As far at "metal" casing go, most of the common and easily available obviously would react to detectors. Wonder if manganese reacts, and if not, if it could survive the explosive pressure of the propellant? hmmmYes, I know. But might be interesting to see someone try. Like one of those firearm fail videos that float around Youtube. Maybe something in a carbon fiber? Would obviously be subsonic, short range....*heads to the lab*
