Abstract
A method for lining a gun barrel with a material selected to reduce the rate of erosion and corrosion from the rounds of ammunition fired through it includes the steps of forming a rod of the lining material, hammer -forging a barrel blank to the rod, and then drilling out a bore in the rod. The liner extends from the muzzle end of the barrel almost to the chamber end but stops short to abut a step formed in the barrel just forward of the chamber. The chamber is machined, reamed, and chrome-plated. Preferably measures are taken, such as by applying pressure to the rod during forging, to assure that the rod is placed in full engagement with the step and held in full engagement with the step in order to avoid the formation of a gap between the liner and the step.
