I used one ounce number 6's, 28/ ga. for ducks for many years. Over decoys it was magic in my model 12. Back when I had good eyes, reflexes and the ability to use lead shot for ducks. The good old days.

I have used the Sporting Clays load for released birds with good results. Fact is that its not the arrow, or the bow but me who misses most birds these days.
