Sand used as tumbling medium may find its way into reloading dies, get embedded in the die and scratch all the cases as they are sized. Sand may embed in the brass case and be transferred to the rifle chamber and become embedded there pitting the chamber. All tumbling media for brass cases take this into account and use media that is softer than the brass and cannot cause problems.
The industrial media as per this thread does not take into account the specific requirements of hand loading. The sand mix is for brass parts that will never see the inside of a reloading die or rifle chamber.
