Did you check that stock screws are properly torqued? I have had the heavy barrel version for about 3 years. I will shoot hornady black to about 1.0 MOA, but will do better with handloads. Yesterday morning I shot these groups at 100 yards off a rest, diameter of inner circle is one inch. The group on left os 0.69 MOA, group on right is 0.45 MMOA. Leupold scope at 20x. Bullet is being pushed by 27.2gr 8208xbr
