session out same problem, maybe one a magazine. If you lift the bolt to recock it will fire on the second attempt and examining the ammo the strikes look very light on the misfires. No modifications have been made to the rifle, so what wears out on these things?
