I use 2 3/4" winchestor foster style in my 870 with choke tube. Took one last year at 110 yds. Dropped right in her tracks. Confirmed the range with a range-finder just for my curiosity. I also use lightfields, and copper solids in my other gun but that one is fully rifled. Lightfields shoot well out of the choke tube but I would recommend a fully rifled barrel for the copper solids.
