What powder would you recomend for 1000 fps out of a 4 5/8 blackhawk? I've always used 18.5 of 2400 with bull-x 255 grain swc at 1100 fps, but when I tried this with the beartooth 255 wfn I got 950 fps with a 150 fps extreme spread. Maybe because the bullet is shorter I need more powder to get consistent velocity? Maybe a magnum primer? Does anyone get good accuracy with this bullet? Thanks
