Stuck choke tube

[Mtyhunter]

man, I guess I've been lucky, never had a choke tube stick once, and I've put my shotgun thru hell a few times

For those following this thread, in the future you might try diesel fuel. It may require soaking for a month or more. I've freed up seemingly impenetrable stuck chokes and blackpowder breech plugs using this method and a month (or more).

Glad you got it out OK. I second using a little anti-seize.

I have had good luck using choke tube grease on threads when changing. It helps prevent them from working loose when shooting, but also helps prevent them from locking in place.

I also have switched to exposed/extended choke tubes rather than the ones that sit flush in the barrel.

Is there maybe damage here that could let gas through?

Good observation i'm no expert, but it makes sense to be a root cause of the failure

Incredibly detailed observation Telemark! There is a little ding on the end that I'd attribute to over-tightening. Doesn't seem like enough to allow gas escape, but I dunno...maybe? I think I'm retiring this tube and just ordered a Carlsons extended tube as a replacement. Still working on rust removal inside the barrel.

Appreciate all the replies and ideas.

Good luck with it. Choke tubes always make me nervous. The amount of pressure they are subjected to is incredible, and I am truly surprised there aren't more failures.

I recently started shooting lead-free shot exclusively, so I'm especially cautious about my choke tubes.

Thread grease for breech plugs might help.Blaster really surprised me on the projects I have used it. It is better than anything I have used.
