I just started tumbling cases a week ago. I'm dry tumbling 9X18 MAK in cob medium. Some cases were very cruddy, almost black, from the range. After about 4-5 hours in the tumbler they come out very smooth and shiny, but still this dark brown/black. Is this as clean as they will ever get? Are they stained or can I do something to get them to looking like brass once more?
