choke tube troubles

eastwood44mag
I know this has been on here before, but I don't remember the results.

Anyways, my choke tube is stuck in my shotgun, and we don't know how to get it out. It's bent my wrench and tore it apart, and the tube is getting roughed up, too. We tried shooting it until the barrels were smoking to make the metal expand, but to no avail. So what do I do now? I can't afford to replace the gun, and I don't have the money to get the barrels shortened and rethreaded. Help would be much appreciated. Thanks.

    I'm not an expert by any means, but I'd try a good penetrating oil, and warming in an oven. I recommend PB Blaster. I've had really great results on all kinds of seized parts with it.

    Most likely the lube you used on the threads has carbonized. Try PB Blaster, Kroil etc to soak the threads. If it still won't come out, you have 2 choices, leave it like it is (a fixed choke), or take it to a real gunsmith and have the stuck tube machined out (no need to cut the barrel) and the threads chased.

    Some guys like a mag full of lead, I still prefer one round to the head.

    Looks like we're going to have fun at my house tonight. It's a cylinder choke in there, which makes it kind of bad to have it fixed. Thanks for the input guys.

    One more thought. I would put a cork in the end of the barrel and let a good penetrating oil like Skunk Oil, sit on those threads for 12 hours. Then use a hair dryer to warm up the end of the barrel (warm from the outside) and give the tube one last try.

    Of course once you get it out, it goes without saying to use a good anti-seize grease on those threads, when you put the new one on.

    Your mileage may vary.

    here is a method i've use several times. clean the barrel and a large hex head bolt (small enough to fit inside the choke tube, 5/8" for a 12ga.). clean the threaded part if the bolt and the inside of the choke tube with laquer thinner or something similar. stand the barrel upright and place a plug in it just above the choke tube/barrel joint. mix up a small batch of brownells acraglass and fill the choke tube about 1/2 way to the muzzel, coat the bolt with acraglass and put it into the choke tube. you are epoxying the bolt inside of the tube. after the epoxy sets up you have the bolt head to wrench on. warm the end of the barrel and have at it. to remove the epoxy and bolt from the tube afterwards just heat the tube with a propane torch to 500/600 degrees.

    eastwood: Heating causes expansion. The wall thickness of the choke tube is thicker than the wall of the barrel, it will expand and actually get tighter. What you want to do is make the choke tube contract, put the barrel in the freezer for an hour, yes both the barrel and the tube will contract. When you pull the barrel out, wrap your hand around the muzzle for about 2 min. the heat fron your hand should be enough to cause the barrel to expand, just enough for you to attempt to remove the choke tube. (Since the choke tube is thicker it will take longer to expand. They do expand and contract at different rates). This is an old manufacturing assembly/disassembly trick I learned a long time ago) Hope this helps you. Regards Dave

    I think one of the following is true:
    Threads are buggered up on either the choke or barrel. Maybe by cross threading at one time. The threads need to be rechased and maybe buy a new choke.
    You could be pumping lead into the threaded joint.
    You could have expanded the choke by shooting steel shot.
    If you get it apart, clean the threads on barrel and choke with gasoline. Use automotive antiseize paste and don't tighten more than snug. Of course before reinstalling the choke, have someone good with small files and stones straighten out the buggered up slots in the choke.
