Well not really, I bought a 50lb bag of walnut sand blasting media (which might be the same). Anyway I was very impressed. I used to use corn cob bedding that I got from pet stores but it's a little hard to find now. I have a Lyman vibratory cleaner and I used to set a timer for 3hrs and it did a credible job. But I kept checking the walnut stuff as it was working and it cleaned everything in half the time. It actually did a much better job and I didn't have to pick corn cob pieces out the 9mm cases which is a pain. So overall if your looking for a good media at a reasonable cost (I paid $30 I think) then try this stuff. TC
