United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Remington Arms
–
Remington Arms Company, LLC is an American manufacturer of firearms and ammunition in the United States. It was founded in 1816 by Eliphalet Remington in Ilion, New York, as E. Remington, Remington is Americas oldest gun maker and Its Americas oldest factory that still makes its original product-guns. It is the only U. S. company which produces both firearms and ammunition domestically and is the largest U. S. producer of shotguns, Remington has also developed or adopted more cartridges than any other gun maker or ammunition manufacturer in the world. Additionally its products are distributed in over 60 foreign countries, making its distribution base, Remington Arms is part of the Freedom Group, which is owned by Cerberus Capital Management. Remington built a new plant in Huntsville, Alabama which is now building Modern Sporting Rifles, the Remington company was founded in 1816. Eliphalet Remington II believed he could build a gun than he could buy. Farming communities in the region were famous for their skills and self-sufficiency. Remingtons father was a blacksmith, and wanted to expand his business into rifle barrel production, local residents often built their own rifles to save on costs, but purchased the barrel. Remingtons father sent him to a barrel maker in a major city to purchase a barrel. At the time, the method was to heat and wrap long flat bars of iron around a rod of the caliber desired. By heating and hammering the coiled bars around the central rod, after the young man returned home, his family added a successful barrel making operation to his fathers forge, in Ilion Gorge, New York. Remington began designing and building a rifle for himself. At age 23, he entered a match, though he only finished second. Before Remington left the field day, he had received so many orders from other competitors that he was now officially in the gunsmithing business. By 1828, the moved to nearby Ilion, New York. On March 7,1888, ownership of E. Remington & Sons left possession of the Remington family and was sold to new owners, Marcellus Hartley, at this time the name was formally changed to the Remington Arms Company. The Bridgeport site became the home of Remingtons ammunition plant, in 1912, Remington and Union Metallic Cartridge Company were combined into a single entity, called Remington UMC. In 1915, the plant at Ilion was expanded, and with this expansion became basically the same plant as today, during World War I, Remington produced arms under contract for several Allied powers

Bullet
–
The word bullet is a firearm term. A bullet is a projectile expelled from the barrel of a firearm, the term is from Middle French and originated as the diminutive of the word boulle which means small ball. Bullets are made of a variety of materials and they are available singly as they would be used in muzzle loading and cap and ball firearms, as part of a paper cartridge, and much more commonly as a component of metallic cartridges. Bullets are made in a numbers of styles and constructions depending on how they will be used. Many bullets have specialized functions, such as hunting, target shooting, training, defense, a bullet is not a cartridge. In paper and metallic cartridges a bullet is one component of the cartridge, bullet sizes are expressed by their weight and diameter in both English and Metric measurement systems. For example.22 caliber 55 grain bullets or 5. 56mm 55 grain bullets are the same caliber, the word bullet is often used colloquially to refer to a cartridge, which is a combination of the bullet, paper or metallic case/shell, powder, and primer. This use of bullet, when cartridge is intended, leads to confusion when the components of a cartridge are discussed or intended, the bullets used in many cartridges are fired at a muzzle velocity faster than the speed of sound. Meaning they are supersonic and thus can travel a substantial distance, bullet speed through air depends on a number of factors such as barometric pressure, humidity, air temperature, and wind speed. Subsonic cartridges fire bullets slower than the speed of sound and so there is no sonic crack and this means that a subsonic cartridge such as.45 ACP can be effectively suppressed to be substantially quieter than a supersonic cartridge such as the.223 Remington. Bullets do not normally contain explosives, but damage the target by impact. The first use of gunpowder in Europe was recorded in 1247 and it had been used in China for hundreds of years. Later in 1364 hand cannon appeared, early projectiles were made of stone. Stone was used in cannon and hand cannon, in cannon it was eventually found that stone would not penetrate stone fortifications which gave rise to the use of heavier metals for the round projectiles. Hand cannon projectiles developed in a similar following the failure of stone from siege cannon. The first recorded instance of a ball from a hand cannon penetrating armor occurred in 1425. In this photograph of shot retrieved from the wreck of the Mary Rose which was sunk in 1545, the round shot are clearly of different sizes and some are stone while others are cast iron. The development of the hand culverin and matchlock arquebus brought about the use of cast lead balls as projectiles, bullet is derived from the French word boulette, which roughly means little ball

Primer (firearms)
–
In firearm ballistics, the primer is a component of pistol, rifle, and shotgun rounds. Early primers were simply the same black powder used to fire the weapon and this external powder was connected though a tube in the barrel that led to the main charge. As powder wont burn when wet, this led to difficulty, or even the inability, modern primers are shock sensitive chemicals. In smaller weapons the primer is usually integrated into the rear of a cartridge, in larger weapons like cannon the primer is a separate component placed inside the barrel to the rear of the main propellant charge. The first step to firing a firearm of any sort is igniting the propellant, the earliest firearms were cannons, which were simple closed tubes. There was an aperture, the touchhole, drilled in the closed end of the tube. This hole was filled with finely ground powder, which was ignited with a hot ember or torch. With the advent of firearms, this became an undesirable way of firing a gun. The first attempt to make the process of firing a small arm easier was the matchlock, the matchlock incorporated a lock that was actuated by a trigger, originally called a tricker. The lock was a lever which pivoted when pulled. The match was a burning fuse made of plant fibers that were soaked in a solution of nitrates, charcoal, and sulfur. This slow-match was ignited before the gun was needed, and it would slowly burn, after the gun was loaded and the touchhole primed with powder, the burning tip of the match was positioned so that the lock would bring it into contact with the touchhole. To fire the gun, it was aimed and the trigger pulled and this brought the match down to the touchhole, igniting the powder. With careful attention the slow-burning match could be burning for long periods of time. The next revolution in technology was the wheel-lock. It used a spring-loaded, serrated steel wheel which rubbed against a piece of iron pyrite, a key was used to wind the wheel and put the spring under tension. Once tensioned, the wheel was held in place by a trigger, when the trigger was pulled, the serrated edge of the steel rubbed against the pyrite, generating sparks. These sparks were directed into a pan, called the flash pan, the flashpan usually was protected by a spring-loaded cover that would slide out of the way when the trigger was pulled, exposing the powder to the sparks

Cartridge (firearms)
–
Military and commercial producers continue to pursue the goal of caseless ammunition. A cartridge without a bullet is called a blank, One that is completely inert is called a dummy. Some artillery ammunition uses the same concept as found in small arms. In other cases, the shell is separate from the propellant charge. In popular use, the bullet is often misused to refer to a complete cartridge. The cartridge case seals a firing chamber in all directions excepting the bore, a firing pin strikes the primer and ignites it. The primer compound deflagrates, it does not detonate, a jet of burning gas from the primer ignites the propellant. Gases from the burning powder pressurize and expand the case to seal it against the chamber wall and these propellant gases push on the bullet base. In response to pressure, the bullet will move in the path of least resistance which is down the bore of the barrel. After the bullet leaves the barrel, the pressure drops to atmospheric pressure. The case, which had been expanded by chamber pressure. This eases removal of the case from the chamber, brass is a commonly used case material because it is resistant to corrosion. A brass case head can be work-hardened to withstand the pressures of cartridges. The neck and body portion of a case is easily annealed to make the case ductile enough to allow reforming so that it can be reloaded many times. Steel is used in some plinking ammunition, as well as in military ammunition. Steel is less expensive than brass, but it is not feasible to reload, Military forces typically consider small arms cartridge cases to be disposable, one-time-use devices. However, case weight affects how much ammunition a soldier can carry, conversely, steel is more susceptible to contamination and damage so all such cases are varnished or otherwise sealed against the elements. One downside caused by the strength of steel in the neck of these cases is that propellant gas can blow back past the neck

Rimless cartridge
–
A rim is an external flange that is machined, cast, molded, stamped or pressed around the bottom of a firearms cartridge. Thus, rimmed cartridges are sometimes called flanged cartridges, almost all cartridges feature an extractor or headspacing rim, in spite of the fact that some cartridges are known as rimless cartridges. These types are rimmed, rimless, semi-rimmed, rebated rim and these categories describe the size of the rim in relation to the base of the case. The rimmed cartridge, sometimes called flanged cartridge, is the oldest of the types and has a rim that is larger in diameter than the base of the cartridge. Rimmed cartridges use the rim to hold the cartridge in the chamber of the firearm, because the rimmed cartridge headspaces on the rim, the case length is of less importance than rimless cartridges. This allows some firearms chambered for similar rimmed cartridges to safely chamber and fire shorter cartridges, rimmed cartridges are well suited to certain types of actions, such as revolvers, where the rim helps hold the cartridge in position, and break-action firearms. Semi-automatic handguns have been chambered in rimmed cartridges as well, for example a LAR Grizzly or Desert Eagle in.357 or.44 Magnum, under the metric cartridge designation system, a capitalized R added at the end of the designation denotes a rimmed cartridge. For example,7. 62×54mmR is a cartridge, while 7. 62×51mm is a rimless cartridge.45 Auto Rim. Examples of rimmed handgun cartridges include the.38 Special.357 Magnum, rimmed rifle cartridge examples include the.22 Hornet.303 British and 7. 62×54mmR. Rimless cases are not well suited to break-open and revolver actions, though they can be used with modifications, such as a spring-loaded extractor or, in a revolver. Crimping affects the length of the cartridge, and thus cannot be used on cartridges which headspace on the case mouth. Examples of rimless handgun cartridges include the 9mm Parabellum.40 S&W, rimless rifle examples include the.223 Remington.308 Winchester. 30-06 Springfield and 7. 92×57mm Mauser. On a semi-rimmed case the rim projects slightly beyond the base of the case, the tiny rim provides minimal interference feeding from a box magazine, while still providing enough surface to headspace on. Semi-rimmed cases are less common than the other types, if the chamber is cut shallow, so the case headspaces off the mouth, the rim is used for extraction only, a standard chamber will use the rim for both headspacing and extraction. Examples of more commonly encountered rimless handgun cartridges are.25 ACP.32 ACP and.38 ACP, while the.308 Marlin Express.338 Marlin Express and.444 Marlin are rifle cartridges that are semi-rimmed. Rebated rim cartridges have a rim that is smaller in diameter than the base of the case. Functionally the same as a case, the rebated rim provides some additional benefits when considered in conjunction with other cartridges. One example of a rebated rim cartridge is the.50 Action Express, by using the same rim dimensions as the.44 Magnum, a Desert Eagle could be converted from.44 Magnum to.50 AE by merely changing the barrel and magazine

Remington Model 8
–
The Remington Model 8 is a semi-automatic rifle designed by John Browning and produced by Remington Arms. Originally introduced as the Remington Autoloading Rifle in 1906, the name was changed to the Remington Model 8 in 1911, on October 16,1900, John Browning was granted U. S. Patent 659,786 for the rifle, which he sold to Remington. Outside the U. S. this rifle was made by Fabrique Nationale of Liege, Belgium, under an agreement between Remington and FN, the Model 8 would be sold in the US while the FN1900 would be sold elsewhere. Despite having a market, the FN1900 was sold predominately to hunters in and around Western Europe. Because of the new and yet unproven nature of the autoloading rifle, due to lackluster sales, only 4,913 Model 1900s were ever produced compared to the over 80,000 Model 8s produced. The Remington Model 8 rifle is long recoil-operated and uses a bolt head. After firing, the barrel and bolt, still locked together, move rearward inside the receiver, then the bolt is held back while the barrel is returned forward by one of the springs permitting extraction and ejection. Once the barrel is returned, the bolt is returned forward by the spring, in so doing it picks up a fresh round from the magazine. The Remington Model 8 has a fixed 5-shot magazine and bolt hold-open device which engages after the magazine is empty and it is a takedown design, meaning that the barrel and receiver are easily separated with no tools, allowing for a smaller package for transport. Remington created four new calibers for the Model 8 rifle.25 Remington.30 Remington.32 Remington and these cartridges were rimless designs to allow reliable feeding from box magazines. The Model 8 was offered in five grades of finish and was the first truly reliable medium power semiautomatic rifle ever commercialized, the primary market for the Model 8 was sport hunting. The Model 8 was used as a gun, modified to use detachable extended capacity magazines. It is noted as the rifle of choice of famed Texas Ranger Frank Hamer, hamers rifle was a customized.35 Remington Model 8 with a special-order 15-round magazine from Petmeckeys Sporting Goods store in Austin, Texas. He was shipped serial number 10045, and this was just one of at least two Model 8s used in the ambush of Clyde Barrow and Bonnie Parker. The rifle was modified to accept a police only 20-round magazine obtained through the Peace Officers Equipment Company in St. Joseph, in 1936, Remington dropped the Model 8 and introduced the Model 81 Woodsmaster with improvements by C. C. The Model 81 was offered in.300 Savage and the.25 Remington chambering was dropped after a number of 81s were chambered in this round. It was offered in Standard, Special, Peerless, Expert, the Federal Bureau of Investigation acquired some Model 81 rifles chambered for.30 Remington and.35 Remington in response to the 1933 Kansas City Massacre

Semi-automatic rifle
–
A semi-automatic rifle is a self-loading rifle that fires a single round each time the trigger is pulled. In contrast, an automatic rifle continuously fires rounds as long as the trigger is pressed. The ability to load the next round allowed for an increase in the rounds per minute the operator could fire. These rifles are known as self-loading rifles or auto-loading rifles and are often mistaken for automatic rifles or machine guns. Self-loading rifles were one of the most revolutionary designs in the history of warfare and they can be efficiently fed by en-bloc clip and internal magazine, detachable magazine or a combination of stripper clip and internal magazine. The first successful design for a rifle is attributed to German-born gunsmith Ferdinand Ritter von Mannlicher. The Model 85 was followed by the equally innovative Mannlicher Models 91,93 and 95 semi-automatic rifles.5 mm ammunition that were fed into the M1894 by a stripper clip. The Auto-5 relied on long recoil operation, this remained the dominant form in semi-automatic shotguns for approximately 50 years. Production of the Auto-5 was finally ended in 1999, in 1903 and 1905, the Winchester Repeating Arms Company introduced the first semi-automatic rimfire and centerfire rifles designed especially for the civilian market. The Winchester Model 1903 and Winchester Model 1905 operated on the principle of blowback in order to function semi-automatically, johnson, the Model 1903 achieved commercial success and continued to be manufactured until 1932 when the Winchester Model 63 replaced it. Winchester introduced a medium caliber semi-automatic rifle, the Model 1907 as an upgrade to the Model 1905, utilizing a system of operation. Both the Models of 1905 and 1907 saw limited military and police use, in 1906, Remington Arms introduced the Remington Auto-loading Repeating Rifle. Remington advertised this rifle, renamed the Model 8 in 1911 and this is a locked-breech, long recoil action designed by John Browning. The Model 81 superseded the Model 8 in 1936 and was offered in.300 Savage as well as the original Remington calibers, the first semi-automatic rifle adopted and widely issued by a major military power was the Fusil Automatique Modele 1917. This is a breech, gas-operated action which is very similar in its mechanical principles to the future M1 Garand in the United States. The M1917 was fielded during the stages of WWI but it did not receive a favorable reception. However its shortened and improved version, the Model 1918, gave complete satisfaction during the Moroccan Rif War from 1920 to 1926, the Lebel bolt-action rifle remained the standard French infantry rifle until replaced in 1936 by the MAS-36 despite the various semi-automatic rifles designed between 1918 and 1935. In 1937, the American M1 Garand was the first semi-automatic rifle to replace its nations bolt-action rifle as the infantry weapon

Marlin Model 336
–
The Marlin Model 336 is a lever-action rifle and carbine made by Marlin Firearms. Since its introduction in 1948, it has offered in a number of different calibers and barrel lengths. Currently, the model with a 24-inch barrel is available in. 30-30 Winchester. The Model 336 is currently produced by Remington Arms, the Model 336 is a direct development of the Marlin Model 1893 rifle which was produced from 1893 to 1936. Based on the patents of L. L. Hepburn, the Model 1893 incorporated a new locking bolt system, in 1936, with only minor changes to the stock, forearm, and sights, the Model 1893 was redesignated the Model 1936. All of these featured a solid-top receiver made of forged steel. In 1948, the Model 36 was replaced by the Model 336, an evolution of the Model 36 rifle, the Model 336 is easily distinguished from its predecessors by its open ejection port machined into the side of the receiver. Like its predecessors, the receiver and all working parts of the Model 336 are constructed of steel forgings. With its solid, flat top receiver and side ejection of fired cartridges, in 1956, Marlin also incorporated its proprietary Micro-Groove rifling system into the Model 336 and other centerfire Marlin rifles. This rifling system, which used a number of relatively shallow rifling grooves, cut down production time. According to Marlin, the Micro-Groove system provides very uniform bore dimensions and a smooth bore finish designed to improve accuracy, prevent gas leakage. The Model 336 is designed to be disassembled for cleaning. Removal of the pivot screw with a flathead screwdriver, allows field stripping of the lever arm, bolt. Unlike many lever action designs, the Model 336 can be cleaned from the breech, much like a bolt-action rifle and this in turn avoids damage to the muzzle caused by cleaning rods and tools. As of 1983, the Model 336 was ranked the #2 all-time leader in U. S. high-powered sporting rifle sales, after the Winchester Model 1894, with over 3.5 million sold. Marauder, Trapper, Model 336Y Marlin has made short carbine versions of the Model 336 over the years, including the Model 336 Marauder, Trapper, usually featuring a short 16- or 18-inch barrel, these carbines are considerably shorter and lighter than the standard 20 carbine. Marlin sold these rifles as the Glenfield Models 30, 30A, however, Marlin continued to offer a less expensive version of the Model 336, variously called the Model 336W or Model 30AW, originally sold only to the Wal-Mart chain. Fitted with a stock and lower-cost sights, these rifles were frequently offered as part of a special package with an inexpensive rifle scope, sling

Lever action
–
Lever action is a type of firearm action which uses a lever located around the trigger guard area to load fresh cartridges into the chamber of the barrel when the lever is worked. This contrasts to bolt-action, semi-automatic, or selective-fire weapons, most lever-action firearms are rifles, but some lever-action shotguns and a few pistols have also been made. One of the most famous lever-action firearms is the Winchester Model 1873 rifle, even Colts Mfg. Co. produced 1883 until 18856403 lever-action Colt-Burgess rifles. Mossberg produces the 464 in centerfire. 30-30 and rimfire.22, probably the first lever-action rifles on the market were Colts 1st and 2nd Model Ring Lever rifles, both Cap and ball rifles, produced by the Patent Arms Mfg. Co. Paterson, N. J. -Colts Patent between 1837 and 1841, the ring-lever was located in front of the trigger. This loading-lever, when pulled, would index the cylinder to the next position, the first significant lever-action design was the Spencer repeating rifle, a magazine-fed lever-operated breech-loading rifle designed by Christopher Spencer in 1860. It was fed from a removable seven-round tube magazine, enabling the rounds to be fired one after another, and which, the Henry also placed the magazine under the barrel, rather than in the butt-stock, a trend followed by most tubular magazines since. The Martini–Henry rifle was the rifle of British and Empire forces from the early 1870s to the turn of the 20th century. It was used in areas, either by civilians or by the local military. Variants copying the Martini–Henry mechanism but using more modern cartridges were also produced, john Marlin, founder of Marlin Firearms Company, New Haven, Connecticut, introduced Marlins first lever-action repeating rifle as the Model 1881. This was chambered in rounds such as the 45/70 and 38/55 and its successor was the 1895 solid top design, which we know as the model 336 today. It also gave rise to the Marlin Model 1894, which is still in production today, by the 1890s, lever-actions had evolved into a form that would last for over a century. Both Marlin and Winchester released new model lever-action rifles in 1894, the Marlin rifle is still in production, whereas production of the Winchester 94 ceased in 2006. While externally similar, the Marlin and Winchester rifles are quite different internally, the fledgling Savage Arms Company became well known after the development of its popular hammerless Models 1895 and 1899 lever-action sporting rifles. Unlike most Winchester and the Marlin lever-action rifles, which used a tubular magazine requiring round-nose or flat-nose bullets and this allowed the 99 to use cartridges with spitzer pointed bullets for increased ballistic performance. The 99 was produced in different cartridges and several different model variations. The final models eliminated the very expensive-to-produce rotary magazine, using a box magazine instead. But the 99 was still expensive to produce when compared to the other lever-action rifles
