One factor used to measure a handgun's effectiveness is penetration. The FBI's requirement for all service rounds is 12 to 18 inches (30 to 46 cm) penetration in calibrated ballistic gelatin. This generally ensures a bullet will reach the vital human organs from many angles and through many different layers and materials of clothing.
Caliber/calibre: In small arms, the internal diameter of a firearm's barrel or a cartridge's bullet, usually expressed in millimeters or hundredths of an inch; in measuring rifled barrels this may be measured across the lands (.303 British) or grooves (.308 Winchester) or; a specific cartridge for which a firearm is chambered, such as .45 ACP or .357 Magnum.
Stopping power is the ability of a weapon – typically a ranged weapon such as a firearm – to cause a target (human or animal) to be incapacitated or immobilized. Stopping power contrasts with lethality in that it pertains only to a weapon's ability to make the target cease action, regardless of whether or not death ultimately occurs.

The risk of infection is especially high due to the large area of injury and destroyed tissue. [ 20 ] Bullets from handguns are sometimes less than 300 m/s (980 ft/s) but with modern pistol loads, they usually are slightly above 300 m/s (980 ft/s), while bullets from most modern rifles exceed 750 m/s (2,500 ft/s).
The M2 Browning machine gun with a tripod weighs 58 kg (128 lb).. A heavy machine gun (HMG) is significantly larger than light, medium or general-purpose machine guns. [1] HMGs are typically too heavy to be man-portable (carried by one person) and require mounting onto a weapons platform to be operably stable or tactically mobile, have more formidable firepower, and generally require a team of ...
The gauge of a shotgun refers to how many lead spheres, each with a diameter equal to that of the bore, that amounts to one pound (454 g (1.0 lb)) in weight. In the case of a 12-gauge (18.5 mm) shotgun, it would take 12 spheres the size of the shotgun's bore to equal a pound. [ 12 ]
