I have a 22 250 fluted,a 204,and a 24" 223. None of them will shoot less than 1 1/2" with factory ammo,but the 22 250 has shot 1/2" groups with handloads 1 time. It shot 3 groups at 1/2" and then went crazy. The 223 went through 400 rds.of assorted bullets,7 different powders,and every primer known to man before it got down to .6". I'm still working on the 204.I thought it was me not shooting my best,but the loads I'm trying in my 12bf 204 are still shooting 1/2" and less. Digger
