I haven't hunted geese or ducks in quite a while. But back in my younger years we used to hunt them a lot. It's illegal to shoot them on the water here, but I've shot wounded birds on the water. The other issue I'd have with that is hitting the decoys. I was doing a lot of waterfowl hunting when they made lead shot illegal. I think we had a lot more wounded birds using steel. I've never used Hevi-shot.
