Works Really good, but two weeks ago i had a heavi-metal shell malfunction. It just sort of hissed and shot out a cloud of smoke. It was scary I thought my gun was going to blow up. I had a similiar issue malfunction with a kent shell.
Anyway from what I've experianced they are very good shells in terms of killing ducks, but just like kent they are not all waterproof if you get them a little wet.
