Benchmark, H322 and Reloder 10x (I am in the AR-Comp (#1) and 8208 (#2) camp, but not for this bullet)
20 Wilson Arms 6.5 Grendel (AR15):
Benchmark (pressure test)- 29.7-2715; 30.5-2775; 31.0 - 2850; 31.2: 2857, 2872, 2889 (pressure, back off)
H322 (pressure test) - 29.5 - 2804; 30.0 - 2858; 30.3 - 2870 (pressure, half-circle; 30.6 - 2900 pressure, full circle); H322 @ 29.8 - 2825; 2801; 2822; 2816 (sub moa)
Have not had a chance to test R10x, but reports are that it's as good or better than above. I'm not sold on the Absolute design over Hammer Hunter or HHT for speed. You can probably push them a little faster, but it seems the claimed benefits (300-400 fps over) are uncommon. Maybe an additional 100 fps at best, depending on weight and cartridge being loaded. This is what I found with .280AI as well. Ok bullet capable of ok accuracy in my rig, but think I'll try 99 Hammer Hunters to see if I can get back closer to 1/2" groups at 2750- 2,800 fps.
NOTE! Loads above exceed max. charge weights and I am not recommending these recipes. Proceed with extreme caution.
