I hunt mostly Southeastern ma for pheasants and occasionally quail. Many times in the past I had ducks or a formation of geese fly over me well within range, but I always had to let them go since I was using lead shot. This year, I got my fed and state stamps, and plugged my 870 for 3 shots. I am planning on using 3" Blindside steel #2s for my upland hunting and if I get the opportunity to bag a goose or duck, I will. Does anyone else do this? Other than possibly having to let a pheasant fly a little further before shooting, is there any downside that I am missing? Regulations say that you can hunt upland with shot size no larger than #1. I think this is all legal.
