Well 1st off my wife's is a factory Remington, thought I should clarify that point. Started with some 143 eldx and rl22, had it shooting mid .2's @100 holding a Inch@ 300. Oped up to an inch @100. Next 130 Berger ar hybrids, again mid .2's @100 holding 1.25 @ 300. Last time I shot this load I'd have been better off using a 12 gauge. Now were trying 123 amax .5 at 100. Shot 3, 3 shot groups @300. Agian holding just over an inch. But will it stay consistent? Time will tell, either way it is just a factory rifle that my wife hunts with, and I'm tired of screwing with.
