I bough an old Morse 12gauge shotgun but the barrel has been cut down to 12inches, I can get a nitro shotgun barrel for a decent price.
Will the nitro barrel work if I install a breechplug and tap it to screw into the stock? Meaning that the pressure of black powder is supposed to be lower than nitro powders or am I totally wrong?
Obviously the chamber for the cartridge will be removed by cutting it off on a lathe.
