410 shotguns are difficult to shoot. They should be used by expert shooters. I was a shooting instructor for Remington and our professional target team used nothing but full choke in the 410. You do not have enough shot to give a even pattern in a more open choke so all you get is random hits. IC and Mod are too open. Most any thing can go through the pattern. It is too long a shot string with too little shot. A 410 is not near as effective as a 28 gauge which has a shorter shot string.
