I have an 1100 in 3" that will only shoot "premium 3" shells.It will NOT cycle regular 3" shells.I have changed the rubber "O" ring, cleaned it, and everything else I can think of.I just shoot premium shells through it.

BTW I forgot it mainly does not cycle right when it is really cold.Once the gun is shot a few times or the teperature rises it works just fine .Go figure.
