I was needing to change out my walnut stuff and saw a post on another site. Picked up a 5# bag of uncooked white rice at Wally world for $2.93.2.5# is a perfect match to my midway tumbler. I followed the guys recipe and mixed 1 oz kit car wax with 1 oz rubbing alcohol and slowly added it to the tumbler.Let it run about 1/2 hour and the alcohol disapated pretty good.Have now done 4 batches of brass and they come out beautiful in probably less time than walnut. The big plus for me is there is way way less dust when you are done. The rice also comes out of the shells better when shaking through the sifter. Not saying its a miracle but I find it better and pretty cheap.
