Thanks GB. My 870 is only good out to around 30-35 yards so I'm looking for a way to extend it another 10 yards if I can. Best loads I use right now is the Win XX 3" #5's w/ 2 oz. shot. Better than any other brand I've tried including Hevishot or any other shot size.

Might have to try another choke but who can afford to buy a bunch to try out? They ought to let you "rent" a choke for a week to try different ones in your gun.
