OK I handload all of my ammo. I have never stored any ammo longer than a couple of months. Is there a wash or coating that you can run loaded ammo through to preserve it so it will deter corrosion (green copper corrosion) for a very long time. I know they wont stay fresh out of the tumbler shiny for long but I want put up several thousand rounds in ammo can and dont want to have to worry about corrosion. Any help is appreciated.
