Just wondering what kind of additive you guys like to use with your media.. I have used the Hornady, Cabelas brand and Iosso.. I just tried th Iosso and wasnt really to impressed. It seemed to leave a waxy residue on the cases after tumbling. So far I really like the results of the hornady mixed with Lyman Tufnut. After a few hours you get a really nice shine to your cases.
