To add to Art's comment:
Regarding target shooting, the X-10 ring on the 1000 yard servce rifle target is 20 inches in diameter.
A 2 MOA Military Rifle is capable of cleaning that target.
Problem is, there are few cleaned 1000 yard targets.................but its not the gun that's the limiting factor.
