I have a 6.5x47 Lapua and although very accurate, its popping primers on a all to regular basis.
The load is as follows:- 35.5gr RL15, 123gr Lapua bullets, CCI 450 primers, seated well off the lands - (so no over pressure).
The rifle groups in the .2's and the rounds are heading down range at 2915fps.
I'm not getting hard extractions of any sort, but each time the primer pops a small bit of primer metal gets into the bolt, fowls the bolt and results in an inability for any further shots to be fired till the bolt is stripped and primer metal removed.
Having looked at a number of variables I habe been able to rule out most but am wondering if it could be the firing pin firing to far forward ???
Any help or thoughts would be much appreciated.
