It doesn't work because it's prone to overheating. A lot of heat is dispersed during the normal operation of ejecting a cartridge. There's no ejection port in a caseless design, nor is there a hot brass cartridge to absorb all the heat, so it all goes directly into the chamber and sits there until it melts and causes all sorts of nasty malfunctions.
