Need Help

[wildweeds]

Small metal can,with 3 inches or so of kroil in it,hang the gun with the barrell down in the can,and leave it for a week,For heat I would shoot a box of cheap lead 8 shot shells through it fast,and then get after the choke with the choke wrench,twist until it stops and then screw it back in,basically what your going to do is recut the threads with the old threads,If you manage to get it out make sure to grease the thing on regular occasion from here on out,the next time you may find yourself with a fixed choked barrell forever.My buddy made this very same mistake with a ruger red label over/under the gunsmith who refinished it couldn't get his out and now it's fixed imp cyl and modified.As a welder I can say there is another option with cold,you could head to the welding store and get a thermos of liquid nitrogen and freeze the choke from inside the barrell with a qtip on a stick,there are a lot of things we get unstuck at work that are similar,we use either liqud nitrogen or Ice,you could preform a cube of ice with a tube of same inside diameter as your choke and send it to the muzzle from the breech,the trick is to wait just the right length of time,if you wait to long the outside will constrict as well and put you back at square one.

Thanks for all the advice, I'm not too big on trying the heat to the gun. Don't want to do too much and damage the camo or the barrel itself. It sounds like kroil is gonna be the winner. Maybe even a few more cleans a year also. This was one of the first times I've actually cleaned it 2/3 times, but never took the choke out. And I've had more problems with it jamming thi year.

Don't forget the April 2007 "Machinist's Workshop" magazine comparison test.

They arranged a subjective test of all the popular penetrants with the control being the torque required to remove the nut from a "scientifically rusted" environment.

Penetrating oil ......... Average load
None ..................... 516 pounds
WD-40 .................... 238 pounds
PB Blaster ............... 214 pounds
Liquid Wrench ............ 127 pounds
Kano Kroil ............... 106 pounds
ATF-Acetone mix............ 53 pounds


The ATF-Acetone mix was a "home brew" mix of 50 - 50 automatic transmission fluid and acetone.

Note the "home brew" was better than any commercial product in stores. I doubt if this brew will harm the bluing, but you might want to try it on a spot normally hidden by the stock first.

For heat, a HarborFreight tools heat gun is much safer than a propane torch. You can get them for under $15.

What you want is a temperature differential between the choke tube and the barrel. I would crush up an ice cube and wrap the ice in a small rag that will fit inside the choke tube. Then, heat the outside of the barrel using the heat gun. Before the heat gets to the choke tube, try to remove the tube by turning it both ways alternately. You'll get it.

Interesting, I've never heard or read of such. I'll have to try it in place of Kroil next time it's needed.

Hammer it works very well,actually it's been reported that it's a better brew by many a millwright.If you do a search for "Ed's Red Bore cleaner" a similar recipe will come up for cleaning rifle bores,it's a version of milspec barrell cleaner that was used by the military in WW2.I mixed up a batch and found it to be an equal to hoppes 9 if not better.There are about three different things you can add to the mix for different purposes(copper removal,and long term storage are the two that come to mind right now)

Eastside, I have some Ed's Red I could spare if you want to soak in that.  PM me with your phone if you're interested.
