Re: Cleaning Shell cases.....Tumblers or ultrasonic cleaners ???
I've used all the methods and ss tumbling is light years ahead of the other two (vibratory and US) methods. The start up cost is higher, but evens out pretty quickly. The pins will last forever, and the only consumables are a little dish soap and lemishine. All the possible problems, answers can be found with a simple Google search for some long threads on how the method came about.
