    en.wikipedia.org/wiki/Table_of_handgun_and_rifle...

    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).

    en.wikipedia.org/wiki/.40_Super

    The .40 Super (10.2x25mm) is a powerful automatic pistol cartridge developed through the collaboration of Fernando Coelho and Tom Burczynski and introduced by Triton Cartridge in 1996.

    en.wikipedia.org/wiki/Caliber

    While modern firearms are generally referred to by the name of the cartridge the gun is chambered for, they are still categorized together based on bore diameter. [citation needed] For example, a firearm might be described as a "30 caliber rifle", which could accommodate any of a wide range of cartridges using a roughly 0.30 inches (7.6 mm) projectile; or as a "22 rimfire", referring to any ...

  8. Power factor (shooting sports) - Wikipedia

    en.wikipedia.org/wiki/Power_factor_(shooting_sports)

    In IPSC competitions all handguns must have a power factor of at least 125 kgr·ft/s (≈ 2.47 newton seconds), and therefore almost anything of 9×19mm or greater caliber will meet the minimum required power factor. The minimum power factor rule is designed to mitigate the speed and accuracy advantages of smaller calibers.

  9. Muzzle velocity - Wikipedia

    en.wikipedia.org/wiki/Muzzle_velocity

    In a side-by-side comparison with the .50 BMG (43 g), the 15 gr (1 g) titanium round of any caliber released almost 2.8 times the energy of the .50 BMG (1 g at 10 000 m/s = 50 000 joules), with only a 27% mean loss in momentum. Energy, in most cases, is what is lethal to the target, not momentum. [8]
