I went duck hunting this season and only took 1 duck. (First season) Got him on my first shot ever, too. I have been hunting ducks several more times though and haven't gotten another. They fly in and I shoot at them with my 20 gauge with 2 3/4 inch 4 shot and always miss them. Is 4 shot too big for wood duck? I just can't hit them. How big of lead should I take on them. They fly 20 yards away pretty fast. Thanks
