I like Winchester #6's out of my 3" 870. They work better than Federals and Kents. They've killed all the turkeys I've shot them with. I only get a decent pattern out to about 30 yards though. I use the Remington Super-full choke. I don't think it's a specialized turkey choke though, just a really full one. But who can afford to buy 10 different chokes and try them? Hard enough to try 10 different loads. Would like to try the Hevi-shot from Remington though.
