Rifle is a Ruger precision rifle in .223. The load I have been using is a Hornady 75 grain BTHP, LC brass and CCI 400 primers with 23 grains of H4895 with OAL of 2.260. Excellent accuracy at the 200 yds I shoot. I have shot about 300 of these and two times before today I had a situation where the bolt would lift but would not slide back to eject until I banged it with the side of my hand. Today I had another do the same thing and when I checked the case I saw it had very slightly pierced the primer. All others shot fine and never pierced a primer before. Any idea of why this would happen?
