Any good gas gun 6ARC loads?

Based on well established 6.5 Grendel load data, LeverEvolution generates greatest velocity for heavy bullets, with CFE223 being next fastest.

ARComp and H4895 are identical in performance even though they’re not same powder. I use either depending on availability. These two powders are #3 for speed, but also less temperature sensitive with lower ES/SD. Definitely want to include this powder in your load testing for 6ARC.

22" Craddock RTR barrel

85 SMK
CCI 450
starline brass

30.4gr CFE223 = 2853 ES 27 SD 16.6

27.1gr AR Comp = 2839 ES 12 SD 4.7

Both 0.4's 5 shot groups @ 100yd at temp tested.

I tested 35F - 80F with these sams loads and saw a 4FPS Swing with AR Comp in that temp range where I saw a 76fps swing with CFE223 in that same temp range...

Also a lot less powder for damn near identical velocity and accuracy with AR Comp. 14fps difference.

Accuracy and consistency over velocity all day long for me. And the guys really hammering velocity in 6 ARC those loads are way over pressure in an AR per QL..
