I just got a chance to try superformance the first time yesterday in my custom 6mm Rem with a 25" 1 in 9 Kreiger barrel. I worked up to a max load of 54gr from their website and the 6 rounds I fired averaged 3824fps. All stayed within 33fps variation except one that I let sit in a hot chamber while waiting for wind to die down. All 6 shots went under 3/4", with 5 within 1/2". I used the 70gr ballistic tip. It's not the best bullet for dialing in at extreme ranges, but it should allow center holds on coyotes to 350yds without adjustment. Heavier 75gr bullets topped out at 3550fps with 50gr of powder in my testing. I have not yet tried anything heavier, if they get more load data out I'd like to try this powder with a 90gr accubond. A 90gr accubond pushed around 3300fps would be a great all purpose load to build a turret for.
Has anyone else tried this powder yet?
