I tumbled 140 30-06 cases with a bit of citric acid (not a lot at all), some Dawn dish liquid and the saved liquid I previously used that had whatever Frankford Arsenal gave as a free sample when I bought the tumbler. They came out after two hours looking pretty good. I rinsed them briefly and dumped them onto a towel to remove most of the water. Then I put them into the toaster oven for one hour at 275*. They came out with a dark, iridescent blue/purple color to them. Other than looking odd when loaded with a bright brass bullet, they look kinda cool. However, I'd like some reassurance that I didn't harm them in any way that makes them unsafe. What thinks you?
My pictures were too big to upload, but I'll get to work on that and try to get them posted here for reference.
