.45 Raptor

11.5x46mm or .45 Raptor is a large bore rifle cartridge designed by Arne Brennan for use in semi automatic battle rifles (primarily AR-10). Besides offering .45-70 performance even with shorter barrels, it does not impair .308 magazine capacity. As a downside, being a .452 caliber cartridge, it can't use .458 bullets "as is", they would require resizing work.
