The .500/.465 (3&1/4") Nitro Express was introduced by Holland & Holland of England to
answer the demand for a cartridge  more powerful then the 375 H&H Magnum
(375 Holland&Holland Magnum) . At close to 5,000 foot pounds of energy this cartridge has
as much energy at 200 yards as the 375 H&H Magnum has at the muzzle.
