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 ...
The modern technique (abbreviation of modern technique of the pistol) is a method for using a handgun for self-defense, originated by firearms expert Jeff Cooper. [1] The modern technique uses a two-handed grip on the pistol and brings the weapon to eye level so that the sights may be used to aim at the target.
The Mozambique Drill, [1] also known as the Failure Drill, Failure to Stop drill, or informally as "two to the body, one to the head", [2] [3] is a close-quarters shooting technique that requires the shooter to fire twice into the torso of a target (known as a double tap or hammered pair to the center of mass), and follow up with a more difficult shot to the head that, if properly placed ...
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. [1]
In the open division, IPSC has a lower power factor requirement of 160 kgr·ft/s for major, while the other IPSC handgun divisions require a power factor of 170 kgr·ft/s for major. Open and revolver are also the only divisions that allows major scoring with a 9 mm bullet diameter (the other handgun divisions require a 10 mm bullet diameter).

Once discharged from the weapon, the bullet's energy decays throughout its flight, until the remainder is dissipated by colliding with a target (e.g. deforming the bullet and target).
