The .45 ACP (Automatic Colt Pistol), also known as .45 Auto, .45 Automatic, or 11.43×23mm [1] is a rimless straight-walled handgun cartridge designed by John Moses Browning in 1904, for use in his prototype Colt semi-automatic pistol.
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).
In this instance, heavier bullets are loaded in standard ammunition, which reduces muzzle velocity below the speed of sound. As an example, the very common 9×19mm Parabellum standard military round is a 7.5 g (116 gr) bullet at velocities typically around 360 m/s (1,200 ft/s).

In some instances, the powder may not have even been fully burned in guns with short barrels. So, the muzzle velocity of a 2-inch (51 mm) barrel is less than that of a 4-inch (100 mm) barrel, which is less than that of a 6-inch (150 mm) barrel. Large naval guns will have high length-to-diameter ratios, ranging between 38:1 to 50:1. This length ...
This caused many existing toy gun products on the Chinese market (particularly airsoft) to become illegal overnight, as almost all airsoft guns shooting a standard 0.20 g (3.1 gr) 6 mm (0.24 in) pellet have a muzzle velocity over 76 m/s (250 ft/s), which translates to more than 0.58 J (0.43 ft⋅lbf) of muzzle energy, or 2.0536 J/cm 2 of "ratio ...
The .460 Rowland / 11.43×24mm is a rimless, straight walled handgun cartridge designed in 1997 [1] by Johnny Rowland and developed in conjunction with Clark Custom Guns as a derivative of the .45 ACP [2] with the goal of producing a cartridge which can achieve true .44 Magnum [3] ballistic performance and be fired from a semi-automatic platform.
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).
