Can you help me cut down on some of the testing?Nothing over 55 grains please.Right now I'm expermenting with different manufactures.Federal 55 grain boattail FMJ's,American Eagle 55 grain hollow points,Winchester 40 grain ballistic silver tips,Pmc 55 grain FMJ's.
I haven't tried the silvertips or the PMC's yet.But the American Eagle cartridge is all over the place.Federal seems to be the best grouping at 100 yards so far.

Yesterday we had alot of wind and the Federal performed the best,so far.

My barrel has a twist rate of 1:12.
