Christchild, I agree that the media goes inside the cases, but at this point don't think it circulates and cleans once in. You've got a point with the vibration but the media that goes in doesn't continuously circulate--it stay inside. Maybe it does vibrate enough to clean? The writers of the articles that I linked too don't think so. I'm not convinced that it does anything either but it does create another market for the manufacturers. Plus the media dust will stay inside too and coat the outside (microscopic) and contaminate the dies (unless you clean the brass)?

The ultrasonic seems to clean for sure.

How clean does the inside have to be or free from burned powder? Does a little powder residue make that much difference?
