22 silhouette matches have targets at 40 meters, 60 meters, 77 meters, and 100 meters. In my experience with match rifles, shooters would puke with 2 inches at 109 yards, pretty Ok with 1.5 inches, and lottery winners if under an inch. Really with wind, things happen.
Any shooter who is competitive would only have nightmares about using Minimags too. Anyone serious is using Midas or some such.
As a bonus, you'll get less wind drift with the low velocity match grade ammo.
