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?

 

[Mtyhunter]

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.

Get that choke out yet?


Telemark, I believe thereis some steel specific chokes out there. Shooting steel or bismuth? Used to use larger shot so it would pass through pheasants and grouse more often than not pass. #4 shot usually.

NY has a law require non-lead ammo on state lands. Do it with deer. Don't mind complying with 22lr, but need to find a solution. Thats when I bump into the game warden most often. I'm the only one around on his boring slow january day.......

Used to shoot a citori 12ga with fixed choke mod/IC for trap, skeet, and hunting. Now I am down to just a 20ga mossberg with a fixed full choke.

Yep , now trying to get rust out of the barrel threads

 

[RGrizzzz]

Also rust in threads inside barrel. Ive been working a brass brush on it but cant seem to remove it

I'd try using some Evaporust on those threads. I'd be careful to only put it inside the barrel and not on the camo.

i used this for the first time a few months ago, didn't even know it existed till then. It worked decently, but, I did let my stuff soak in it overnight in a small tub. 3 rusty car parts and some nuts/bolts I put in cleaned up very nicely. Also had a rusty cresent wrench, and a cheap multitool in there, too. Didn't do so great on these 2. Made me think it had something to do with hardened metal. Maybe they needed to soak longer, idk.
Agree with Grizzz, I don't know if it will for sure, but it could lift the finish. Maybe soak a cotton ball or two, and put them in the barrell

I've also cleaned threads with valve lapping compound. Slather some liberally on the threads, and run that choke in/out about 20 times. Can't imagine any rust would be left in the those fine threads after that.

Keep it wet with wd-40 and run a drill on low speed with a bronze bronze bore brush.

No way it could be worse than a neglected muzzleloader. Done a few over the years.
