Although I shoot a Beretta A400, I haven't shot anything but steel 'off the shelf' loads for years, and never anything bigger than three inch loads. #2-#3. #2s for the big Honkers, and #3s for all ducks. Often have the Honkers so close I don't even blink an eye at spraying them with #3 shot at 15-25 yards. 40 yards in a pinch. If the Honkers are showing they are to be the hunt on any given day, the big ducks make do with #2 shot. I've yet to hear one of the little Blighters complain.
