I use a 28 ga. O/U with IC and Mod chokes. Fiocchi makes a "Golden Pheasant" load with 7/8 oz. nickel plated, buffered shot. I have found #6s in this load works on everything from quail to sage grouse, and they haven't been real close shots. Like a cousin said " 28 gauge ain't supposed to work on pheasants, but nobody told the pheasants"
