Re: Tumbling with shot peening media
I'd think it would have to be pretty small media to work in the primer pockets of your brass. I'd be interested to see if it works well with traditional vibratory tumbling. If you are gonna wet tumble like the stainless steel media pins, I'd just recommend going with the pins, because it's got a proven track record. I really think the next evolution of brass cleaning is going ot be some sort of a dry process, that will work with traditional vibratory tumblers and seperators.
Good luck, let us know how it goes.
