.450 Rigby
The .450 Rigby is a rifle cartridge designed in 1994 by John Rigby & Co. for the hunting of large, thick-skinned dangerous game animals in Africa. The cartridge is based on the .416 Rigby necked up to accept a .458 in (11.6 mm) bullet and is intended for use in magazine rifles. The cartridge should not be confused with .450 Nitro Express which was introduced by Rigby in 1898, and is a rimmed cartridge intended for use in double rifles. History In 1993, Paul Roberts (at that time proprietor of John Rigby & Company) was on an elephant hunt in the Zambezi Valley. Both he and his professional hunter, Joseph Wright, were armed with .416 Rigby rifles. An elephant was found and shot, but due to a misjudgment in the distance, several more rounds were required to finally bring down the elephant. After this experience, Paul Roberts felt that a cartridge with a greater bullet-weight and a larger caliber, would have been more effective in that situation. Once Paul Roberts returned ...

Wildcat Cartridges
The wildcat is a species complex comprising two small wild cat species: the European wildcat (''Felis silvestris'') and the African wildcat (''F. lybica''). The European wildcat inhabits forests in Europe, Anatolia and the Caucasus, while the African wildcat inhabits semi-arid landscapes and steppes in Africa, the Arabian Peninsula, Central Asia, into western India and western China. The wildcat species differ in fur pattern, tail, and size: the European wildcat has long fur and a bushy tail with a rounded tip; the smaller African wildcat is more faintly striped, has short sandy-gray fur and a tapering tail; the Asiatic wildcat (''F. lybica ornata'') is spotted. The wildcat and the other members of the cat family had a common ancestor about 10–15 million years ago. The European wildcat evolved during the Cromerian Stage about 866,000 to 478,000 years ago; its direct ancestor was ''Felis lunensis''. The ''silvestris'' and ''lybica'' lineages probably diverged about 173,0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pistol And Rifle Cartridges
A pistol is a handgun, more specifically one with the chamber integral to its gun barrel, though in common usage the two terms are often used interchangeably. The English word was introduced in , when early handguns were produced in Europe, and is derived from the Middle French ''pistolet'' (), meaning a small gun or knife. In colloquial usage, the word "pistol" is often used to describe any type of handgun, inclusive of revolvers (which have a single barrel and a separate cylinder housing multiple chambers) and the pocket-sized derringers (which are often multi-barrelled). The most common type of pistol used in the contemporary era is the semi-automatic pistol, while the older single-shot and manual repeating pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment, and the fully automatic machine pistols are uncommon in civilian usage due to generally poor recoil-controllability and strict laws and regulations governing their manu ...

Free Recoil
Free recoil is a vernacular term or jargon for recoil energy of a firearm not supported from behind. Free recoil denotes the translational kinetic energy (''Et'') imparted to the shooter of a small arm when discharged and is expressed in joules (J), or foot-pound force (ft·lb''f'') for non-SI units of measure. More generally, the term refers to the recoil of a free-standing firearm, in contrast to a firearm securely bolted to or braced by a massive mount or wall. Free recoil should not be confused with recoil: * Free recoil is the given name for translational kinetic energy transmitted from a small arm to a shooter. * Recoil is a name given for conservation of momentum as it generally applies to an everyday event. Free recoil and firearms Free recoil, sometimes called ''recoil energy'', is a byproduct of the propulsive force from the powder charge held within a firearm chamber (metallic cartridge firearm) or breech (gunpowder firearm).

Recoil
Recoil (often called knockback, kickback or simply kick) is the rearward thrust generated when a gun is being discharged. In technical terms, the recoil is a result of conservation of momentum, as according to Newton's third law the force required to accelerate something will evoke an equal but opposite reactional force, which means the forward momentum gained by the projectile and exhaust gases ( ejectae) will be mathematically balanced out by an equal and opposite momentum exerted back upon the gun. In hand-held small arms, the recoil momentum will be eventually transferred to the ground, but will do so through the body of the shooter hence resulting in a noticeable impulse commonly referred to as a "kick". In heavier mounted guns, such as heavy machine guns or artillery pieces, recoil momentum is transferred to the Earth's surface through the platform on which the weapon is mounted. In order to bring the rearward moving gun to a halt, the momentum acquired by the gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
460 Weatherby Magnum
The .460 Weatherby Magnum is a belted, bottlenecked rifle cartridge, developed by Roy Weatherby in 1957. The cartridge is based on the .378 Weatherby Magnum necked up to accept the bullet. The original .378 Weatherby Magnum parent case was inspired by the .416 Rigby. The .460 Weatherby Magnum was designed as an African dangerous game rifle cartridge for the hunting of heavy, thick skinned dangerous game. Prior to the Weatherby's arrival, the .600 Nitro Express had been the most powerful cartridge but the .460 Weatherby Magnum eclipsed this, and was the world's most powerful commercially available sporting cartridge for 29 years until the advent of the .700 Nitro Express. The .460 launches a bullet at a chronographed velocity of from a barrel, measuring of muzzle energy.''Weatherby Guide'' 12th Ed. 1962 Cartridge history Roy Weatherby had expected the .378 Weatherby Magnum to make some headway in the African continent but believed that his cartridge was being bypassed ...

Proof (firearms)
A proof test is a form of stress test to demonstrate the fitness of a load-bearing structure. An individual proof test may apply only to the unit tested, or to its design in general for mass-produced items. Such a structure is often subjected to loads above that expected in actual use, demonstrating safety and design margin. Proof testing is nominally a nondestructive test, particularly if both design margins and test levels are well-chosen. However, unit failures are by definition considered to have been destroyed for their originally-intended use and load levels. Proof tests may be performed before a new design or unit is allowed to enter service, or perform additional uses, or to verify that an existing unit is still functional as intended.Test intervals for in-servic ...

Primer (firearm)
In firearms and artillery, the primer () is the chemical and/or device responsible for initiating the propellant combustion that will push 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. This external powder was connected through a small opening at the rear of the gun barrel that led to the main charge within the barrel. As gunpowder will not burn when wet, this made it difficult (or even impossible) to fire these types of weapons in rainy or humid conditions. Modern primers, by contrast, are more specialized and distinct from the main propellant they are designed to ignite. They are of two types, those using shock-sensitive chemicals, and those rel ...

Rifling
In firearms, rifling is machining helical grooves into the internal (bore) surface of a gun's barrel for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting to stabilize the projectile longitudinally by conservation of angular momentum, improving its aerodynamic stability and accuracy over smoothbore designs. Rifling is characterized by its twist rate, which indicates the distance the rifling takes to complete one full revolution, such as "1 turn in 10 inches" (1:10 inches), "1 turn in 254 mm" ("1:254 mm" or "1:25.4 cm)", or the like. Normally, an experienced shooter can infer the units of measurement from the numbers alone. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will rotate at a higher spin rate. The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it – bar ...
