I've had a mossberg 500 for several years, and some how the trigger housing broke so i sent it to my local gunsmith because i couldnt find a replacement. He fixed it and it worked great for about a month, until the first morning of dove season and somehow it got jammed up, so I quickly dissassembled it an got it working and shot some doves, then when i got home i took it completely apart and a small crushed spring fell out of the action!!! I never could figure out what it went in and it has failed to eject ever since. I dont think its the ejector, it could be the exrtactor but imnot real sure. It pulls the shell halfway out before it loses it, and some times it wont pull it out at all, and i have to pry the empty shell out with my knife. any help would be greatly appreciated.
