Earlier this week I wet tumbled some 45 Colt brass. After drying, while putting them away I noticed one piece of brass had a good primer in it. Yeah, I had accidentally mixed some brass that I thought I had correctly separated. Anyhow, just for kicks and giggles, I stuck the brass in a gun and darned if it didn't still go bang! That was after 2 hours wet tumbling with Armour All, a drop of Dawn and Lemishine.
