Foster Slug
A shotgun slug is a heavy projectile made of lead, copper, or other material and fired from a shotgun. Slugs are designed for hunting large game, and other uses, particularly in areas near human population where their short range and slow speed helps increase safety margin. The first effective modern shotgun slug was introduced by Wilhelm Brenneke in 1898, and his design remains in use today. Most shotgun slugs are designed to be fired through a cylinder bore, improved cylinder choke, rifled choke tubes, or fully rifled bores. Slugs differ from round shot, round ball lead projectiles in that they are stabilized in some manner. In the early development of firearms, smooth-bored barrels were not differentiated to fire either single or multiple projectiles. Single projectiles were used for larger game and warfare, though shot could be loaded as needed for small game, birds, and activities such as trench clearing. As firearms became specialized and differentiated, shotguns were still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brenneke Slug-1
Brenneke GmbH is a German manufacturer of ammunition and bullets, based in Langenhagen, Lower Saxony. The company was founded by Wilhelm Brenneke in 1895 and is currently owned and run by his great-grandson, Dr. Peter Mank. Brenneke makes shotgun shells for target shooting and hunting, special slugs for law enforcement, and hunting rounds as well as projectiles for handloading. Its best-known products are the Brenneke slug for shotguns and a line of rifle bullets. Langenhagen standard In 1990 under the sponsorship of Brenneke, the Langenhagen standard (german: Langenhagener Norm) was created. Essentially it means that for hunting, the deviation of the shotgun slug must not on a distance of exceed a circle with diameter. On a drilling, the total deviation of all three barrels must not exceed a circle of diameter. Rifle bullets All Brenneke rifle bullets have a so-called ''torpedo-tail'' (german: Torpedo-Heck), a special form of boat-tail. The best-known are * TIG ...

Shotgun
A shotgun (also known as a scattergun, or historically as a fowling piece) is a long gun, long-barreled firearm designed to shoot a straight-walled cartridge (firearms), cartridge known as a shotshell, which usually discharges numerous small pellets (petrology), pellet-like spherical sub-projectiles called shot (pellet), shot, or sometimes a single solid projectile called a shotgun slug, slug. Shotguns are most commonly smoothbore firearms, meaning that their gun barrels have no rifling on the inner wall, but rifled barrels for shooting slugs (slug barrels) are also available. Shotguns come in a wide variety of calibers and Gauge (firearms), gauges ranging from 5.5 mm (.22 inch) to up to , though the 12-gauge (18.53 mm or 0.729 in) and 20-gauge (15.63 mm or 0.615 in) bores are by far the most common. Almost all are breechloading, and can be single-barreled, double barreled shotgun, double-barreled, or in the form of a combination gun. Like rifles, ...

7mm Remington Magnum
The 7mm Remington Magnum rifle cartridge was introduced as a commercially available round in 1962, along with the new Remington Model 700 bolt-action rifle. It is a member of the belted magnum family that is directly derived from the venerable .375 H&H Magnum.Speer Reloading Manual The original purpose of the belted magnum concept taken from the .300 H&H Magnum and .375 H&H Magnum, was to provide precise headspace control, since the sloping shoulders, while easing cartridge extraction, were unsuitable for this purpose. Improved cartridge extraction reliability is desirable while hunting dangerous game, in particular when a fast follow-up shot is required. The 7mm Remington Magnum is based on the commercial .264 Winchester Magnum, .338 Winchester Magnum, and .458 Winchester Magnum, which were based on the same belted .300 H&H Magnum and .375 H&H Magnum cases, trimmed to nearly the same length as the .270 Weatherby Magnum.

Feet Per Second
The foot per second (plural feet per second) is a unit of both speed (scalar) and velocity (vector quantity, which includes direction). It expresses the distance in feet (ft) traveled or displaced, divided by the time in seconds (s). The corresponding unit in the International System of Units (SI) is the meter per second. Abbreviations include ft/s, fps, and the scientific notation ft sā1. Conversions See also *Foot per second squared, a corresponding unit of acceleration. *Feet per minute The foot (plural, : feet) is an anatomical structure found in many vertebrates. It is the terminal portion of a limb (anatomy), limb which bears weight and allows animal locomotion, locomotion. In many animals with feet, the foot is a separate o ...

Grain (unit)
A grain is a unit of measurement of mass, and in the troy weight, avoirdupois, and apothecaries' systems, equal to exactly milligrams. It is nominally based upon the mass of a single ideal seed of a cereal. From the Bronze Age into the Renaissance, the average masses of wheat and barley grains were part of the legal definitions of units of mass. Expressions such as "thirty-two grains of wheat, taken from the middle of the ear" appear to have been ritualistic formulas, essentially the premodern equivalent of legal boilerplate. Another source states that it was defined such that 252.458 units would balance of distilled water at an ambient air-water pressure and temperature of and respectively. Another book states that Captain Henry Kater, of the British Standards Commission, arrived at this value experimentally. The grain was the legal foundation of traditional English weight systems, and is the only unit that is equal throughout the troy, avoirdupois, and apothecaries' sys ...

Stopping Power
Stopping power is the ability of a weapon ā typically a ranged weapon such as a firearm ā to cause a target (human or animal) to be incapacitated or immobilized. Stopping power contrasts with lethality in that it pertains only to a weapon's ability to make the target cease action, regardless of whether or not death ultimately occurs. Which ammunition cartridges have the greatest stopping power is a much debated topic. Stopping power is related to the physical properties and terminal behavior of the projectile (bullet, shot, or slug), the biology of the target, and the wound location, but the issue is complicated and not easily studied. Although higher-caliber ammunitions usually have greater muzzle energy and momentum and thus traditionally been widely associated with higher stopping power, the physics involved are multifactorial, with caliber, muzzle velocity, bullet mass, bullet shape and bullet material all contributing to the ballistics. Despite much disagreement, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taylor Knock-out Factor
The Taylor knock-out factor, also called Taylor KO factor or TKOF, is a formulaic mathematical approach for evaluating the stopping power of hunting cartridges, developed by John "Pondoro" Taylor in the middle of the 20th century. Taylor, an elephant hunter and author who wrote two books about rifles and cartridges for African hunting, devised the formula as a means of comparing the ability of a cartridge to deliver a knock out blow to elephant from a shot to the head when the brain is missed. Formula The Taylor KO factor multiplies bullet mass (measured in grains) by muzzle velocity (measured in feet per second) by bullet diameter (measured in inches) and then divides the product by 7,000, converting the value from grains to pounds and giving a numerical value from 0 to ~150 for normal hunting cartridges. It is proportional to the momentum at the muzzle times the diameter of the bullet. Expressed as a fraction, the Taylor KO Factor is: :\mathrm=\frac Example calculation Using th ...

Gauge (bore Diameter)
The gauge (or commonly bore in British English) of a firearm is a unit of measurement used to express the inner diameter (bore diameter) of the barrel. Gauge is determined from the weight of a solid sphere of lead that will fit the bore of the firearm and is expressed as the multiplicative inverse of the sphere's weight as a fraction of a pound, e.g., a one-twelfth pound lead ball fits a 12-gauge bore. Thus there are twelve 12-gauge balls per pound, etc. The term is related to the measurement of cannon, which were also measured by the weight of their iron round shot; an 8-pounder would fire an 8 lb (3.6 kg) ball. Gauge is commonly used today in reference to shotguns, though historically it was also used in large double rifles, which were made in sizes up to 2 bore during their heyday in the 1880s, being originally loaded with black powder cartridges. These very large rifles, called "elephant guns", were intended for use primarily in Africa and Asia for hunting lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SAAMI
The Sporting Arms and Ammunition Manufacturers' Institute (SAAMI, pronounced "Sammy") is an association of American manufacturers of firearms, ammunition, and components. SAAMI is an accredited standards developer that publishes several American National Standards that provide safety, reliability, and interchangeability standards for commercial manufacturers of firearms, ammunition, and components. In addition, SAAMI publishes information on the safe and responsible transportation, storage, and use of those products. History The origins of SAAMI date back to World War I and the Society of American Manufacturers of Small Arms and Ammunition (SAMSAA). In 1913, the US War Department encouraged the firearms and ammunition industry to establish an organization to share new technology and establish common standards for small arms and ammunition. SAMSAA was officially formed in 1918, however became inactive by the early 1920s. By the mid-1920s the United States was still suffering ...

Riot Shotgun
A riot shotgun is a shotgun designed or modified for use as a primarily defensive weapon, by the use of a short barrel and sometimes a larger magazine capacity than shotguns marketed for hunting. The riot shotgun is used by military personnel for guard duty and was at one time used for riot control, and is commonly used as a door breaching and patrol weapon by law enforcement personnel, as well as a home defense weapon by civilians. Guns of this type are often labeled as breaching shotguns, tactical shotguns or special-purpose shotguns to denote the larger scope of their use; however, these are largely marketing terms. Characteristics The primary characteristic of a riot shotgun is a "short" barrel (generally 14 to 20" long; 18" is the shortest length available to civilians in the U.S. that is not subject to additional federal ATF regulation) which makes the shotgun more compact and easier to handle, easier to stow inside a police vehicle, and more suitable for quick aiming at ( ...

Bean Bag Round
A bean bag round, also known by its trademarked name flexible baton round, is a type of baton round, fired from a shotgun, and used for less lethal apprehension of suspects. Description The bean bag round consists of a small fabric "pillow" filled with #9 lead shot weighing about . It is fired from a normal 12-gauge shotgun. When fired, the bag is expelled at around ; it spreads out in flight and distributes its impact over about of the target. It is designed to deliver a blow that will cause minimum long-term trauma and no penetration but will result in a muscle spasm or other reaction to briefly render a violent suspect immobile. It still can cause serious injury and death. The shotgun round is inaccurate over about and has a maximum range of around . Changes to the bean bag round since its inception in the early 1970s have included a velocity reduction from 120 to 90 meters per second (400 to 300 ft/s) as well as a shift from a square shape to a more rounded sock-shap ...

Guide
A guide is a person who leads travelers, sportspeople, or tourists through unknown or unfamiliar locations. The term can also be applied to a person who leads others to more abstract goals such as knowledge or wisdom. Travel and recreation Explorers in the past venturing into territory unknown by their own people invariably hired guides. Military explorers Lewis and Clark were hired by the United States Congress to explore the Pacific Northwest. They in turn hired the better qualified Native American Sacagawea to help them. Wilfred Thesiger hired guides in the deserts that he ventured into, such as Kuri on his journey to the Tibesti Mountains in 1938. Tour guide Tour guides lead visitors through tourist attractions and give information about the attractions' natural and cultural significance. Often, they also act as interpreters for travelers who do not speak the local language. Automated systems like audio tours are sometimes substituted for human tour guides. Tour operators ...
