280 AI powder choice for 160 AB

Since it hasn't been mentioned yet, IMR7977 is great with this bullet. I get right at 3000 FPS with 61.0 grains. I can push it faster but with cloverleaf groups, why bother. It puts a hurt on deer and coyotes too.
 
Rl26 definitely gets the speed. Accuracy was good enough to hunt with but not compete with. I can't wait to try rl23 myself. Speed and accuracy and temp stable. Everybody says its made for each other. I will try for sure.
Shep
 
I run 4831sc in one and rl-22 in the other. No noticable difference in velocity. 2920 with 4831 and 2930 with rl-22 They just didn't like the same powder unfortunately.
I like 4831sc better, generally speaking.
