Marlin Model 120 spent shell sticking

    Hi this is my first post, hopefully this is in the right spot. I have a Marlin Model 120 in excellent condition but sometimes fired shells stick in the chamber and almost cannot be removed no matter how much force you use to retract the pump. Gun has been cleaned, looks brand new, and even sold it to a guy who thought he could fix it but he brought it back after not being able to solve the issue, either. Any ideas? Thanks

    Are you by any chance shooting Winchester Value Pack shells from Walmart?

    If so, that right there is your only problem.

    Try almost any other brand of ammo.

    Unfortunately it happened with different brands, seems random. Sometimes it cycles, sometimes it sticks.

    Well, next step is to polish the chamber.

    You can do it yourself with a split dowel rod, a drill, and a flap of 600 black Emory paper.
    Just keep the drill moving back and forth and let the emery paper do it job.
