It grouped approx 2" 5 shots C-C at 25 yards off a sandbag rest with the 45 ACP load, military dupe (230 gr cast RN; HP-38, 5.7 grains, WLP primer, Star- brass) and approx 1.75", 45 Colt (255 Rem lead rn, AA#7, 14.8 grains, WLP primer, Magtech brass). Only issue is that I am cross dominant (left hand, right eye) and had to adjust the windage all the way to the left to zero. Haven't had to adjust that much with any other revolvers or pistols. Not sure if it me or the gun.
