Hornady One-Shot Corn Cob Tumbler Media 4.75 Pound

This is the best media I have found. It cleans up the brass great, and shiny with polish added. It does not stick in primer pockets as so many other brands do. I have bought cheaper, however I then have to run the finished cases through a neck size die to knock out the media that gets stuck. I use the other brands that I have purchased when I tumble with the spent primer in. Spend a few dollars more and save a lot of time.
