The official ruling is that any target made from clay or any Clay Target designed for use as a Shotgun Target are not authorized targets for PCC or IPSC Rifle competition as per rule 4.4.1
4.4.1 Frangible targets, such as tiles, may be used as scoring targets, but not as no-shoots, in IPSC Pistol Calibre Carbine matches.
