I have not. Was actually about to order Brass Juice to give it a shot and had a big boretech order i needed to make so added it on to try it. Turns out its legit.
I tumble with SS for 45min-1hr. But I’ve done some batches up to 6hrs with no ill effects. So there must be some other variable that is causing problems for other people. Too little media? Water? Too much brass?
30 min with pin style SS media is all I do with two teaspoon of dish soap and a sprinkle of lemishine.
Looks new with clean primer pockets.
Some claim that dry media doesn't get stuck in cases. I guess it depends on the media, because the ones I've just, I had to use a toothpick to clear out the flash holes and some cases the pickets too.
The only thing I use the wet tumbling for is range pick up brass that is so tarnished the dry vibratory walnut shell cleaner won't work on. A few hours in the water/lemishine and SS pins and it looks like new.
