I shoot an 870 with a Jelly-head choke, but use Remington Wingmaster HD #6 shot 3.5"...devastating patterns. The Wingmaster HD's are 10% heavier than lead, and a bit cheaper than the Hevi-Shot. I bought 5 boxes on sale for 16.99 each a couple fall's ago and it has been one of the best purchases I have made. I have shot the Hevi-Shot #5's through this gun, and the patterns are very similar, but I'd have to give an extremely tight nod to the Wingmaster's. Give them a try...bet you'll like what you find with them.
