I got a thumblers tumbler. Its uses water with dawn type soap and lime away for water spots, and stainless steel media. I tumbled some, well a lot of 300 blackout and 223 brass for 3 hours. They came out looking like virgin brass, even the primer pockets were spotless. And the kicker is that inside was also spotless. there was no carbon residue at all. No more dry media stuff for my nosler brass.
