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.
[edit] Overview
Although it is not very flat shooting because of slow velocities, it is flat enough for use out to 250 yards (230 m). It transmits an extreme amount of power at over 6,000 ft·lbf (8,000 J) and is designed for use on dangerous game out to 200 yards.[1] Like other large cartridges, the high energy performance is accompanied by a large amount of recoil.
The Capstick is very similar in dimension to the .470 Ackley Magnum, but where the Ackley uses a 600-grain (39 g) bullet, the Capstick uses a lighter 500-grain (32 g) bullet for a better trajectory.[1]
