For a muzzleloader, I'll hunt with and gun/load combo that will print 2" groups, center to center, at 100 yards. I'd doubt I'd take a shot much past 150 yards, so that's more than enough to do the job. For a CF rifle, I just won't keep a rifle that won't print 1" or better at 100 with handloads or 1.5" with factory ammo consistantly.
