I am just curious. Has anyone ever made a TiN plated barrel "the bore"? I have seen chrome, and nitrided barrels, but never TiN. I am curious why. It seems if chrome would work, TiN would be better? What other treatments to the bore have you men seen? Chrome lined barrels have a mostly great reputation when used as intended. With modern industrial coatings and platings being very good with lots of choices for different uses, I was just wondering if any of these might be useful for barrels, like hard chrome lining of the bore. Nickel boron perhaps?
