Benchmark, I run more of it than anything. It's temp stable but still meters well. I run it in my 20" RRA predator pursuit with 50 and 53g vmaxes with great accuracy. I even run it under 75 amaxes from my 223 AI.
It's awesome in a 17 rem and in my 22-250 with 40g NBTs it drives them 4200 fps and 1/4" average groups at 100 yards. My old 6mm even loves it under 55g NBT's at 4000fps.
If I had to narrow my rifle powders down to 3 or 4 Benchmark would stay.
