I finally was able to shoot beyond 100 yards. I set up some paper at 300 yards and fired a 3 shot group with the best performing 100 yard load. This is a 7mm Rem. Mag. The group measured 1.824" Is this decent? Is this a sub-MOA group? From what I understand anything under 3" at 300 yards is sub-MOA or am I mistaken? Thanks for any help.
