After finally coming across an indoor range that allows shotgun, I took my new 590A1 for it's first good work out this weekend. I'd put one box of shells through it before, with no problems.
This time, however, I had a serious malfunction. About 3/4s of the way through a box of Winchester #7s (lead shot--the only kind allowed on the range) the pump froze up solid. I could not budge the pump to eject the spent shell. After a few minutes of struggling with the pump and the action release, I got it open and emptied the gun. Loaded it up again with three shells and had the same malfunction after firing the second one. Same process: a few minutes of working the pump and action release finally freed up the shell, at which point I packed up, took it home, and gave it a cleaning.
Nothing appeared wrong and I couldn't replicate the malfunction by just cycling shells through without firing. Could this be an ammo problem? Is it possible for the spent shell to swell from the heat? I've heard that Mossbergs come packed with grease that you can't get out with a normal dissassembly. Could that be fouling the action somehow?
Any tips are appreciated. Thanks.
