I'm shooting the 22" Unitah Precision Bolt Action Upper in an AR-15 Lower. My results have giving me .5 MOA with low SDs and I'm very happy with the velocities i'm getting (105-108gr at 2750FPS). I'm now trying the Sierra 95gr TMK. However, i'm trying to figure out the COALs for them. I am using the Lapua brass (converted from Grendel).Kool rifle - - I absolutely love the Unitah Precision bolt action uppers. I have a 6.5 Grendel one with some extra barrel extensions to make a 6mmAR barrel for it and maybe a 6mm ARC too. The Grendel upper shoots great - - very accurate. I have one with a .223 bolt face and it's in 300 Blackout - with subsonic loads shooting the 220 Sierras it is scary accurate - - you shoot 3 shots and look through the scope and cannot decide whether you're only seeing one bullet hole or three.
