I have that system. Got it from the site you have. I would not go back to regular tumbling. Was at the pistol range and picked up some brass that had to have been out there for a couple of years just to try it. I couldnt beleve what it looked like when it was done. Better than new. I do brass from 223 up to 50BMG and have had great success. would recomend this to anyone.
Best part is dont have to clean primer pockets any more.
