I find that walnut cleans more crud but leaves a slightly dull finish when compared with cases tumbled in corn cob. For a real bright, jewelry like shine I use the walnut first to clean and then corn cob to polish. About an hour in my RCBS Sidewinder on the 'nut shell'. Size, trim, clean pockets, etc, and then 2-3 hours in the cob with Dillon polish. To keep them that way I wear gloves so I don't end up with tarnish smudges on the cases from hand oils and salts.
