Hammerhead,
I'm with you. I must not be running my tumbler long enough to clean the inside. I get good results on the outside. Someone posted they actually get the primer pocket somewhat clean by running a long time. But, I'm ready to start up my ultra-sonic cleaner now that I know it has the heating feature. I want to check the results against some 45 Colt I'm tumbling now.
Whisper300 - Great idea with the timer. Glad I thought of it.
