After about 1100 rounds of various ammo, mainly Wolf Match, since I have several thousand rounds on hand, the groups have tightened up considerable.
Best 5 groups to date is .538" at 100 yards with Lapua Center X. Wolf Match Target holds a consistent .696" at the same range. Other than finding ammo it likes, the next thing was tinkering the torque. Mine like 13"/lbs on the action screws. As strange as it sounds, 14"/lbs and the groups open up considerably. At 17"/lbs they grow crazy big!
Another thing I've found. Mine like to be cleaned around 140-150 rounds. I notice the groups opening up right at about 140 rounds. After cleaning and 5-8 fouling rounds....the groups shrink right back down, until I hit 140.
