thinking about lining a smooth-bore with a lathe turned rifle barrel as detailed in the thread:

the bore is around .590 at muzzle but may vary, and i have no means to long-drill it to a guaranteed uniformity. i can turn the insert to fit. how close does an epoxied-in-place liner have to be to hold the barrel in place for a cartridge of the type that i am proposing? what epoxy?
thanks
