Use Krol Oil
Confucius says trying to save money by not going to gunsmith costs more money when you go to gunsmith.
Oh I'm sure we could, it's just like FB, folks read the question, and then answer.............without reading the previous posts, suggestions, etc lol.
First, have you spoken to Briley Choke Manufacturers in Houston, TX yet. Seek their input. They are the gurus of all thingys shotgunny. Kroil often works where others fail. Introduce at muzzle end as well as inside barrel at junction of barrel/choke cylinder. Making a dam in barrel just below choke/barrel junction allow soaking by flooding barrel above the junction level. Soak for several hours/days. Let soak, then add heat to external of barrel directly over thread area, for thermal expansion allowing Kroil to penetrate minute crevices formed through thermal expansion. Combine mechanical shock with thermal shock. Rap the thread area with a plastic hammer during thermal shock. This can take more arms than one is usually issued. Have a friend assist with rapping, covering barrel with protective covering to prevent finish damage, etc. For maximum thermal shock to promote breaking the thread bond, try placing barrel in freezer for an hour, apply torque with heat gun to external surface over thread area. In couple extreme situations, I've had to thermal shock several times. Also, might try tightening the choke prior to loosening during a thermal shock to break the bond. Using the dam/blockage just below junction line, apply dry ice inside barrel for maximum thermal shock. Dry ice also tends to introduce thermal harmonics as it rapidly, excessively cools metal. Also, shooting the shotgun alternately between attempts assists bond break with internal expansion stress. All else fails, send to Briley in Houston.
That's MY line.....
I just wanted to wish you luck and help this get another page.
Please. Everybody knows you should be asking if it’s still for sell.
