Seems as if my 870 express is developing an extraction problem from the tube mag to the chamber. This just started happening after about 1000 rounds. I take it I need a new part, but which one ?
If it is a tube feed issue, check your shell latches. Makes sure they're moving freely and not bent. Also that your follower isn't grimmy and sticking and there is proper spring tension. Lastly, make sure the ramps on the action bars aren't blurred up.
