It is among the largest practical handgun calibers in use, featuring a .452 inches (11.5 mm) diameter bullet. With well-made expanding ammunition, a .452 bullet often expands to .70 caliber or larger. With a 9 mm Luger cartridge, the normal .355 bullet may expand to .50 or larger. Theoretically, a larger caliber should cause slightly more ...
Ballistics by the Inch (often called BBTI) was a project to test the performance characteristics of a variety of common handgun calibers/cartridges.The initial testing was done in 2008 and tested the velocity of 13 common handgun cartridges as it related to firearm barrel length.
The wounding potential of a bullet is often characterized in terms of its expanded diameter, penetration depth, and energy. Bullet energies for .380 ACP loads vary from 190 to 294 ft⋅lbf (258 to 399 J). [12] The table below shows common performance parameters for several .380 ACP loads.
The .40 S&W (10.2×22mm) is a rimless pistol cartridge developed jointly by American firearms manufacturers Smith & Wesson and Winchester in 1990. [3] The .40 S&W was developed as a law enforcement cartridge designed to duplicate performance of the Federal Bureau of Investigation's (FBI) reduced-velocity 10mm Auto cartridge which could be retrofitted into medium-frame (9 mm size) semi ...
This cartridge is compatible with handguns chambered for the .500 S&W Magnum and fires a 350-grain (23 g) bullet at 1,250 feet per second (380 m/s). [11] These low-recoiling alternatives to the full-power .500 S&W Magnum significantly reduce felt recoil, which is especially noticeable in the shorter 4-inch-barrel (100 mm) handguns.
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).
The bullet must also engage the rifling without damaging or excessively fouling the gun's bore and without distorting the bullet, which will also reduce accuracy. Bullets must have a surface that forms this seal without excessive friction. These interactions between bullet and bore are termed internal ballistics. Bullets must be produced to a ...
9mm Major is a wildcat cartridge of the 9mm Luger specifically for competition pistols designed to handle very high pressure. It is used in practical shooting competitions like International Practical Shooting Confederation (IPSC) and United States Practical Shooting Association (USPSA) to achieve a "Major" power factor, which earns more points for hits in specific zones on paper targets ...
