I ran a bunch of cases through my Dillon FL2000 tumbler this weekend. While I had the bowl empty, I noticed that a "skin" of some sort had formed inside the bowl. It didn't readily scrape off with a fingernail and felt sort of plastic like. I don't know if this is some sort of deterioration of the bowl material or a build up from media. I have only used corn cob with Dillon's polishing liquid in it.
Has anyone else seen this? Anything to worry about (like I need to look for another worry)?
Thanks,
John
It might be some build up from the polishing liquid. So long as your cases are coming out well polished, I wouldn't worry about it. If it really bothers you, try cleaning it off with something like Simple Green.
Is it all black colored? If it is, then I would agree with Billy Ray. Just scrape if out if it bothers you or if it starts to inhibit the action of the brass when the tumblers in use.
I wipe my tumbler/vibrator clean on the inside with plain old Windex and a paper towel. The crud comes out black and green. The media lasts a lot longer, and the brass comes clean faster than when I don't wipe it out.
