For the first couple of years I used #4 remington hevishot loads in a 870 with a rem hevishot choke, worked great. now that hevi-shot is their own company, and way expensive I switched to win supreme #5's using a hastings .660 extended choke, at 30 yds 210 0ut of 297 pellets in a 10'' circle at 30 yds. Think i'll stick with the winchester.
