[QUOTE="KSAv8r, post: 2502967, member: 86098"] I see several posts using a polishing compound along with corn cob or walnut shells in their vibratory tumbler. FWIW.....most of the polishing compounds have a very fine grit that speeds the cleaning process. Unless US or other liquid cleaning method is used after tumbling, this grit adheres to carbon residue left inside of the case . When a round is fired, some of this grit is forced down the barrel. The next round that is fired will embed the grit into the barrel and also cause premature throat and barrel erosion. Some of our competitive BR shooters use cases tumbled with polishing compound to speed barrel break-in but discontinue this practice after approximately 100 rounds. YMMV. [/QUOTE]
