A gunsmith removing the case is cheaper than a new barrel.
I have used this method but you must be carful , use as a last ditch.
1 Degrease the with rubing alc.
2 Insert a plug in the sholder area of the case ,NOT past the neck in the barrel
3 turn the gun muzzel down and clamp to hold
4 mix up some 5 min. epoxy and fill 1/2 of the case ,I use a syringe and vinyl tubing
DO NOT get epoxy anywhere but in the case ,you can realy mess up the gun.
5 wait over night and tap case with range rod
If you have even the slightest dought ,don't use this method go to a gunsmith!!!
