Experimental cartridge by Paul van Hee that were made for him in Spain, but the maker is not known. This is the 9 mm /.45 Long case version – the cartridge having the basic case dimensions of the .45 Auto cartridge, but with a longer, thicker case (case length 0.95″ approximate – 24.15 mm), and an extreme bevel at the case mouth and holding a 9 mm GMCS bullet. It was also discussed HERE.
