I’m sure I sound like the Village Idiot, but here goes.
At Christmas time I took my grandson to the club to shoot my P32. We shot 100 rounds and he found all but six brass in the light snow and slop. I laid them out to dry and tonight (two months later) I tumbled them a couple hours and when I took them out, two-thirds of them were each partially discolored. The discoloration was an iridescent purple, that rainbow effect you get when you put a torch to copper. The location of the color was not consistent from brass to brass and like I said a third of them were perfectly shiny. It will not rub off with a cloth. A mild abrasive does remove it. I’m not anal about the discoloration. Just wondered exactly what happened since I never had it occur before no matter how crudy the brass was.
Can anyone enlighten me?
