I clean black powder brass in a Thumblers Tumbler.
I started out with Dave Maurer ceramic. That and and the green additive that came with the ceramic does a great job of cleaning and polishing really nasty black powder cases. But the ceramic pellets can get hung up in the cases and takes time to separate.

So I got some steel pins from Buffalo Arms. They came with an amber additive. It took a while to get the pins themselves clean. Do not throw brass in with the pins the first cycle, it will come out with an ugly gray film.
After a few uses, I noticed the brass was still getting clean, but not shiny.
So I ran a batch with the green concentrate and got them bright as new.
I will add some Lemishine to the next run with the amber mix.
