I tried rice today, definitely doesn't shine the brass up, it looks better but doesn't shine like walnut media, I think I'm gonna go with that Zilla walnut stuff for pet lizards that bowhunter is using, looked up reviews on Amazon and many reloaders are using it with great results, most saying it's a little more aggressive than your typical name brand stuff. Name brand stuff works good for me but they are charging over 20 bucks for a small amount, I can get 33 pounds of the Zilla stuff for about 40 with shipping and tax. I don't worry about cleaning the stainless steel media out of my cases, I just shoot it and it cleans out my barrel really nice, ok, don't do that, bad joke.
