I really like the Winchesters in #4 through my 12 ga. It has wacked them good out to 50+ yards or so. I've seen birds roll and then fly with the 5's, so I stay away from them even though some of the best turkey hunters I know use them effectively out to distances that amaze me. For the longer shots if your hunting more open areas I would recommend a heavier size shot or a 3-1/2" gun.
