28-gauge
The gauge (in American English or more commonly referred to as bore in British English) of a firearm is a unit of measurement used to express the inner diameter (bore diameter) and other necessary parameters to define in general a smoothbore barrel (compare to caliber, which defines a barrel with rifling and its cartridge). The gauge of a shotgun is a list that includes all necessary data to define a functional barrel. For example, the dimension of the chamber, the shotgun bore dimension and the valid proof load and commercial ammunition, as defined globally by the C.I.P.; defined in Great Britain by the ''Rules, regulations and scales applicable to the proof of small arms'' (2006) of The London Proof House and The Birmingham Proof House, as referred in the Gun Barrel Proof Act 1978, Paragraph 6; and defined in the United States by SAAMI Z299.2 – 2019. Historical development The concept of using a material property to define a bore diameter was used before the term gauge, ...

Shotgun
A shotgun (also known as a scattergun, peppergun, 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 discharges numerous small spherical projectiles called shot (pellet), shot, or a single solid projectile called a shotgun slug, slug. Shotguns are most commonly used as smoothbore firearms, meaning that their gun barrels have no rifling on the inner wall, but rifled barrels for shooting Sabot (firearms), sabot 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, shotguns also ...

45 ACP
The .45 ACP (Automatic Colt Pistol), also known as .45 Auto, .45 Automatic, or 11.43×23mm is a Rim (firearms)#Rimless, rimless straight-walled handgun Cartridge (firearms), cartridge designed by John Moses Browning in 1904, for use in his prototype Colt's Manufacturing Company, Colt semi-automatic pistol. After successful military trials, it was adopted as the standard chambering for Colt's M1911 pistol. The round was developed due to a lack of stopping power experienced in the Moro Rebellion in places like Sulu. The issued ammunition, .38 Long Colt, had proved inadequate, motivating the search for a better cartridge. This experience and the Thompson–LaGarde Tests of 1904 led the Army and the Cavalry to decide that a minimum of .45 caliber was required in a new handgun cartridge. The standard-issue military .45 ACP cartridge uses a round-nose bullet at approximately fired from a government-issue M1911A1 pistol. It operates at a relatively low maximum chamber pressure rating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Round Shot
A round shot (also called solid shot or simply ball) is a solid spherical projectile without explosive charge, launched from a gun. Its diameter is slightly less than the bore of the barrel from which it is shot. A round shot fired from a large-caliber gun is also called a cannonball. The cast iron cannonball was introduced by French artillery engineers after 1450; it had the capacity to reduce traditional English castle wall fortifications to rubble. French armories would cast a tubular cannon body in a single piece, and cannonballs took the shape of a sphere initially made from stone material. Advances in gunpowder manufacturing soon led the replacement of stone cannonballs with cast iron ones. Round shot was made in early times from dressed stone, referred to as gunstone (Middle English: ''gunneston''), but by the 17th century, from iron. It was used as the most accurate projectile that could be fired by a smoothbore cannon, used to batter the wooden hulls of oppos ...

Inch
The inch (symbol: in or prime (symbol), ) is a Units of measurement, unit of length in the imperial units, British Imperial and the United States customary units, United States customary System of measurement, systems of measurement. It is equal to yard or of a foot (unit), foot. Derived from the Uncia (unit), Roman uncia ("twelfth"), the word ''inch'' is also sometimes used to translate similar units in other measurement systems, anthropic units, usually understood as deriving from the width of the human thumb. Standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s the inch has been based on the metric system and defined as exactly 25.4Millimetre, mm. Name The English word "inch" () was an early borrowing from Latin ' ("one-twelfth; Roman inch; Roman ounce"). The vowel change from Latin to Old English (which became Modern English ) is known as Germanic umlaut, umlaut. The consonant c ...

Fraction
A fraction (from , "broken") represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. A ''common'', ''vulgar'', or ''simple'' fraction (examples: and ) consists of an integer numerator, displayed above a line (or before a slash like ), and a division by zero, non-zero integer denominator, displayed below (or after) that line. If these integers are positive, then the numerator represents a number of equal parts, and the denominator indicates how many of those parts make up a unit or a whole. For example, in the fraction , the numerator 3 indicates that the fraction represents 3 equal parts, and the denominator 4 indicates that 4 parts make up a whole. The picture to the right illustrates of a cake. Fractions can be used to represent ratios and division (mathematics), division. Thus the fraction can be used to ...

Elephant Gun
An elephant gun is a large caliber gun, rifled or smoothbore, originally developed for use by big-game hunters for elephant and other large game. Elephant guns were black powder muzzle-loaders at first, then black powder express rifles, then later used smokeless powder cartridges. Early use As Europeans made inroads into Africa in the early 19th century, guns were developed to handle the very large game encountered. This was for self-protection, food gathering, and sport. The first guns were the simple muzzle-loading shotgun designs already used for birds and loaded with solid balls of lead for use on large game. Due to their ineffectiveness on the largest game (up to 35 shots being recorded by some writers for a single elephant), they soon developed into larger caliber black powder smoothbores. The caliber was still measured in bore or gauge—10, 8, 6, 4 bore, and 2 bore—or the guns were named by number of projectiles per pound. The projectiles were lead round ball ...

2 Bore
Two bore or 2 bore is an obsolete firearm caliber. Specifications Two bore firearms generally fire spherical balls or slugs made of hardened lead, or in the case of a modern metallic cartridge with either solid brass or bronze projectiles. The nominal bore is , and projectiles generally weigh 8 ounces (227 grams; 3500 grains). The velocity is relatively low, at around at the muzzle, but develops approximately muzzle energy. History and background Despite the popularity of the calibre in modern gun lore there is no evidence the 2 bore as named was actually used as a terrestrial and shoulder fired firearm. The equivalent calibre size equates to various punt guns used for harvesting large number of waterfowls usually mounted in 'punts' or flat bottomed boats for commercial purposes. A common misconception is the hunter Sir Samuel White Baker being attributed to its use, however his firearm 'Baby' as described below was actually close to 3 bore, the firearms records still ex ...

Double Rifle
The double rifle, also known as a double-barreled rifle, is a rifle with two barrels mounted parallel to each other that can be fired simultaneously or sequentially in quick succession. Synonymous with big game hunting found primarily in Africa and Asia, the double rifle is a sporting weapon with very little military heritage. Design The double rifle is usually handcrafted and is considered by many to be the pinnacle of sporting rifle design. It is not designed for long-range accuracy but instead for the security of an immediate second shot. Double rifles are similar to double-barreled shotguns. Action As with double-barrelled shotguns, modern double rifles are all made with either sidelock or boxlock actions, although occasionally old hammer rifles can be found. The majority of double rifles have been built on the boxlock actions as it is a simpler design with fewer moving parts that can fail. Consequently, it has an outstanding reputation for reliability. The sidelock actio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-shot
In firearm designs, the term single-shot refers to guns that can hold only a single round of ammunition inside and thus must be reloaded manually after every shot. Compared to multi-shot repeating firearms ("repeaters"), single-shot designs have no moving parts other than the trigger (firearms), trigger, hammer (firearms), hammer/firing pin or frizzen, and therefore do not need a sizable receiver (firearms), receiver behind the gun barrel, barrel to accommodate a moving action (firearms), action, making them far less complex and more robust than revolvers or magazine (firearm), magazine/ammunition belt, belt-fed firearms, but also with much slower rate of fire, rates of fire. The history of firearms began with muzzleloader, muzzleloading single-shot firearms such as the hand cannon and arquebus, then multiple-barrel firearm, multi-barreled designs such as the derringer appeared, and eventually many centuries passed before breechloading repeating firearms became commonplace.

Breech-loading
A breechloader is a firearm in which the user loads the ammunition from the breech end of the barrel (i.e., from the rearward, open end of the gun's barrel), as opposed to a muzzleloader, in which the user loads the ammunition from the ( muzzle) end of the barrel. The vast majority of modern firearms are generally breech-loaders, while firearms made before the mid-19th century were mostly smoothbore muzzle-loaders. Only a few muzzleloading weapons, such as mortars, rifle grenades, some rocket launchers, such as the Panzerfaust 3 and RPG-7, and the GP series grenade launchers, have remained in common usage in modern military conflicts. However, referring to a weapon explicitly as breech-loading is mostly limited to weapons where the operator loads ammunition by hand (and not by operating a mechanism such as a bolt-action), such as artillery pieces or break-action small arms. Breech-loading provides the advantage of reduced reloading time because it is far quicker to load ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Musket
A musket is a muzzle-loaded long gun that appeared as a smoothbore weapon in the early 16th century, at first as a heavier variant of the arquebus, capable of penetrating plate armour. By the mid-16th century, this type of musket gradually disappeared as the use of heavy armour declined, but ''musket'' continued as the generic term for smoothbore long guns until the mid-19th century. In turn, this style of musket was retired in the 19th century when rifled muskets (simply called rifles in modern terminology) using the Minié ball (invented by Claude-Étienne Minié in 1849) became common. The development of breech-loading firearms using self-contained Cartridge (firearms), cartridges, introduced by Casimir Lefaucheux in 1835, began to make muskets obsolete. The first reliable repeating rifles, the 1860 Henry rifle and its 1866 descendent the Winchester rifle, superseded muskets entirely. Repeating rifles quickly established themselves as the standard for rifle design, ending the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
