Stevens 350 locking up

[Willies]

Having intermittent issues with it locking the spent shell in the chamber. It doesn't want to cycle. Seems to only do it when there's a shell in the tube. Has anyone had this issue or any ideas of why this might be happening?

Cheap shells and a rough chamber?

i have one never had any issues like that. i shot fed's, and some old #### that my hunting partner had and worked fine.
i have a friend that complained that his wouldn't eject right till i told him to stop short stroking the pump and since then all good
