A friend gave me a box of Winchester AA Steel Trap loads #7's. These are the greatest thing I have found for cripples on the water. They are cheap, low recoil and with the tight dense patterns of #7 shot pellets in the head are almost assured. They seem to be effective out way further than I expected as well. I have started carrying them in one of my pockets and if a bird is looking too lively a quick shot before I send the dog and I have not lost a bird yet this season. No more blasting away with expensive heavy loads at tough swimmers.
