I don't know about you guys, but i don't run a tumbler that often..
I run a 5 gallon bucket at a time when i do finally do it.
I got together with a couple of friends and we bought that big Hornady ultra sonic cleaner. We all chipped in and got a couple of buckets for the solutions (one for the gun parts and another for the brass) we each have our own solution in a milk crate and when someone wants to use it, they come over and use it, or take it home with them. Luckily i am the only reloader, and most of the time they bring over their guns and use the cleaner while we play poker on a friday or sat night. Drain the solution into the bucket, and if you want to use the solution in the bucket, have at it, otherwise use your solution to mix a new batch.
Works out really well, and it makes cleaning up the AR lowers, bcg's, and recievers and other bolts really easy.
I can now run the brass in the dry tumbler to kind of clean.. Then size and de-prime, drop in the tank and they get clean inside and out easy. Take them out and put them on a towel to dry, and just cause, i toss them in the dry media so they don't have spots, and the brasso in the media keeps them from getting oxidized before loading.
