Half Cock
Half-cock is when the position of the hammer (firearm), hammer of a firearm is partially—but not completely—cocked. Many firearms, particularly older firearms, had a notch cut into the hammer allowing half-cock, as this position would neither allow the gun to fire nor permit the hammer-mounted firing pin to rest on a live percussion cap or cartridge (firearm), cartridge. The purpose of the half-cock position has variously been used either for loading a firearm, as a safety (firearm), safety mechanism, or for both reasons. The still commonly used English expression of "Wiktionary:go off half-cocked, going off half-cocked" derives from failing to complete the cocking action, leading to the weapon being unable to fire. This is often used to describe someone acting prematurely, as in the case of one preparing to shoot their weapon without having set the firearm into "full-cock" position. Early examples Early flintlocks had required a half-cock position to primer (firearm), pri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Colt 1851 Navy Revolver
The Colt Revolving Belt Pistol or Navy Pistol, sometimes erroneously referred to as "Colt Revolving Belt Pistol of Naval Caliber" or "of Navy Caliber" (Naval is heavy gun and Navy Size Caliber was termed later for another Colt model), is a cap and ball revolver that was designed by Samuel Colt between 1847 and 1850. Colt first referred to this Revolver as the Ranger Size model, and then Revolving Belt, but the designation "Navy" quickly took over. After the Civil War, revolvers using fixed metallic cartridges came into widespread use. The Colt Navy remained in production until 1873, being replaced in the Colt line with what would become one of the manufacturer's most famous handguns, the Colt Single Action Army (also known as the ''Peacemaker'' and ''Colt 45''). Total production numbers of the Colt 1851 Navy Revolver were exceeded only by the Colt Pocket models in concurrent development, and numbered some 215,000 domestic units and about 42,000 produced in the Colt London Armory. ...

Shearing (physics)
In continuum mechanics, shearing refers to the occurrence of a shear strain, which is a deformation of a material substance in which parallel internal surfaces slide past one another. It is induced by a shear stress in the material. Shear strain is distinguished from volumetric strain. The change in a material's volume in response to stress and change of angle is called the angle of shear. Overview Often, the verb ''shearing'' refers more specifically to a mechanical process that causes a plastic shear strain in a material, rather than causing a merely elastic one. A plastic shear strain is a continuous (non-fracturing) deformation that is irreversible, such that the material does not recover its original shape. It occurs when the material is yielding. The process of shearing a material may induce a volumetric strain along with the shear strain. In soil mechanics, the volumetric strain associated with shearing is known as Reynolds' dilation if it increases the volume, or c ...

Spring (device)
A spring is an elastic object that stores mechanical energy. In everyday use the term often refers to coil springs, but there are many different spring designs. Modern springs are typically manufactured from spring steel, although some non-metallic objects like the bow are also springs. When a conventional spring, without stiffness variability features, is compressed or stretched from its resting position, it exerts an opposing force approximately proportional to its change in length (this approximation breaks down for larger deflections). The ''rate'' or ''spring constant'' of a spring is the change in the force it exerts, divided by the change in deflection of the spring. That is, it is the gradient of the force versus deflection curve. An extension or compression spring's rate is expressed in units of force divided by distance, for example or N/m or lbf/in. A torsion spring is a spring that works by twisting; when it is twisted about its axis by an angle, it produces a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shooting Times
''Shooting Times and Country Magazine'', more commonly known as the ''Shooting Times'', is a British shooting, fieldsports, and conservation magazine, published by Future plc. The magazine also features articles on fishing, deer stalking, gamekeeping, gundogs, cookery, and conservation. History ''Wildfowler's Shooting Times and Kennel News'', the publication's original title, was first published in September 1882 and has not missed a single edition since. Lewis Clement was the first editor. Throughout its history, ''Shooting Times'' has offered a forum for debate in the shooting world—famously in the 26 October 1907 issue, Stanley Duncan, (a long-term contributor to the magazine) wrote in with a request: "Sir, I have been asked to suggest a Wildfowlers's Association, to which you, Mr Editor, might give some assistance by permitting your paper to be the organ through which proposals might be considered and views obtained?" The name of the association born out of the ensuing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chamber (firearms)
In firearms, the chamber is the cavity at the back end of a breechloader's barrel or cylinder, where the cartridge is inserted before being fired. The rear opening of the chamber is the breech, and is sealed by the breechblock or the bolt. Function Rifles and pistols generally have a single chamber integral to their barrels, but revolvers have multiple chambers in their cylinder, and no chamber in their barrel. Thus, rifles and pistols can usually still be fired with the magazine removed as long as a cartridge is inserted into the chamber, while a revolver cannot be fired at all with its cylinder swung out. The act of ''chambering'' a cartridge means the insertion of a round into the chamber, either manually or through the action of the weapon, e.g., pump-action, lever-action, bolt action, or Autoloading operation generally in anticipation of firing the weapon, without need to "load" the weapon upon decision to use it (reducing the number of ''actions'' needed to disch ...

Winchester Model 94
The Winchester Model 1894 rifle (also known as the Winchester 94 or Model 94) is a lever-action repeating rifle that became one of the most famous and popular hunting rifles of all time. It was designed by John Browning in 1894 and originally chambered to fire two metallic black powder cartridges, the .32-40 Winchester and .38-55 Winchester. It was the first rifle to chamber the smokeless powder round, the .30 WCF (Winchester Center Fire, in time becoming known as the .30-30) in 1895. In 1901 Winchester created the new .32 Winchester Special caliber with production of rifles starting in 1902. The 1894 was produced by the Winchester Repeating Arms Company through 1980 and then by U.S. Repeating Arms under the Winchester brand until they ceased manufacturing rifles in 2006. Reproductions are being made by the Miroku company of Japan and imported into the United States by the Browning Arms company of Morgan, Utah. The Model 1894 has been referred to as the "ultimate lever-acti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rifle
A rifle is a long-barreled firearm designed for accurate shooting, with a barrel that has a helical pattern of grooves ( rifling) cut into the bore wall. In keeping with their focus on accuracy, rifles are typically designed to be held with both hands and braced firmly against the shooter's shoulder via a buttstock for stability during shooting. Rifles are used extensively in warfare, law enforcement, hunting, shooting sports, and crime. The term was originally ''rifled gun'', with the verb ''rifle'' referring to the early modern machining process of creating groovings with cutting tools. By the 20th century, the weapon had become so common that the modern noun ''rifle'' is now often used for any long-shaped handheld ranged weapon designed for well-aimed discharge activated by a trigger (e.g., personnel halting and stimulation response rifle, which is actually a laser dazzler). Like all typical firearms, a rifle's projectile (bullet) is propelled by the contained def ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, it is correctly used only to refer to the projectile. Cartridges can be categorized by the type of their primers – a small charge of an impact- or electric-sensitive chemical mixture that is located: at the center of the case head (centerfire); inside the rim ( rimfire); inside the walls on the fold of the case base that is shaped like a cup (cupfire, now obsolete); in a sideways projection that is shaped like a pin (pinfire, now obsolete); or a ...

Lever Action
The toggle-link action used in the iconic Winchester Model 1873 rifle, one of the most famous lever-action firearms Lever-action is a type of action for repeating firearms that uses a manually operated cocking handle located around the trigger guard area (often incorporating it) that pivots forward to move the bolt via internal linkages, which will feed and extract cartridges into and out of the chamber, and cock the firing pin mechanism. This contrasts to other type of repeating actions such as the bolt-action, pump-action, semi-automatic, or automatic/selective-fire actions. A firearm using this operating mechanism is colloquially referred to as a levergun. Most lever-action firearms are rifles, but some lever-action shotguns and a few pistols have been made. The Winchester Model 1873 rifle is one of the most famous lever-action firearms, but many manufacturers (notably Henry and Marlin) also produce lever-action rifles. Even Colt's Mfg. Co. produced the 6403 lever-action C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Rifleman
''American Rifleman'' is a United States-based monthly shooting and firearms interest publication, owned by the National Rifle Association (NRA). It is the 33rd-most-widely-distributed consumer magazine and the NRA's primary magazine. The magazine has its headquarters in Fairfax, Virginia. History Arthur Corbin Gould, an avid shooter and member of the Massachusetts Rifle Association, published ''The Rifle'' in 1885 as an effort to focus discussion on the sport of rifle shooting. ''The Rifle'' later changed its title to ''Shooting and Fishing'' in 1888, branching out into other outdoor sports. In 1894, while the magazine was titled ''Shooting and Fishing'', Gould attended the National Rifle Association matches held at Sea Girt and was impressed with the level of competition, leading him to write several editorials urging the public to join. This call eventually led to the revitalization of the National Rifle Association and established a Board of Directors to help manage the ...
