The 9×19mm Parabellum (also known as 9mm Luger, 9mm NATO or simply 9mm) is a rimless, centerfire, tapered firearms cartridge. Originally designed by Austrian firearm designer Georg Luger in 1901, [ 6 ] it is widely considered the most popular handgun and submachine gun cartridge due to its low cost, adequate stopping power and extensive ...
A penetration depth of 12.5 to 14 inches (320 to 360 mm) may seem excessive, but a bullet sheds velocity—and crushes a narrower hole—as it penetrates deeper, so the bullet might be crushing a very small amount of tissue (simulating an "ice pick" injury) during its last two or three inches of travel, giving only between 9.5 to 12 inches (240 ...
Terminal ballistics. Bullet parts: 1 metal jacket, 2 lead core, 3 steel penetrator. Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration.
Armour-piercing ammunition (AP) is a type of projectile designed to penetrate armour protection, most often including naval armour, body armour, and vehicle armour. [1]The first, major application of armour-piercing projectiles was to defeat the thick armour carried on many warships and cause damage to their lightly armoured interiors.
Leg wound by an expanding bullet. Expanding bullets, also known colloquially as dumdum bullets, are projectiles designed to expand on impact. This causes the bullet to increase in diameter, to combat over-penetration and produce a larger wound, thus dealing more damage to a living target. For this reason, they are used for hunting and by most ...
Armor-piercing bullets for rifle and handgun cartridges are designed to penetrate ballistic armor and protective shields intended to stop or deflect conventional bullets. Although bullet design is an important factor with regard to armor penetration, the ability of any given projectile to penetrate ballistic armor increases with increasing ...
The subsonic round is originally designed to have an optimistic effective lethal range of 400 to 530 meters and a maximum penetration of up to 10 mm of steel. Like the 5.45×39mm cartridge, the 9×39mm SP-5 features an air pocket in the tip, which increases its tendency to yaw or "keyhole" upon impact, thus increasing soft tissue damage in ...
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 ...
