Armor-piercing Bullet
Armor-piercing bullets for rifle and handgun cartridges are designed to penetrate ballistic armor and protective shields intended to stop or deflect conventional bullets. Although bullet design is an important factor with regard to armor penetration, the ability of any given projectile to penetrate ballistic armor increases with increasing velocity. Rifle cartridges typically discharge bullets at higher muzzle velocity than handgun cartridges due to larger propellant charge. However, even the same cartridge (one that is interchangeable between specific rifles and handguns) fired from a rifle will, in almost all common cases, have a higher velocity than when fired from a handgun. This is due to the longer period of acceleration available within the longer gun barrel of rifles, which allow adequate time for the propellant to fully ignite before the projectile exits the barrel. For this reason, bullets fired from rifles may be more capable of piercing armor than similar or id ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cupronickel
Cupronickel or copper-nickel (CuNi) is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. The copper content typically varies from 60 to 90 percent. (Monel is a nickel-copper alloy that contains a minimum of 52 percent nickel.) Despite its high copper content, cupronickel is silver in colour. Cupronickel is highly resistant to corrosion by salt water, and is therefore used for piping, heat exchangers and condensers in seawater systems, as well as for marine hardware. It is sometimes used for the propellers, propeller shafts, and hulls of high-quality boats. Other uses include military equipment and chemical, petrochemical, and electrical industries. Another common 20th-century use of cupronickel was silver-coloured coins. For this use, the typical alloy has 3:1 copper to nickel ratio, with very small amounts of manganese. In the past, true silver coins were debased with cupronickel, such as coins of the pound sterling from 1947 onwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ricochet
A ricochet ( ; ) is a rebound, bounce, or skip off a surface, particularly in the case of a projectile. Most ricochets are caused by accident and while the force of the deflection decelerates the projectile, it can still be energetic and almost as dangerous as before the deflection. The possibility of ricochet is one of the reasons for the common firearms safety rule "Never shoot at a flat, hard surface." Ricochets can occur with ''any'' caliber, but short or round ricocheting bullets may not produce the audible whine caused by tumbling irregular shapes. Ricochets are a hazard of shooting because, for as long as they retain sufficient velocity, ricocheting bullets or bullet fragments may cause collateral damage to animals, objects, or even the person who fired the shot. Variables Ricochets occur when a bullet or bullet fragment is deflected by an object rather than penetrating and becoming embedded in that object. Ricochet behavior may vary with bullet shape, bullet material, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teflon-coated Bullet
Teflon-coated bullets, sometimes colloquially, also known as "cop killer bullets", are bullets that have been covered with a coating of polytetrafluoroethylene. History In the 1960s, Paul Kopsch (an Ohio coroner), Daniel Turcus (a police sergeant), and Donald Ward (Kopsch's special investigator) began experimenting with special purpose handgun ammunition. Their objective was to develop a law enforcement round capable of improved penetration against hard targets, such as windshield glass and automobile doors. Conventional bullets, made primarily from lead, often become deformed and less effective after striking hard targets, especially when fired at handgun velocities. The inventors named their company "KTW," after their initials. After some experimentation with sintered tungsten-alloy Kennertium W-10 projectiles, which were eventually abandoned due to supply and cost concerns, the inventors settled on a bullet consisting mostly of hard brass and some with a steel projectile.

Brass
Brass is an alloy of copper (Cu) and zinc (Zn), in proportions which can be varied to achieve different mechanical, electrical, and chemical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, another copper alloy, that uses tin instead of zinc. Both bronze and brass may include small proportions of a range of other elements including arsenic (As), lead (Pb), phosphorus (P), aluminium (Al), manganese (Mn), and silicon (Si). Historically, the distinction between the two alloys has been less consistent and clear, and modern practice in museums and archaeology increasingly avoids both terms for historical objects in favor of the more general "copper alloy". Brass has long been a popular material for decoration due to its bright, gold-like appearance; being used for drawer pulls and doorknobs. It has also been widely used to make utensils because of its low melti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Western Cartridge Company
The Western Cartridge Company is an American manufacturer of small arms and ammunition that is based in East Alton, Illinois. Founded in 1898, it was the forerunner of the Olin Corporation, formed in 1944, of which Western is still a subsidiary. Western acquired the Winchester Repeating Arms Company after Winchester went into receivership in 1931. History Franklin W. Olin received an engineering degree from Cornell University in 1886. After working at powder mills in the eastern United States, he was one of several investors establishing the Equitable Powder Company in 1892 at East Alton, Illinois. Production of blasting powder for southern Illinois coal mining began in 1893. Olin formed the Western Cartridge Company in 1898 to manufacture sporting rifle powder and shotgun shells for settlers of the Great Plains. The shotgun shells used primers manufactured by larger eastern ammunition firms. When the firms with primer manufacturing facilities raised primer prices in 1900 to ...

50 BMG
The .50 Browning Machine Gun (.50 BMG, 12.7×99mm NATO and designated as the 50 Browning by the C.I.P.) is a caliber cartridge developed for the M2 Browning heavy machine gun in the late 1910s, entering official service in 1921. Under STANAG 4383, it is a standard service cartridge for NATO forces as well as many non-NATO countries. The cartridge itself has been made in many variants: multiple generations of regular ball, tracer, armor-piercing (AP), incendiary, and saboted sub-caliber rounds. The rounds intended for machine guns are made into a continuous belt using metallic links. The .50 BMG cartridge is also used in anti-materiel rifles. A wide variety of ammunition is available, and the availability of match grade ammunition has increased the usefulness of .50 caliber rifles by allowing more accurate fire than lower quality rounds. History In response to the need for new anti-aircraft weaponry during World War I, John Browning developed the .50 BMG. He wanted the ...

Raufoss Mk 211
The Raufoss Mk 211 is a .50 BMG (12.7×99mm NATO) multi-purpose anti-materiel high-explosive incendiary/armor-piercing ammunition projectile produced by Nammo under the model name ''NM140 MP''. It is commonly referred to as ''multipurpose'' or ''Raufoss'', meaning '' red waterfall'' in Norwegian. This refers to Nammo's precursor company Raufoss Ammunisjonsfabrikker, an ammunition manufacturer established 1896 in Raufoss, Norway. The "Mk 211" name comes from the nomenclature ''Mk 211 Mod 0'' used by the U.S. military for this round. Design details The multipurpose concept developed by Raufoss is unique in that, instead of using a mechanical fuse, it uses a pyrotechnical ignition train to ensure proper deflagration (not detonation) of the explosive and incendiary components. The multipurpose name is based on an armor-piercing tungsten core, a slow explosive, and an incendiary component, thus making it capable of penetrating lightly armored targets and causing damage to person ...

338 Lapua Magnum
The .338 Lapua Magnum (8.6×70 mm or 8.58×70 mm) is a rimless, bottlenecked, centerfire rifle cartridge. It was developed during the 1980s as a high-powered, long-range cartridge for military snipers. It was used in the War in Afghanistan and the Iraq War. As a result of this, it has become widely available. The loaded .338 cartridge is in diameter (rim) and long. It can penetrate better-than-standard military body armor at ranges of up to , and has a maximum effective range of about with C.I.P. conforming ammunition at sea level conditions. Muzzle velocity is dependent on barrel length, seating depth, and powder charge, and varies from for commercial loads with bullets, which corresponds to about of muzzle energy.

K Bullet
The K bullet (from German 'Kern', core) was a 7.92×57mm Mauser armor-piercing bullet with a tool steel core designed to be fired from a standard Mauser rifle. History The German Army first employed a " reversed bullet" with a heavier powder charge behind it as an early anti-tank method against the British heavy tanks of World War I. This did prove effective against the thinner-armored Mark I tank models, mainly by causing spalling from the inside surface of the armor hit. Reversed bullet loads were however unsafe to use in the standard issue Mauser rifle and thus were unpopular with German troops. They became obsolete with the introduction of more heavily armored tanks. As a replacement, the Germans conceived the "K bullet", which was purposely developed as an armor-piercing ammunition. The K bullet was in use by the battle of Messines Ridge in June 1917 and had one out of three chance to penetrate 12–13 mm thick armor at a range of up to 100 meters. With the Briti ...
