Leather Cartridge Belts and Corrosion - True West Magazine
True West Magazine Anson Mills A question came in the other day from a True West Magazine reader. “I’ve noticed that my leaving a cartridge in a leather gunbelt for an extended amount of time will turn the cartridge green where the cartridge and leather touch. I was wondering how the guys in the old west handled this? I am aware that they didn’t use up a bunch of cartridges each day as Hollywood would want you to believe.” Those guys in the Old West had to constantly remove the cartridges and clean them lest they cause the pistol or rifle to jam.
