Based on the old black-powder .500/450, the .500/450 Magnum Nitro Express was introduced by Holland & Holland for their single shot and double rifles during the late 1890s. It fires a .458-inch (11.6 mm) 480-grain (31 g) projectile at over 2,100 feet per second (640 m/s) to generate in excess of 5,000 foot-pounds force (6.8 kJ) of muzzle energy.
Performance
Ballistic performance of the .500/450 NE is very similar to the .450 Nitro Express cartridge.[1] Like other .458 caliber British hunting cartridges, it has low pressure making it a good choice for any hot climate.
