I've had very good results with a 50/50 mix of walnut & corn cob.
I add about 2 teaspoons of Flitz metal polish to the media when I first make it up.
The Flitz not only gives an nice shine, but also has some kind of anti-tarnish agent in it which seems to keep the cases bright over longer periods of time.
Note according to the Flitz web site, only the paste form has the anti-tarnish agent; the liquid does not. Premix the paste in about 1/2 cup of media using a spoon to mash into the media. When well mixed, add the 1/2 cup to the other media in your tumbler. If you don't premix, the paste will tend to ball up instead of being evenly distributed throughout the media.
