You've just got to try a bunch of different kinds to see which patterns the best. In my 20 gauge I use an extra full Hunters Specialties Undertaker choke with Federal premium mag-shok #5 turkey load with a "Flitecontrol" wad, and of course its a 3". Last year I took a 24LB turkey with a an 11" beard with inch and a half spurs. Only $10 a box to. One of my friends paid $50 for a box of 3.5" 12 gauge turkey loads only to do the same thing I can do.
