I have had an SBE for three years and love it. This year I have had a few cyclying problems. I use a variety of shells and I am not sure which shells it has happened with. It has not happened with 2 3/4, but has happened with 3-inch (and 3 1/2 I think - I can't remember for sure) The last instance was with Remington 3-inch steel and it happened once with Remington 3-inch hevi shot.
What seems to be happening is the first and second rounds cycle fine, but the third round comes part way out of the chamber while it is cycled into the action and jams the gun with the final round unfired.
I do clean it regularly, but it recieves heavy use. Any suggestions?
