88's, lapua brass, Harrison spout, 2.27", MPI 7.62x39 bolt,
Tried tac, 4166, and 4451 and they all popped primers under 2800 fps. There wasn't much gas and no pitting on the bolt face or firing pin. I swapped in another pin from my 6.5 grendel that has never given problems and it popped them as well.
Some of the primers that aren't pierced show signs of cratering.
Primers are either CCi 400's or 450's, I forget which as I primed them awhile back and set it all aside but I have not had a problem with either in other rifles. Any help is appreciated, feel like I'm missing something here.
