Hi
I am planning on developing a load for my 20", 11/1, 308 with Berger 185 juggernaut, vv n550, cci 250, lapua brass. I want maximum safe velocity and my question is: Do I really have to start at the minimum powder amount in the load manual to be safe?
It is about 41grains and to me it seems...
Anyone getting this type of speed, or is my chrono whacked? Shooting a 26" GAP 46.5gr of Varget. just slight marks from the ejector, but no signs. 15 round recorded, and all a little above 3200fps not much deviation in FPS, next is to try it at diffrent ranges.
