History: WBY Accumark 7mm WBY Mag, Titanium Nitride coated, Sub MOA . Never could get it to shoot Subone inch groups of three. Sent back to Wheatherby and confirmed Sub MOA. Still can't get it to reproduce sub MOA. Tried two different scopes, both brand new, and different ammo. Shot today, first two shots practically in the same hole, third shot 1.75 to 2 inches high. Allowed to cool, hopeing a fourth shot would be back in the group of 2. No, same height, and an inch left. Adjusted scope to lower 2 inches, allowed to cool again (15 min) Again, two shots in same hole, one an inch left. It has shot two shots in the same hole (almost), but never a third producing a Sub MOA group. Regardless of barrel temp or shot order(sometimes 1 and 3rd shot good, or 2 and 3rd). I can cosistently and repeatedly shoot great groups with my 30 378 and 338 378 WBYs, so I highly doubt shooter error. Any opinions welcome?
