In my youth I killed hundreds of ducks with my 28 gauge Model 12 Skeet gun, using one ounce factory loads in 5's & 6's hunting a creek under 25 yards wide. Those loads were traveling about 1100-1125 fps. I have tried reloading them with powder available at that time and 1125 is about the maximum I could generate. Now with newer powders, I am sure 1200 fps is obtainable these days. But slow is more than capable of working under the right circumstances. Pattern the load and figure out how far it will work properly. You are not going to kill birds well at extended ranges, like 50 yards, using slow loads. Under 35 yards and they will work well i suspect if the shot is large enough to retain good energy.
