I'm currently letting the barrel rest after applying some kroil. I'll let this soak a few days and give it another go.
If this doesn't work, what do you folks think of removing the bullet from a cartridge, tying the rifle to a tire and remote firing it (just the primer and charge, no bullet) to push the obstruction free?
I've done some reading and found claims that barrel bulging or failure from firing a round with an obstructed barrel is caused by the bullet coming to an abrupt halt in the barrel and immediately transferring all it's energy to heat in one small area, causing the barrel to deform or fail.
With the bullet removed from the cartridge, the expanding gasses from the charge are all that's going down the barrel, and this is typically not sufficient to deform the barrel or cause it to fail.
Considering the material that's lodged in this rifle, I'm rather confident that this would dislodge the obstruction, or at the very least, disturb it enough to make hammering it through possible.
Opinions?
