I just finished tumbling my first batch of brass. Its all 9mm. Actually its a vibrating unit. I am using the media that came with it and Frankford Arsenal brass polish by the directions on the bottle. Its been going for 3 hours, but some of the cases are still pretty tarnished. They may be some of the range brass that Ive been picking up lately. Id say 1 to 2 of every 10 is still tarnished to a large degree. Has this brass been permanently tarnished or would more time in the vibrator do the trick? I dont expect the brass to come out perfect, but the majority are bright and shiny and the other 15-20% look pretty lousy.
