My best luck has been the 3" Win XX Supremes in 2oz. #5's. I've tried the same in 4's, 5's, and 6's as well as the Federal (normal turkey loads a couple years ago), Kent's, and Rem. Hevishot. None patterned as well as the #5 Winchesters so that's what I use all the time. I do want to try out the new Federals though so thanks for posting. I'm shooting an 870 with the Rem. Super Full Choke. I would like to try another choke but don't really want to drop $50 for something I don't know if it'll help. Might have to check with a local store and see if they'll take it back if it doesn't work out.
