9.3×64mm Brenneke
The 9.3×64mm Brenneke (designated as the 9,3 x 64 Brenneke by the C.I.P.) is a rimless bottlenecked centerfire rifle cartridge designed in 1927 by German gunmaker Wilhelm Brenneke. It is suitable for hunting medium to large game animals in Africa, Asia, Europe, and North America. The 9.3×64mm Brenneke was designed as a medium bore big-game cartridge for standard-sized Mauser 98 bolt-action rifles. History One of the most successful cartridge designs of the famous German gun and ammunition designer Wilhelm Brenneke was the 9.3×64mm Brenneke. He designed this cartridge ''ex novo'' (the 9.3×64mm Brenneke has no other cartridge as a parent case) and introduced it commercially in 1927. This big-game cartridge is the most powerful cartridge he designed. The 9.3×64mm Brenneke was designed to have the largest possible case capacity without any shape or dimensional drawbacks that would hamper its chambering and perfect functioning in Mauser Gewehr 98 rifles that were then stand ...

Cartridge (firearms)
A cartridge, also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile ( bullet, shot, or slug), a propellant substance ( smokeless powder, black powder substitute, 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 convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often used to refer to a complete cartridge, the correct usage only refers to the projectile. Military and commercial producers continue to pursue the goal of caseless ammunition. Some artillery ammunition uses the same cartridge concept as found in small arms. In other cases, the artillery shell is separate from the propellant charge. A cartridge without a projectile is called a '' blank''; one that is completely inert (contains no active primer and no propellant) is called a '' dummy''; one that ...

SVDK
SVDK (, GRAU index 6V9), the "''Dragunov sniper rifle, large-calibre''" (Снайперская винтовка Драгунова крупнокалиберная), is a Russian precision rifle from the SVD rifle family chambered for the 9.3×64mm Brenneke, 9.3×64mm 7N33 cartridge.Юрий Пономарёв. СВДК — «младшая сестра» СВД // журнал «Калашников. Оружие. Боеприпасы. Снаряжение», № 7, 2007. стр.42-46 Description The Dragunov SVDK large-caliber sniper rifle (any rifle caliber above 9 mm is considered a large caliber in Russia) is a somewhat controversial weapon. It was developed through "burglar" (Breaker) research and development program, along with 7.62 mm SV-98 sniper and 12.7 mm KSVK 12.7, ASVK anti-materiel rifles. The purpose of SVDK is to deal with targets which are too hard for standard 7.62×54mmR sniper rifles like SV-98 or SVD rifle, SVD, such as assault troops in h ...

Minute Of Arc
A minute of arc, arcminute (abbreviated as arcmin), arc minute, or minute arc, denoted by the symbol , is a unit of angular measurement equal to of a degree. Since one degree is of a turn, or complete rotation, one arcminute is of a turn. The nautical mile (nmi) was originally defined as the arc length of a minute of latitude on a spherical Earth, so the actual Earth's circumference is very near . A minute of arc is of a radian. A second of arc, arcsecond (abbreviated as arcsec), or arc second, denoted by the symbol , is a unit of angular measurement equal to of a minute of arc, of a degree, of a turn, and (about ) of a radian. These units originated in Babylonian astronomy as sexagesimal (base 60) subdivisions of the degree; they are used in fields that involve very small angles, such as astronomy, optometry, ophthalmology, optics, navigation, land surveying, and marksmanship. To express even smaller angles, standard SI prefixes can be employed; the milliar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plains Game
Plains game is well established in literature and conversation as the sporting hunter's generic term for all those fair-game species of antelope and gazelle which are to be found - typically in rather open plains or savanna habitats - throughout sub-Saharan Africa. The term is all-embracing, unscientific, and rather imprecise. Impala and Thomson's gazelle are classic examples of plains game, but the term also encompasses a great range of species from the diminutive steenbok to the massive eland. Plains game species are distinct from species of dangerous game, which generally consists of the Big 5 as well as crocodile and hippopotamus. For this reason, virtually any species of game in Africa that is not considered dangerous game may be broadly referred to as plains game. Where the term "plains game" is used as an indication of the kind of game for which particular sporting rifle cartridges are deemed suitable, it is fair to assume that the same ammunition also performs efficie ...

Big-game Hunting
Big-game hunting is the hunting of large game animals for trophies, taxidermy, meat, and commercially valuable animal by-products (such as horns, antlers, tusks, bones, fur, body fat, or special organs). The term is often associated with the hunting of Africa's "Big Five" game (lion, African elephant, Cape buffalo, African leopard, and African rhinoceros), and Indian rhinoceros and Bengal tigers on the Indian subcontinent. History Hunting of big game for food is an ancient practice, possibly arising with the emergence of ''Homo sapiens'' ( anatomically modern humans), and possibly pre-dating it, given the known propensity of other great apes to hunt, and even eat their own species. The Schöningen spears and their correlation of finds are evidence that complex technological skills already existed 300,000 years ago, and are the first obvious proof of an active big game hunt. ''H. heidelbergensis'' already had intellectual and cognitive skills like anticipatory plannin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muzzle Brake
A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. Barrels with an integral muzzle brake are often said to be ported. The concept of a muzzle brake was first introduced for artillery. It was a common feature on many anti-tank guns, especially those mounted on tanks, in order to reduce the area needed to take up the strokes of recoil and kickback. They have been used in various forms for rifles and pistols to help control recoil and the rising of the barrel that normally occurs after firing. They are used on pistols for practical pistol competitions, and are usually called compensators in this context.STI article o ...

Proof (firearms)
A proof test is a form of stress test to demonstrate the fitness of a load-bearing or impact-experiencing 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 those 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.Tes ...

Percussion Cap
The percussion cap, percussion primer, or caplock, introduced in the early 1820s, is a type of single-use percussion ignition device for muzzle loader firearm locks enabling them to fire reliably in any weather condition. Its invention gave rise to the caplock mechanism or percussion lock system which used percussion caps struck by the hammer to set off the gunpowder charge in rifles and cap and ball firearms. Any firearm using a caplock mechanism is a percussion gun. Any long gun with a cap-lock mechanism and rifled barrel is a percussion rifle. Cap and ball describes cap-lock firearms discharging a single bore-diameter spherical bullet with each shot. Description The percussion cap is a small cylinder of copper or brass with one closed end. Inside the closed end is a small amount of a shock-sensitive explosive material such as mercury fulminate (discovered in 1800; it was the only practical detonator used from about the mid-19th century to the early 20th century). ...

Twist Rate
Rifling is the term for helical grooves machined into the internal surface of a firearms's barrel for imparting a spin to a projectile to improve its aerodynamic stability and accuracy. It is also the term (as a verb) for creating such grooves. The opposite of rifling is smoothbore. Rifling is measured in ''twist rate'', the distance the rifling takes to complete one full revolution, expressed as a ratio with 1 as its base (e.g., 1:). A shorter distance/lower ratio indicates a faster twist, generating a higher spin rate (and greater projectile stability). The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it: barrels intended for short, large-diameter projectiles such as spherical lead balls require a very low twist rate, such as 1 turn in 48 inches (122 cm). Barrels intended for long, small-diameter projectiles, such as the ultra-low-drag 80-grain 0.223 inch bullets (5.2 g, 5.56&nbs ...
