I have been reading some data on the primer change but wanted to give my personal results to see if others see the same thing. I use 59.1 Grains of H4831SC which yield me 2890fps with a 6fps spread and .4 moa 5 shot group at 100. Decided to try a 210m primer with the same load which netted 2823fps with a 5fps spread. My rifle lost 67fps with the exact same load and a 210m primer but the group stayed pretty much the same.
I can not get any speed from the 180 berger no matter what powder or set up I try. My rile shows pressure even at the bottom of the loads I use but the 175 ELDX seems to shoot awesome. The Bergers will shoot but at 108fps less with the same load. I am sure there is a reason but I would like to have a conversation wtihout all the "you need this powder BS" I hear. RL 26 gave me no velocity but RL 17 with the 162 gave me 3086fps with a awesome group.
