The .470 Capstick is a rifle cartridge created by Col. Arthur B Alphin from A-Square in 1990, named after writer and hunter Peter Hathaway Capstick.[1] It is based on a .375 H&H Magnum case blown out and necked to accept a .475 inch (12 mm) bullet. With 500 grain (32 g) bullets, it can achieve 2400 feet per second (730 m/s) muzzle velocity from a 26" barrel.
