trouble with 11-87 super mag.
Dear fellow shotgunners, I have an 11-87 super magnum that is giving me problems and I was hoping for some input. It shoots fine sometimes, but then all of a sudden it will jam open, halfway through its cycle, with a live shell on its way into the chamber. It will not remain open, but will finish the cycle after a 1/2 second delay. Sometimes it fires without jamming, but cycles slowly. Any answers or ideas would be appreciated. Thanks, Mike.
