.416 Taylor
The .416 Taylor is a rifle cartridge. According to Ken Waters in ''Pet Loads'', it was created by Robert Chatfield-Taylor in the early 1970s, with the first rifle in this caliber being a factory barreled Winchester Model 70. The case is based on the .458 Winchester Magnum necked down to accept .416 caliber bullets. Usage The .416 Taylor uses a bullet diameter. With maximum loads, the cartridge is capable of propelling a bullet at an average of from a barrel yielding a muzzle energy of . The work on this caliber (performed by Waters) was done with an experimental factory Ruger Model 77. He reported that an absolute maximum load of certain listed powders would push a bullet to , thereby equaling (and perhaps exceeding) the performance of the .416 Rigby (presuming moderate temperatures and barometric pressures). Waters also reported that bullets could exceed when propelled by certain listed powders. Under normal hunting conditions, the Taylor cartridge is therefore capable ...

458 Winchester Magnum
The .458 Winchester Magnum is a belted, straight-taper cased, big five game rifle cartridge. It was introduced commercially in 1956 by Winchester and first chambered in the Winchester Model 70 African rifle. It was designed to compete against the .450 Nitro Express and the .470 Nitro Express cartridges used in big bore British double rifles. The .458 Winchester Magnum remains one of the most popular large game cartridges, and most major ammunition manufacturers offer a selection of .458 ammunition. History The .458 Winchester Magnum was designed for hunting dangerous game animals by emulating the performance of powerful English double rifle cartridges in a bolt-action rifle. The use of a bolt-action rifle offered hunters a cheaper alternative to the big-bore double rifle, and ammunition could be manufactured using available tooling. The .458 Winchester Magnum soon became a success as dangerous game hunters adopted the cartridge. Soon game wardens, wildlife managers, and profes ...

Winchester Model 70
The Winchester Model 70 is a bolt-action sporting rifle. It has an iconic place in American sporting culture and has been held in high regard by shooters since it was introduced in 1936, earning the moniker "The Rifleman's Rifle". The action has some design similarities to Mauser designs and it is a development of the earlier Winchester Model 54, itself based on a Mauser 98-type action. The Model 70 was originally manufactured by the Winchester Repeating Arms Company between 1936 and 1980. From the early 1980s until 2006, Winchester rifles were manufactured by U.S. Repeating Arms under an agreement with Olin Corporation, allowing USRA to use the Winchester name and logo. Model 70s were built in New Haven, Connecticut, from 1936 to 2006, when production ceased. In the fall of 2007, the Belgian company FN Herstal announced that Model 70 production would resume. As of 2012, new Winchester Model 70 rifles were being made by FN Herstal in Columbia, South Carolina. In 2013, assembly wa ...

Ruger Model 77
The Ruger M77 is a bolt-action rifle produced by Sturm, Ruger & Company. It was designed by Jim Sullivan during his three years with Ruger. The rifle features a traditional Mauser-style two-lugged bolt with a claw extractor. Design and features From the beginning, the Ruger M77 was intended as a modernized Mauser 98, though numerous changes were made. Bill Ruger wanted to use investment casting in place of a forged receiver. The Sullivan-designed bolt dispensed with the Mauser blade type ejector and instead used the simpler plunger style of ejector. A two-position tang safety and redesigned trigger system were also designed from scratch. Perhaps the most novel feature of the M77 is the only one that has not been redesigned, the angled action screw. The front action screw of traditional bolt-action rifles draws the receiver directly down against the stock. The M77 uses an angled screw that draws the action down and to the rear, tightly bedding it against the stock. Variants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Browning BAR
The Browning BAR is a gas-operated, semi-automatic rifle produced by the Browning Arms Company in Belgium. The rifle loads from a detachable box magazine. Browning introduced a redesigned BAR in 1966. Variants There are several models of the Browning BAR; Safari, Long- and ShortTrac, and Lightweight Stalker. Both LongTrac and ShortTrac versions are available in a Mossy Oak takedown, basic, and Stalker variant. The Safari model has an engraved steel receiver and walnut stock. The barrel is long, depending on the cartridge. The Safari is the only model with the Browning BOSS (Ballistic Optimizing Shooting System). The system reduces recoil and enhances accuracy with an adjustable muzzle brake and weight. The Lightweight Stalker model has an aluminum-alloy receiver. The stock is matte black synthetic instead of a walnut stock. The stalker is the only model to feature iron sights. The barrel is long. LongTrac and ShortTrac models feature an aluminum-alloy receiver, a plastic t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 gun is di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
External Ballistics
External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying through an atmosphere or in the vacuum of space, but most certainly flying under the influence of a gravitational field. Gun-launched projectiles may be unpowered, deriving all their velocity from the propellant's ignition until the projectile exits the gun barrel. However, exterior ballistics analysis also deals with the trajectories of rocket-assisted gun-launched projectiles and gun-launched rockets; and rockets that acquire all their trajectory velocity from the interior ballistics of their on-board propulsion system, either a rocket motor or air-breathing engine, both during their boost phase and after motor burnout. External ballistics is also concerned with the free-flight of other projectiles, such as balls, arrows etc. Forces acting on the projectile W ...
