New for 2010! Do you really need a tumbler that fits 600 9mm cases? Just think about it and think about how much money you could save buying our new SR737 Tumbler Nano, how much media you would save and most important the electricity that a bigger and unnedeed tumbler will consume. The tumbling action of the SR737 Tumbler Nano is as good as a bigger one but comes with so many advantages that the small money you will pay for it you will get it back after few times you used it.
