XLNT! Best info I've seen. I was just about to buy some stainless media but after reading your post have decided that it would be too expensive and a lot more trouble for my 38/357/45ACP reloading than it is worth. I get good results (evenone thinks my reloads look new) from using the ultrasonic and then the vibrator and it only takes a couple of hours total so I better stick with what I have. Thanks for the great, clear explanation.
