I've got an older 870 3" gun that I was planning on toting this year. Have two turkey chokes, a Truglo Gobble Stopper Xtreme(I think it's a .665) and a Comp-N-Choke .665. Anyone have a suggestion for choke/shell combo? I figured it'd be hard to go wrong with some #6 Longbeards, but I know that stuff patterns SUPER tight inside of 20, so you better be holding it on them pretty tight.
