Original Brass Shells

[David Noble]

If you have multiples, I see no reason to not load a few and shoot them, albeit with fresh components. If you're shooting the gun, why sweat loading and shooting the brass cases?

It won't hurt the value if you CLEAN them. Heavy crud can be carefully scraped off. A brass bristled 'tooth brush', from your local hardware emporium, can be used vigourously to remove various forms of verdigris. Quite often the brass will remain stained, which is understandable. Good Luck!
