Going thru some brass a neighbor gave me I found an odd round. The brass has U.S.C.Co. 38S&W stamped on it. The primer also has US stamped on it. It didn't have powder but something hard of the consistancy of charcoal and on top of that on the top 1/16" a whiteish sealer of some kind that was like dried out caulk and finished with a roll crimp. I've no idea what this is, something legit or it might have been someones experiment. Had no intention of shooting it, just curious.
Thanks, Steve
