A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and used by an individual. The term is legally defined further in different countries.
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon, and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines, tunnels, and roads.
Cordite is a family of smokeless propellants developed and produced in Britain since 1889 to replace black powder as a military firearm propellant. Like modern gunpowder, cordite is classified as a low explosive because of its slow burning rates and consequently low brisance. These produce a subsonic deflagration wave rather than the supersonic detonation wave produced by brisants, or high explosives. The hot gases produced by burning gunpowder or cordite generate sufficient pressure to propel a bullet or shell to its target, but not so quickly as to routinely destroy the barrel of the gun.
A cartridge, also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile, a propellant substance 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 convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often used to refer to a complete cartridge, the correct usage only refers to the projectile.
A muzzleloader is any firearm in which the user loads the projectile and the propellant charge into the muzzle end of the gun. This is distinct from the modern designs of breech-loading firearms, in which user loads the ammunition into the breech end of the barrel. The term "muzzleloader" applies to both rifled and smoothbore type muzzleloaders, and may also refer to the marksman who specializes in the shooting of such firearms. The firing methods, paraphernalia and mechanism further divide both categories as do caliber.
Internal ballistics, a subfield of ballistics, is the study of the propulsion of a projectile.
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 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, and cowboy mounted shooting. Specialised blank cartridges are also used for their propellant force in fields as varied as construction, shooting sports, and fishing and general recreation.
Smokeless powder, also referred to as gunpowder, is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to black powder. The combustion products are mainly gaseous, compared to around 55% solid products for black powder. In addition, smokeless powder does not leave the thick, heavy fouling of hygroscopic material associated with black powder that causes rusting of the barrel.
A powder is a collection of very fine particles that may flow freely when shaken or tilted.
Hang fire is an unexpected delay between the triggering of a firearm and the ignition of the propellant. This failure was common in firearm actions that relied on open primer pans, due to the poor or inconsistent quality of the powder, although modern firearms are also susceptible. The delay is usually too brief to be noticed, but can be several seconds. A hangfire should be suspected whenever a firearm fails to fire, but has not clearly malfunctioned.
Idli podi, chutney pudi, or milagai podi is a coarse spice powder, originating from the Indian subcontinent, with a mixture of ground dry spices that typically contains dried chilis, black gram, chickpeas, salt and sesame seeds. The spice mix is commonly referred to in informal speech as "gunpowder" or chutney powder. It is generally mixed with gingelly (sesame) oil or melted ghee when it is served alongside idli or dosa.
Gunpowder tea is a form of tea in which each leaf has been individually rolled into a small pellet. Its English name comes either from some resemblance of the pellets to gunpowder, or from a phrase in Chinese that phonetically resembles the word "gunpowder". This rolling method of shaping tea is most often applied either to dried green tea or to oolong tea.
Muzzle flash is the light — both visible and infrared — created by a muzzle blast, which is caused by the sudden release and expansion of high-temperature, high-pressure gases from the muzzle of a firearm during shooting. Both the blast and flash are products of the exothermic combustion of the propellant (gunpowder), and any remaining unburned powders reacting with ambient air. The size and shape of the muzzle flash is dependent on the combustion energy of propellant being used, the amount of combustible ejecta remaining, and any devices attached to the muzzle.
A black powder substitute or gunpowder substitute is a replacement for black powder (gunpowder) used in muzzleloading and cartridge firearms. Black powder substitutes have slightly different properties from gunpowder, and are subject to different restrictions. Compared to gunpowder, black powder substitutes may have reduced sensitivity as an explosive, increased efficiency as a propellant powder, different density, and/or reduced ignition efficiency.
The history of firearms begins in 10th-century China, when tubes containing gunpowder and pellet projectiles were mounted on spears to make portable fire lances, operable by one person. This was later used effectively as a shock weapon in the Siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into metal-barreled hand cannons. The technology gradually spread throughout Eurasia during the 14th century and evolved into flintlocks, blunderbusses, and other variants. The 19th and 20th centuries saw an acceleration in this evolution, with the introduction of the magazine, belt-fed weapons, metal cartridges, and the automatic firearm. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants. Most modern firearms have rifled barrels.
The following are terms related to firearms and ammunition topics.
Ammunition is the material fired, scattered, dropped, or detonated from any weapon or weapon system. Ammunition is both expendable weapons and the component parts of other weapons that create the effect on a target.
A gun is a device designed to propel a projectile using pressure or explosive force. The projectiles are typically solid, but can also be pressurized liquid, or gas. Solid projectiles may be free-flying or tethered. A large-caliber gun is also called a cannon.
Black powder cartridge refers to firearms ammunition from the period after the introduction of metallic cartridge, but prior to the wide adoption of smokeless powder. These cartridges had adopted the new technology of complete cartridges including a brass casing which held the powder charge, bullet, and primer. However, unlike almost all later firearms, these firearms used black powder as a propellant charge.
A powder measure is a device for dispensing consistent amounts of smokeless powder or black powder as charges for handloading cartridges used as small arms ammunition.
