Re: Rem. 760 Gamemaster - cartridge ejection problem
I had something similar happen to mine a few years ago. My problem ended up being that from teh sling being attached to the front of the forened, it had slightly bent part spring in under the forend. The spring would allow to much play when I would try to eject a spent cartridged, and I had to work like heck to get the casing out. I end up taking mine to a gunsmith, who fixed the problem and have since to a barrel band on for the slind. Not sure if this is your problem or not, but you may want to look into it.
