The .500 Nitro Express is a .510 caliber big bore hunting cartridge designed for use in single-shot and double-barrel rifles. The cartridge was designed for use against large dangerous game species in Africa and India. The .500 Nitro Express provided a leap in stopping power and performance over its black powder rivals. The typical .500 Nitro Express generates about 20% more energy than the .450 Nitro Express cartridge and is considered to be superior to the smaller caliber Nitro Express cartridges in killing power. The 570 grain projectile has excellent sectional density which is required for work against dangerous game out to 110 yd and provides adequate penetration for the hunting of thick skinned dangerous game. The 570 grain solid projectile is used mainly elephant but was also used in some situations for Cape buffalo and rhinoceros when the extra penetration provided by these non-expanding projectiles was necessary. Unlike some of the more modern cartridges such as the .460 Weatherby, the .500 Nitro Express it is not considered too over powered for use against the big cats.
