I'm above my head on this one and felt that the wisdom of experience on this board needed to be consulted.

A friend and I ventured into reloading for personal use and he came up with some bags of Black Diamond Slag Abrasive for using in our vibrating case cleaner. I wasn't convinced but we tried some on about a thousand 9mm cases. It really cleans them, but leaves a brushed brass effect, which means to me that the media may be too abrasive. To see the stuff I'm talking about, click HERE.

Opinions are appreciated and thanks in advance.

Too abrasive is my thoughts.

I agree. I also don't like the finish on the brass when it's been to harshly polished. I just use the standard corn cob media.

I have thought about maybe mixing in some walnut with the corn cob, but no current need. I also got a bunch for free a while back, so I'm set.

Corn cob or walnut. Nothing more abrasive. There is a new stainless steel media that may have possibilities.

black beauty is about the most abrasive media for sandblasting. definatly to abbrasive for tumbling. walnut will clean the brass well and corn cob with a dab of polish will make it shine.

Thank you for the information . . . my bud and I continuously look for opportunities to prove the other wrong so this is excellent!!

I appreciate the responses.

with a thumlers tumbler model B(rock polisher) the SS media is THE best I have seen!! Cleans the brass inside and out, including the primer pockets, and really makes the brass shine brighter than new.

if you have a vibratory tumbler just get a bag of lizard bedding at the pet store.

The Tumlers Tumbler is pretty aggressive. I wonder what SS tumbling shot does to brass wall thickness over time? Just a question, I just wonder.

I use walnut. What the heck is lizard bedding?
