Combination Guns
A combination gun is a firearm that usually comprises at least one Rifling, rifled barrel and one smoothbore barrel, that is typically used with shot (pellet), shot or some type of shotgun slug. Most have been break-action guns, although there have been other designs as well. Combination guns using one rifled and one smoothbore barrel are commonly found in an over-and-under configuration, while the side-by-side configuration is usually referred to as a cape gun. A combination gun with more than two barrels is called a (German for "triplet") with three barrels, a (German for "quadruplet") with four barrels, and a (German for "quintuplet") with five barrels. Combination guns generally use rimmed cartridges, as rimless cartridges are usually more difficult to extract from a break-action firearm. Use Combination guns have a long history in Europe, the Middle East, Asia, and Africa that date back to the early days of metallic cartridge firearms. These guns are almost exclusively h ...

Combination Gun Examples
In mathematics, a combination is a selection of items from a set (mathematics), set that has distinct members, such that the order of selection does not matter (unlike permutations). For example, given three fruits, say an apple, an orange and a pear, there are three combinations of two that can be drawn from this set: an apple and a pear; an apple and an orange; or a pear and an orange. More formally, a ''k''-combination of a set ''S'' is a subset of ''k'' distinct elements of ''S''. So, two combinations are identical if and only if each combination has the same members. (The arrangement of the members in each set does not matter.) If the set has ''n'' elements, the number of ''k''-combinations, denoted by C(n,k) or C^n_k, is equal to the binomial coefficient \binom nk = \frac, which can be written using factorials as \textstyle\frac whenever k\leq n, and which is zero when k>n. This formula can be derived from the fact that each ''k''-combination of a set ''S'' of ''n'' membe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Sights
Iron sights are a system of physical alignment markers used as a sighting device to assist the accurate aiming of ranged weapons such as firearms, airguns, crossbows, and bows, or less commonly as a primitive finder sight for optical telescopes. Iron sights, which are typically made of metal, are the earliest and simplest type of sighting device. Since iron sights neither magnify nor illuminate the target, they rely completely on the viewer's naked eye and the available light by which the target is visible. In this respect, iron sights are distinctly different from optical sight designs that employ optical manipulation or active illumination, such as telescopic sights, reflector (reflex) sights, holographic sights, and laser sights. Iron sights are typically composed of two components mounted perpendicularly above the weapon's bore axis: a 'rear sight' nearer (or 'proximal') to the shooter's eye, and a 'front sight' farther forward (or 'distal') near the muzzle.

Shotshell
A shotgun cartridge, shotshell, or shell is a type of rimmed, cylindrical (straight-walled) ammunition used specifically in shotguns. It is typically loaded with numerous small, spherical sub-projectiles called shot. Shotguns typically use a smoothbore barrel with a tapered constriction at the muzzle to regulate the extent of scattering. Some cartridges contain a single solid projectile known as a slug (sometimes fired through a rifled slug barrel). The casing usually consists of a paper or plastic tube with a metallic base containing the primer. The shot charge is typically contained by wadding inside the case. The caliber of the cartridge is known as its gauge. The projectiles are traditionally made of lead, but other metals like steel, tungsten and bismuth are also used due to restrictions on lead, or for performance reasons such as achieving higher shot velocities by reducing the mass of the shot charge. Other unusual projectiles such as saboted flechettes, ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trigger (firearms)
A trigger is a mechanism (engineering), mechanism that Actuator, actuates the function of a ranged weapon such as a firearm, airgun, crossbow, or speargun. The word may also be used to describe a switch that initiates the operation of other non-shooting devices such as a animal trap, trap, a power tool, or a quick release. A small amount of energy applied to the trigger leads to the release of much more energy. Most triggers use a small flat or slightly curved lever (called the ''trigger blade'') depressed by the index finger, but some weapons such as the M2 Browning machine gun or the Iron Horse TOR ("thumb-operated receiver") use a push-button-like thumb-actuated trigger design, and others like the Springfield Armory M6 Scout use a squeeze-bar trigger similar to the "ticklers" on crossbow#Medieval Europe, medieval European crossbows. Although the word "trigger" technically implies the entire mechanism (known as the ''trigger group''), colloquially it is usually used to refer ...

303 British
The .303 British (designated as the 303 British by the C.I.P. and SAAMI) or 7.7×56mmR, is a calibre Rim (firearms)#Rimmed, rimmed Tapering (firearms), tapered bottleneck centerfire rifle Cartridge (firearms), cartridge. The .303-inch bore diameter is measured between rifling Rifling, lands as is the common practice in Europe which follows the traditional black powder convention. It was first manufactured in United Kingdom, Britain as a stop-gap black powder round put into service in December 1888 for the Lee–Metford rifle. From 1891 the cartridge used smokeless powder which had been the intention from the outset, but the decision on which smokeless powder to adopt had been delayed. It was the standard British and Commonwealth of Nations, Commonwealth military cartridge for rifles and machine guns from 1889 until it was replaced by the 7.62×51mm NATO in the 1950s. Cartridge specifications The .303 British has a 3.64 litre, mL (56 grain (measure), gr H2O) cartridge case capa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Africa
Southern Africa is the southernmost region of Africa. No definition is agreed upon, but some groupings include the United Nations geoscheme for Africa, United Nations geoscheme, the intergovernmental Southern African Development Community, and the #Definitions and Usage, physical geography definition based on the physical characteristics of the land. The most restrictive definition considers the region of Southern Africa to consist of Botswana, Eswatini, Lesotho, Namibia, and South Africa, while other definitions also include several other countries from the area. Defined by physical geography, Southern Africa is home to several river systems; the Zambezi, Zambezi River is the most prominent. The Zambezi flows from the northwest corner of Zambia and western Angola to the Indian Ocean on the coast of Mozambique. Along the way, it flows over Victoria Falls on the border between Zambia and Zimbabwe. Victoria Falls is one of the largest waterfalls in the world and a major tourist a ...

22 Long Rifle
The .22 long rifle, also known as the .22 LR or 5.7×15mmR, is a long-established variety of .22 caliber rimfire ammunition originating from the United States. It is used in a wide range of firearms including rifles, pistols, revolvers, and submachine guns. In terms of units sold, it is by far the most common ammunition that is manufactured and sold in the world. Common uses include hunting and shooting sports. Ammunition produced in .22 long rifle is effective at short ranges, has little recoil, and is inexpensive to purchase. These qualities make it ideal for plinking and marksmanship training. History American cartridge manufacturer J. Stevens Arms & Tool Company introduced the .22 long rifle cartridge in 1887.The round owes its origin to the .22 BB Cap of 1845 and the .22 Short of 1857. It combined the case of the .22 long of 1871 with a bullet, giving it a longer overall length, a higher muzzle velocity and superior performance as a hunting and target round, render ...

410 Bore
The .410 bore (10.4 mm) is a small caliber shotgun, firing one of the smallest commonly available shotgun shells. A .410 bore shotgun loaded with shot shells is well suited for small game hunting and pest control. The .410 started off in the United Kingdom as a garden gun along with the .360 and the No. 3 bore (9 mm) rimfire, No. 2 bore (7 mm) rimfire, and No. 1 bore (6 mm) rimfire. .410 shells have similar base dimensions to the .45 Colt cartridge, allowing many single-shot firearms, as well as derringers and revolvers chambered in that caliber, to fire .410 shot shells without any modifications. Other small bore shotgun loads include the 9mm Flobert rimfire cartridge, and the less prevalent .22 rimfire shot shell. Origin Lancaster's pattern centerfire and pinfire .410 shot cartridges first appeared in Eley Brothers Ltd. flysheets in 1857. By 1874, Eley was advertising modern centerfire .410 cartridges. It appears to have become popular around 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
22 Hornet
The .22 Hornet or 5.6×36mmR Hornet is a varminting, game (hunting), small-game hunting, survival skills, survival and competition centerfire rifle cartridge commercially introduced in 1930. It is considerably more powerful than either the .22 WMR and the .17 HMR rimfire ammunition, rimfire cartridges, achieving a higher velocity with a bullet twice the weight of that used in the .17 HMR. The Hornet also differs significantly from these in that being a centerfire cartridge makes it Handloading, reloadable, and thus more versatile. It was also the smallest commercially available .22 caliber centerfire cartridge until the introduction of the FN 5.7×28mm. The .22 Hornet should not be confused with the 5.6x35mmR Vierling. As per C.I.P., the Hornet case has a longer shoulder length, case length and thicker rim than the Vierling. This makes it very difficult to chamber the higher pressure Hornet cartridge in a Vierling rifle. The .22 Hornet fills the gap between such popular Varm ...
