The .600 Nitro Express is a slightly tapered walled, rimmed, centerfire rifle cartridge designed for use in single-shot and double rifles. [4]The cartridge fires a .620 in (15.7 mm) diameter, 900 gr (58 g) projectile with three powder loadings: the standard being 100 gr (6.5 g) of cordite at a muzzle velocity of 1,850 ft/s (560 m/s); a 110 gr (7.1 g) loading which generates a muzzle velocity ...
Typical cyclic rates of fire are 600–1100 rpm for assault rifles, 400–1400 rpm for submachine guns and machine pistols, and 600–1,500 rpm for machine guns. M134 Miniguns mounted on attack helicopters and other combat vehicles can achieve rates of fire of over 100 rounds per second (6,000 rpm).
This cartridge was intended to fire the largest bullet able to fit in the CZ-550, [2] and was designed specifically for the purpose of killing an elephant. The CZ-550 can fit two cartridges, with slight alterations. The .600 Overkill fires a 900-grain (58 g) bullet at more than 2,400 ft/s (730 m/s),
This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).
With a fire rate of 600-1000 rounds per minute, automatic rifles increased the amount of ammo a soldier had to carry. However, the ammo was much heavier (393 gr (25.4 g) for 7.62 x 51 round compared to 160 gr (10.4 g) for .45 ACP), effectively limiting the ammo load.
The hollow point made the express bullet lighter, faster, and disabled thin-skinned animals more quickly than a solid bullet, at the expense of penetration power and bullet sturdiness. [ 1 ] The term express was first applied to hunting rifles and ammunition beginning in the mid-19th century, to indicate a rifle or ammunition capable of higher ...

The Zeliska fires a 900 grain (58.32 g) .600 Nitro Express slug at 1,516 ft/s (462 m/s, 1,663.2 km/h), compared to the 1,850-2,050 ft/s regulation level velocities typical of 28” barrel rifles chambered in the cartridge. [3] The cost of a Zeliska revolver is $17,316. Each .600 Nitro Express round costs $40, making this gun very expensive to fire.
