Smokeless Powder
Finnish smokeless powder Smokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to black powder. Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder. The combustion products of smokeless powder are mainly gaseous, compared to around 55% solid products (mostly potassium carbonate, potassium sulfate, and potassium sulfide) 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. Despite its name, smokeless powder is not completely free of smoke; while there may be little noticeable smoke from small-arms ammunition, smoke from artillery fire can be substantial. Invented in 1884 by Paul Vieille, the most common formulations are based on nitrocellulose, but the term was also used to desc ...

Chlorate
Chlorate is the common name of the anion, whose chlorine atom is in the +5 oxidation state. The term can also refer to chemical compounds containing this anion, with Chlorate#Compounds (salts), chlorates being the salt (chemistry), salts of chloric acid. Other Chlorate#Other oxyanions, oxyanions of chlorine can be named "chlorate" followed by a Roman numeral in parentheses denoting the oxidation state of chlorine: e.g., the ion commonly called perchlorate can also be called chlorate(VII). As predicted by VSEPR, valence shell electron pair repulsion theory, chlorate anions have trigonal pyramid (chemistry), trigonal pyramidal structures. Chlorates are powerful oxidizing agent, oxidizers and should be kept away from organics or easily oxidized materials. Mixtures of chlorate salts with virtually any combustible material (sugar, sawdust, charcoal, organic solvents, metals, etc.) will readily deflagrate. Chlorates were once widely used in pyrotechnics for this reason, though their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Action (firearms)
In firearms terminology, an action is the functional mechanism of a breechloading firearm that handles (loads, locks, fires, extracts, and ejects) the ammunition cartridges, or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all those are single-shot firearms with a closed off breech with the powder and projectile manually loaded from the muzzle. Instead, the muzzleloader ignition mechanism is referred to as the ''lock'' (e.g. matchlock, wheellock, flintlock, and caplock). Actions can be categorized in several ways, including single action versus double action, break action versus lever-action, pump-action, bolt-action, among many other types. The term action can also include short, long, and magnum if it is in reference to the length of the rifle's receiver and the length of the bolt. The short action rifle usually can accommodate a cartridge length of or smaller. The long action rifle can accommodate a cartridge of , ...

Breech-loading
A breechloader is a firearm in which the user loads the ammunition from the breech end of the barrel (i.e., from the rearward, open end of the gun's barrel), as opposed to a muzzleloader, in which the user loads the ammunition from the ( muzzle) end of the barrel. The vast majority of modern firearms are generally breech-loaders, while firearms made before the mid-19th century were mostly smoothbore muzzle-loaders. Only a few muzzleloading weapons, such as mortars, rifle grenades, some rocket launchers, such as the Panzerfaust 3 and RPG-7, and the GP series grenade launchers, have remained in common usage in modern military conflicts. However, referring to a weapon explicitly as breech-loading is mostly limited to weapons where the operator loads ammunition by hand (and not by operating a mechanism such as a bolt-action), such as artillery pieces or break-action small arms. Breech-loading provides the advantage of reduced reloading time because it is far quicker to load ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sharpshooter
A sharpshooter is one who is highly proficient at firing firearms or other projectile weapons accurately. Military units composed of sharpshooters were important factors in 19th-century combat. Along with " marksman" and "expert", "sharpshooter" is one of the three marksmanship badges awarded by the United States Army and the United States Marine Corps. The United States Navy and the United States Coast Guard use a ribbon with an attached "S" device to note a sharpshooter qualification. Military sharpshooter history American Revolutionary War and War of 1812 Some of the earliest mentions of rifling and sharpshooting units in the United States originate during around the American Revolutionary War and the War of 1812. During the 1777 battles of Saratoga, Continental Army officer Benedict Arnold strategically arranged for sharpshooter units to target enemy officers and artillery units. All such sharpshooters units were disbanded following the war's end in 1783, but they wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martini–Henry
The Martini–Henry is a breech-loading single-shot rifle with a lever action that was used by the British Army. It first entered service in 1871, eventually replacing the Snider–Enfield, a muzzle-loader converted to the cartridge system. Martini–Henry variants were used throughout the British Empire for 47 years. It combined the dropping-block action first developed by Henry O. Peabody (in his Peabody rifle) and improved by the Swiss designer Friedrich von Martini, combined with the polygonal rifling designed by Scotsman Alexander Henry. Though the Snider was the first breechloader firing a metallic cartridge in regular British service, the Martini was designed from the outset as a breechloader and was both faster firing and had a longer range. The Martini–Henry was copied on a large scale by North-West Frontier Province gunsmiths. Their weapons were of a poorer quality than those made by Royal Small Arms Factory, Enfield, but accurately copied down to the proof ma ...
