Accurate ammo - Sierra Bullets MatchKing 6.5mm Creedmoor 140 Grain Hollow Point Boat Tail Brass Cased Rifle Ammunition

The Sierra 140s seem to be as accurate or more accurate than Hornady Match 140s in my MasterPiece Arms rig. We’re taking 3/4” ish 5 shot groups at 100 probably would be closer to 1/2” if I was a better operator.
