Well, Im off to another muscovy duck job. I need an ammo that is heavy and piercing, as these particular ducks are very thick and dont give an easy sight picture.

Everyone suggesting slugs when the man has an armada. Basically an Mrod barrel. They don't usually do well with slugs. Hybrids may be an option, but the 25s are on the slow side in stock form.
I vote baracuda if the gun will shoot them, my jumbo loves them and slings them over 850 fps. Other option is polymag or metal mag.
