Maybe the #4s break open more than the #2s I am using (unless you are seeing splintered #2s too). Although, I think @A5 Sweet 16 uses #4s in full choke and doesn't see a lot of splintering either. I believe that is 1 oz in his 16 gauge. Maybe ducks just have thicker bones that cause more splintering. I don't know.
Yes, I shoot Boss #4 through a full choke. I see what I'd call very little pellet fracturing. Far less than I saw with Kent bismuth or Bismuth Cartridge Co. (many years ago). The copper plating seems to help a lot. For what it's worth, I believe any fractured pellets you find in a bird fracture within the bird; not in the barrel. If a pellet fractures in the barrel, there's no way any of those fragments will fly into the bird.
