RE: Primers?
I would try using a larger bullet versus the 245. You didn't say what charge you are using 100 or 150 grains. I would switch to the 295 PB's and use a little bore butter on the PB's caps. Cayugad has said this before. I have he CVA Hunterbolt and do have sometimes issues with groupings at 100 yards with the PB's. I can't load the Shockwaves and the Hornadys, I tried them. I can us the Buffalo Ballets but with the PB's I have killed several deer and I'm satisfied with the results.
