Purchased this media for use with a brass tumbler.Did a good job and as it was designed to do.Packaging was a bit on the poor side. Was put into a plastic bag (good), but the bag was not sealed very well.But overall, the product performed as designed. Did a good job.One other thing, was that in a world of online sales, free shipping has become the norm. I was surprised when I saw the total cost with shipping for this item. Still, you cant expect every retailer to bear the cost of shipping. Just caught me off guard.

It doesn't plug the primer hole, and it works well..

Small enough to clean ammo primer pockets if given enough time. Best feature - its about like coarse ground pepper, and is not large enough to get stuck in pockets. Just falls right out, no primer pocket picking needed.
