RE: choke for heavy-shot?
I have the Super Max choke for Hevi-shot, made by Mad Calls (same company that makes the Mad Max chokes). I shoot this choke on my Rem. 870 with 3.5inch Hevi-shot 6's. Patterns are better than anything I have ever used with Hevi-shot. I've probably tried 10 different choke combos and this is the best I have found for my gun. Last year I dropped a gob that spotted my movement at approx 65 yards. He started running away, I put the aimpoint on the back of his head and he did not even kick when I pulled the trigger. Just dropped. I usually get around 93 to 95% of my pellets in a 12 inch circle at 45 yards. In all honesty, I would not change from this combo even if rifle hunting turkey's was legal in my state.
