So I asked a while back about tumblers and I picked up a harbor freight rock tumbler and some stainless steel pins. Let's just say the results were better than expected. Trial run I did about 50 pieces of 30.06 range brass I picked up here and there. Some were green and black so I figured it may get them a little better but after 1hr in the tumbler with a little lemishine they look great even the primer pockets are clean. I'm happier than a puppy with 2 peckers.

It isn't necessary to see a good tackle...you can hear it.
