Chance-dg, I found you the perfect bulk case cleaner. You can use either dry media or add liquid.

Honest, if I were needing to clean a lot of cases I'd pick one up and work out the best media and time.

Chance-dg, are you adding anything to your media? I add NuFinish car polish to mine and adjust the tumble time to achieve the level of shine desired. I've heard others use citric acid or Lemon-shine to their media. I'm not sure but I seem to remember warnings about using Brasso, or anything with ammonia in it. I've cleaned up some pretty skanky range pick-ups over the years and some spots just don't come out no matter what you use or how long your tumble it..
