I concur with my semi auto bergara carbon I can do 1/2 inch all day,pretty amazing stuff,Eley match close second, and Wolf match a contender I can't ask for more than that.Lapua Center X is really good stuff with right lot for your particular combination.
I've shot dozens of sub 1/4 moa groups at 50 yds, 50 meters, and about the amount of sub 1/2 moa at 100 yds. All in competition.
