Also, I have stopped using media treatment entirely. I'm such a rule follower, I do exactly what the instructions tell me to, but once I dumped in some new media (I used crushed walnut shells from petsmart) and I didn't have any when I thought I did. So I ran it dry. NO DIFFERENCE. It was just a pain, you put too much in and the cases are greasy, the media clumps up, I don't know what benefit you get from it.
Meanwhile, back at the ranch, for separating media from brass, I use one of these. 20 turns in one direction, 20 turns in the other direction, less than a minute, done.
