As a supplement to my original post, "Can your media do this?? The ultimate challenge", I decided to see how conventional corn cob would fare against that skanked out brass. This is what 2 handfuls looked like after 12 hrs of vibratory tumbling in corn cob and some polish:
Needless to say, not too impressive. Bluntly stated, these results suck balls. Not only are the cases ugly as a turd, but they cannot be used in this condition. The surface is still rough. I won't even bother checking inside the cases, but I would estimate that there is a lot of lost case capacity due to oxidation buildup. In addition, I tumbled in corn cob for 12 hrs, vs 6 hrs with the steel media, and it still couldn't even come close.
I performed this test to see how unique the ability of steel media is. My results have further reinforced my claim that tumbling with steel media is best method out there today as a whole, in terms of cost, time, production, efficiency, results, and utility.
