A friend brought it to me to see if I can figure out what’s wrong. Before starting on it I thought I might get some ideas. Shooting 3 ½ mag shells most of the time, Winchester Supreme. The gun is virtually new, and very tight action. The problem has existed since the first time he fired it.
When the gun is cycled without firing, shell from mag drops immediately into the space below the bolt, on top of the ‘feed lever’ that pushes it up into line with the breech after the bolt moves to the rear. This is as it should be, far as I can tell. Cycling without firing works just fine. Snap an empty chamber and cycle a shell from the mag works just fine.
He says that when you fire a shell, the ‘feed lever’ flips up before the slide cycles, throwing the feeding shell under it to hang up. Not every time, but often enough to make it unreliable. I have tried cycling the action, but haven’t fired it yet.
I’m much less familiar with the 870 (beyond basic field strip) than with the Winchesters I use. Any suggestions where to start?
