I just bought a Hornady case tumbler and Lyman Turbo Tumbler Media. On the Lyman jug, "corncob green" is checked. Im looking to clean 100 45acp cases. How many hours should I let it run? I have it half full. I am trying to begin to reload. When I determine a good load, then I'll do 500 at a time. How full does it need to be?
