It seems that my tumbling method leaves a little to be desired. After 4-5 hours in my tumbler, my brass comes out with a brushed satin type finish, not exactly what I would call polished. Here is a list of the equipment that I am currently using.
Hornady M-2 Tumbler
Frankford Arsenal corn cob media
Frankford Arsenal brass case polish
I fill the tumbler about 2/3 full with the corn cob, turn it on and add the polish as per instructions. I let the tumbler run until the polish is broken down and now longer looks like "lumped cat litter". I then add my brass, various pistol calibers, sometimes .308 or 30-06. I pre-sort my brass so I only tumble like calibers together. Yet after 4-5 hours, the brass comes out clean, still slight signs of residue in the primer pocket, but for the most part, the outside of the cases are mostly clean, but as mentioned before, I get a satin looking finish. Is this to be expected, am I tumbling too much, too less, or does my media/polish need to be changed?
