Yea went from 31.1 in bra to 29.6 with peterson and H4895My 6BR was shooting sub 1/4 inch groups with Lapua brass 103 V T 30.1 gr. Varget CCI BR-4
CAUTION
Peterson weighs @ 10 grains more than Lapua brass. If copying a Lapua load I would reduce the charge by at least 1 full grain to begin load development.
