I shoot the 3" 15 pellet 00 Winchester Super X with a full choke. Killed a pile of deer with that combo. I feel comfortable shooting to about 60 yards. I have patterned it at 80 and can still consistently get hits on target but that is pushing it a bit, mainly because of velocity at that point. I have shot it though xxxfull comp-n-choke. It did great. Could put all fifteen in a 6"circle at 40, but it ruined the choke. Never fooled around with the 2 3/4 stuff too much.
