I was at my Dad's shop, (where we build bullets, lathes, reloading etc...) and he picked up some new tumbling media. I used it like I always use the corn cob media. Well it is the corn cob media with the red rogue in it, and all the brass was basically just stained a tint of maroon after words....:mad2: I'm not too big on having my brass bright and mirror like but I do like them to be basically clean. I ran them through a towel a few times seeing if that would clean them up. The red came off the outside pretty well. But the inside of the brass was still red.. Think it would cause any issues.....I wouldn't think so. But it was kind of annoying you usually use the tumbler to clean up the brass and this stuff almost made it worse. It was the lyman Red Media Just curious if anybody else has experienced this??
