Will rice keep from breaking up into small particles if used in a vibratory tumbler? Would hate to find rice "flour" in my tumbler after an all-night session of tumbling. Have been using walnut and corn media exclusively and dump my media for new about every six months. The cost savings was never an issue when buying media.Yes, heard the same thing and tried it out. NO apprecable difference than straight corn cobb. Kept getting rice in the primer hole and needed to check each case before sizing. Just my opinion, but it is not worth the extra work.
