Cartridge (firearms)A cartridge or a round is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (usually either smokeless powder or black powder) and an ignition device (primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for the practical purpose of convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often informally used to refer to a complete cartridge, the correct usage only refers to the projectile.
BulletA bullet is a kinetic projectile, a component of firearm ammunition that is shot from a gun barrel. They are made of a variety of materials, such as copper, lead, steel, polymer, rubber and even wax; and are made in various shapes and constructions (depending on the intended applications), including specialized functions such as hunting, target shooting, training, and combat. Bullets are often tapered, making them more aerodynamic. Bullet size is expressed by weight and diameter (referred to as "caliber") in both imperial and metric measurement systems.
Primer (firearms)In firearms and artillery, the primer (ˈpraɪmər) is the chemical and/or device responsible for initiating the propellant combustion that will propel the projectiles out of the gun barrel. In early black powder guns such as muzzleloaders, the primer was essentially the same chemical as the main propellant (albeit usually in a finer-powdered form), but poured into an external flash pan, where it could be ignited by an ignition source such as a slow match or a flintlock, though some muzzleloaders have primers like cap gun caps.
SwagingSwaging (ˈsweɪdʒɪŋ) is a forging process in which the dimensions of an item are altered using dies into which the item is forced. Swaging is usually a cold working process, but also may be hot worked. The term swage may apply to the process (verb) or to a die or tool (noun) used in that process. The term "swage" comes from the Old French term souage, meaning "decorative groove" or "ornamental moulding". Swages were originally tools used by blacksmiths to form metal into various shapes too intricate to make with a hammer alone.
.38 SpecialThe .38 Special, also commonly known as .38 S&W Special (not to be confused with .38 S&W), .38 Smith & Wesson Special, .38 Spl, .38 Spc (pronounced "thirty-eight special"), or 9x29mmR is a rimmed, centerfire cartridge designed by Smith & Wesson. The .38 Special was the standard service cartridge for the majority of United States police departments from the 1920s to the 1990s. It was also a common sidearm cartridge used by United States military personnel in World War I, World War II, the Korean War, and the Vietnam War.
Rifle cartridgeA rifle cartridge is a firearm cartridge primarily designed and intended for use in a rifle/carbine, or machine gun. Fully powered cartridge A full-powered cartridge is a rifle cartridge used interchangeably between service rifles, sniper rifles, and general purpose machine guns. It is a retronym for rifle cartridges used prior to and during World War II. They are primarily used today in general purpose machine guns, designated marksman rifles, and sniper rifles.
Centerfire ammunitionA centerfire cartridge is a firearm metallic cartridge whose primer is located at the center of the base of its casing (i.e. "case head"). Unlike rimfire cartridges, the centerfire primer is typically a separate component seated into a recessed cavity (known as the primer pocket) in the case head and is replaceable by reloading. Centerfire cartridges have supplanted the rimfire variety in all but the smallest cartridge sizes. The majority of today's handguns, rifles, and shotguns use centerfire ammunition, with the exception of some .
Blank (cartridge)A blank is a firearm cartridge that, when fired, does not shoot a projectile like a bullet or pellet, but generates a muzzle flash and an explosive sound (muzzle report) like a normal gunshot would. Firearms may need to be modified to allow a blank to cycle the action, and the shooter experiences less recoil with a blank than with a live round. Blanks are often used in prop guns for shooting simulations that have no need for ballistic results, but still demand light and sound effects, such as in historical reenactments, special effects for theatre, movie and television productions, combat training, for signaling (see starting pistol), and cowboy mounted shooting.
GlockGlock (stylized as GLOCK) is a brand of polymer-framed, short recoil-operated, locked-breech semi-automatic pistols designed and produced by Austrian manufacturer Glock Ges.m.b.H. The firearm entered Austrian military and police service by 1982 after becoming the top performer in reliability and safety tests. Glock pistols have become the company's most profitable line of products, and have been supplied to national armed forces, security agencies, and police forces in at least 48 countries.
HandgunA handgun is a firearm designed to be usable with only one hand. It is distinguished from a long gun (i.e. rifle, shotgun, submachine gun, or machine gun) which needs to be held by both hands and braced against the shoulder. The two most common types of handguns are revolvers and semi-automatic pistols, although other types such as derringers and machine pistols also see infrequent usage. Before commercial mass production, handguns were often considered a badge of office—comparable to a ceremonial sword—as they had limited utility and were more expensive than the long guns of the era.
