Shot an honest 1/2" group with the factory wby 80gr ttsx saturday with a standard vanguard 24". The gun has had the trigger and crown done but is otherwise out of the box (not sub moa model). Barrel seems to have a copper fouling problem, but that is more of a cleaning issue. Started with a clean bore, fowling shot, then 3 shot group. Only about 75 degrees and gave the barrel a little time between shots.
