[QUOTE="Coldfinger, post: 1995748, member: 113278"] Don’t get stuck on speed or the other complications like SD. The .308 isn’t a speed demon to start with. I chase groups till I get what I like. Rarely do I worry about the speed unless I’m planning on heading west and want to look up ballistic data to get me on paper at my self defined max ranges. I love 4064 in my .308 and it’s one of my most neglected powders. Depending on barrel temperatures your groups do odd things. I try to shoot 3 shot groups. I happen to have a great shooting hunting rig that I decided to run a full 10 round magazine through as fast as I could just to see what happens. First pic is 3 @100. Last pic is 10@100 those are 1/2” square grids. Either an ok 5 round group and 5 missed the paper or a great 10 round group imho! Sierra 155 grain mk IMR 4064 Winchester brass and CCI BR2 match to light it! [/QUOTE]
