Hi All! My wife uses an 870 in 20ga with a Hastings choke. Her gun does exceptionally well with Rem Premier 2 3/4" Pheasant loads, in #6. They are copper plated lead, somewhat smaller than a traditional #6 shot, more on order of 6 1/2 shot. About 250 pellets/oz. Fast loads are not supposed to shoot well, but don't tell the gobblers she has shot! Puts up really great numbers at 30 yds. As someone said, lot more fun up close.
