.30-06 Springfield
–
The.30 refers to the caliber of the bullet, and the 06 refers to the year the cartridge was adopted—1906. It replaced the. 30-03, 6mm Lee Navy, and. 30-40 Krag cartridges and it remains a very popular sporting round, with ammunition produced by all major manufacturers. In the early 1890s, the U. S. military adopted the smokeless powder. 30-40 Krag rimmed cartridge, the 1894 version of that cartridge used a 220-grain round-nose bullet. Around 1901, the U. S. started developing an experimental rimless cartridge for a Mauser action with box magazine and that led to the 1903. 30-03 rimless service round that used the same 220-grain round-nose bullet as the Krag. The. 30-03 achieved a velocity of 2,300 ft/s. Consequently, the round-nosed U. S. 30-03 service cartridge was falling behind. For these reasons, the U. S. military developed a new, lighter, cartridge in 1906, the cartridge was loaded with Military Rifle 21 propellant, and its maximum range was claimed to be 4,700 yd. The M1903 Springfield rifle, which had been introduced alongside the. 30-03 cartridge, was modified to accept the new. 30-06 Springfield cartridge. Modifications to the rifle included shortening the barrel at its breech and resizing the chamber, other changes to the rifle included elimination of the troublesome rod bayonet of the earlier Springfield rifles. The M1906 maximum range was originally overstated, when the M1906 cartridge was developed, the range tests had been done to only 1,800 yards, distances beyond that were estimated, but the estimate for extreme range was wrong by almost 40 percent. The range discrepancy became evident during World War I, before the widespread employment of light mortars and artillery, long-range machine gun barrage or indirect fires were considered important in U. S. infantry tactics. When the US entered World War I, it did not have machine guns, so it acquired British. When those weapons were replaced with US machine guns firing the M1906 round. Firing tests performed around 1918 at Borden Brook Reservoir, Miami, patrone was inroduced in 1914 and used a 197. 5-grain s. S. - schweres Spitzgeschoß boat-tail bullet which had a maximum range of approximately 5,140 yd. Its maximum range was approximately 5,500 yd. Additionally, wartime surplus totaled over 2 billion rounds of ammunition. Army regulations called for training use of the oldest ammunition first, as a result, the older. 30-06 ammunition was expended for training, stocks of.30 M1 Ball ammunition were allowed to slowly grow until all of the older M1906 ammunition had been fired. By 1936, it was discovered that the range of the.30 M1 Ball ammunition with its boat-tailed spitzer bullets was beyond the safety limitations of many ranges. An emergency order was made to manufacture quantities of ammunition that matched the ballistics of the earlier M1906 cartridge as soon as possible

Rifling
–
In firearms, rifling consists of helical grooves in the internal surface of a guns barrel, which impart a spin to a projectile around its long axis. This spin serves to stabilize the projectile, improving its aerodynamic stability. Rifling is often described by its twist rate, which indicates the distance the rifling takes to complete one revolution, such as 1 turn in 10 inches. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will be rotating at a spin rate. Barrels intended for long, small-diameter bullets, such as the ultra-low-drag, 80-grain 0.223 inch bullets, extremely long projectiles such as flechettes may require high twist rates, these projectiles must be inherently stable, and are often fired from a smoothbore barrel. Muskets were smoothbore, large caliber weapons using ball-shaped ammunition fired at low velocity. Due to the high cost and great difficulty of manufacturing, and the need to load readily from the muzzle. Consequently, on firing the ball bounced off the sides of the barrel when fired, barrel rifling was invented in Augsburg, Germany in 1498. In 1520 August Kotter, an armourer of Nuremberg, Germany improved upon this work, though true rifling dates from the mid-16th century, it did not become commonplace until the nineteenth century. The most successful weapons using rifling with black powder were breech loaders such as the Queen Anne pistol, the grooves most commonly used in modern rifling have fairly sharp edges. More recently, polygonal rifling, a throwback to the earliest types of rifling, has become popular, polygonal barrels tend to have longer service lives because the reduction of the sharp edges of the land reduces erosion of the barrel. Supporters of polygonal rifling also claim higher velocities and greater accuracy, polygonal rifling is currently seen on pistols from CZ, Heckler & Koch, Glock, Tanfoglio, and Kahr Arms, as well as the Desert Eagle. Such guns have achieved significant increases in velocity and range. Examples include the South African G5 and the German PzH2000, gain-twist rifling begins with very little change in the projectiles angular momentum during the first few inches of bullet travel after ignition during the transition from chamber to throat. This enables the bullet to remain undisturbed and trued to the case mouth. After engaging the rifling the bullet is progressively subjected to accelerated angular momentum as burning powder propels it down the barrel. By only gradually increasing the rate, torque is spread along a much longer section of barrel. Gain-twist rifling was used as early as the American Civil War, colt Army and Navy revolvers both employed gain-twist rifling

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

Remington Model 700
–
The Remington Model 700 is a series of bolt-action rifles manufactured by Remington Arms since 1962. All are based on the same centerfire bolt action and they often come with a 3-, 4- or 5-round internal magazine depending on caliber, some of which have a floor-plate for quick-unloading, and some of which are blind. The rifle can also be ordered with a box magazine. The Model 700 is available in many different stock, barrel and it is a development of the Remington 721 and 722 series of rifles, which were introduced in 1948. The Remington 700 action is designed for mass production and it is a manually operated bolt action with two forward dual-opposed lugs. The bolt face is recessed, fully enclosing the base of the cartridge, the ejector is a plunger on the bolt face actuated by a coil spring. The bolt is of 3-piece construction, brazed together, the receiver is milled from round cross-section steel. The Remington 700 comes in a number of variants, with different stocks, barrel configurations, metal finishes. In addition, there are three lengths of action, the symmetrical two-lug bolt body has a.695 in diameter. The differing action dimensions influence lock time, the long action has a lock time of 3.0 milliseconds and the short action has a 15% faster lock time of 2.6 milliseconds. To these can be added various magazine configurations, a magazine which has no floorplate, a conventional magazine with detachable floorplate. There are standard consumer versions as well as designed for military. Some variants come with bipods, slings and other accessories, there are several variants of the consumer version of the Model 700, including, Model 700 Model 700 SPS Model 700 ADL Model 700 BDL Model 700 CDL Model 700 VTR Model 700 Safari. Heavy barrel versions with laminated stocks like the Model 700 SPS varmint are available for varmint hunting, the Model 700 ADL was replaced as the most economical Model 700 by the Model 700 SPS in newer production. The 700CDL is usually higher priced than the 700BDL, but has a barrel in comparison. The Mil-Spec refers solely to the 5-R rifling profile designed by Boots Obermeyer and used in the single broach-cut barrels he produces for use in the M24, M40, the contour of the hammer-forged production Remington barrel is much thinner than that used in the M24 and M40 rifle systems. Remington produced a 700 ML muzzleloading rifle from 1996 onward, the EtronX electronic primer ignition system was implemented in the Model 700 EtronX introduced in 2000. There are two models of the 700P – the standard 700P with a 26 heavy barrel and the 700P Light Tactical Rifle which has a 20 fluted heavy barrel

M1903 Springfield
–
It was officially adopted as a United States military bolt-action rifle on June 19,1903, and saw service in World War I. It was officially replaced as the infantry rifle by the faster-firing semi-automatic eight-round M1 Garand starting in 1937. However, the M1903 Springfield remained in service as a standard infantry rifle during World War II. It also remained in service as a rifle during World War II, the Korean War. It remains popular as a firearm, historical collectors piece. Troops armed with outclassed Springfield Model 1892–99 Krag–Jørgensen bolt-action rifles and older single-shot Springfield rifles, the Spanish soldiers inflicted 1,400 U. S. casualties in a matter of minutes. A U. S. Army board of investigation was commissioned as a result of this battle. They recommended replacement of the Krag, the M1903 not only replaced the various versions of the U. S. The two main problems cited with the Krag were its slow-to-load magazine and its inability to handle higher chamber pressures for high-velocity rounds. The United States Army attempted to introduce a higher-velocity cartridge in 1899 for the existing Krags, though a stripper-clip or charger loading modification to the Krag was designed, it was clear to Army authorities that a new rifle was required. In 1882, the bolt action.45 Remington Lee rifle design of 1879, several hundred 1882 Lee Navy Models were also subjected to trials by the U. S. Army during the 1880s, though the rifle was not formally adopted. The Navy adopted the Model 1885, and later different style Lee Model 1895, in Army service, both the 1885 and 1895 6mm Lee were used in the Spanish–American War, along with the.30 Krag and the. 45-70 Model 1873 Springfield. The Lee rifles detachable box magazine was invented by James Paris Lee, other advancements had made it clear that the Army needed a replacement. In 1892, the U. S. military held a series of rifle trials, the Krag officially entered U. S. service in 1894, only to be replaced nine years later by the Springfield M1903. A prototype rifle was produced in 1900, interestingly, it was similar to Rifle No.5. This design was rejected, and a new design combining features of the 1898 Krag rifle, Springfield began work on creating a rifle that could handle higher loads around the turn of the 20th century. Taking a cue from the 1898 Mauser Gewehr 98, a safety lug was added to the side of the bolt behind the extractor. The bolt handle was also bent downwards, to make operation of the bolt faster, the Springfield Model 1901 almost entered production

Pattern 1914 Enfield
–
The Rifle.303 Pattern 1914 was a British service rifle of the First World War period. A bolt action weapon with an integral 5-round magazine, it was principally contract manufactured by companies in the United States and it served as a sniper rifle and as second line and reserve issue until being declared obsolete in 1947. The Pattern 1914 Enfield was the successor to the Pattern 1913 Enfield experimental rifle, during the Boer War the British were faced with accurate long-range fire from Mauser rifles, model 1893 and 1895, in 7×57mm caliber. This smaller, high-velocity round prompted the War Department to develop their own magnum round, the primary contractor was unable to produce more than a handful of rifles, so the P14 became a de facto afterthought. The Short Magazine Lee–Enfield therefore remained the standard British rifle during World War I, shortly afterwards a modification was made to enlarge the bolt lugs and the rifle became the Mark I*. Eventually Winchester would manufacture 235,293 rifles, Remington 400,000 and Eddystone 600,000, when the U. S. entered World War I, the P14 was modified and standardized by the U. S. Ordnance Department and went into production at the factories as had produced the P14, production of that rifle having ceased. Sometimes called the M1917 Enfield, it was chambered for the standard US, in 1926 the Pattern 1914 Enfield was re-designated by the British military as the No3Mk1. Prior to and during World War II, the Pattern 1914 Enfield was used, post Dunkirk and with the great loss of arms that the British forces endured in 1940 the No3Mk1 stock suddenly became a valued resource. The rifle was used again as a sniper rifle, the configuration being different from the World War I incarnation. The Australian Army also used some quantities of the variant of the P14 during World War II. Once sufficient numbers were built up of the Short Magazine Lee–Enfields, the P14/No3Mk1 was declared obsolete in British service in 1947. Adapting the design to fire the standard.303 British round led to the Rifle.303 Pattern 1914, with its prominent sight protection ears on the receiver, dog-leg bolt handle and pot-belly magazine, it was distinctive in appearance. The P14 was a design for the time, and was said to be the most advanced service rifle of World War I. The Pattern 1914 Enfield had a large, strong action. The bolt action had a Model 98 Mauser type claw extractor, the unusual dog-leg bolt handle is low profile and places the knob close to the firers hand, again facilitating rapid fire. Like the Lee–Enfield, the safety falls under the firers thumb, the rifle was designed with a iron sight line consisting of rear receiver aperture battle sight calibrated for. The ladder aperture sight moves vertically on a slide, and hence was not able to correct for wind drift, the front sighting element consisted of a wing guards protected front post, and was adjusted laterally and locked into position during assembly at the arsenal

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

Rifle
–
A rifle is a firearm designed to be fired from the shoulder, with a barrel that has a helical groove or pattern of grooves cut into the barrel walls. The raised areas of the rifling are called lands, which contact with the projectile. When the projectile leaves the barrel, this spin lends gyroscopic stability to the projectile and prevents tumbling and this allows the use of aerodynamically-efficient bullets and thus improves range and accuracy. The word rifle originally referred to the grooving, and a rifle was called a rifled gun, the word rifle is now used for any long hand-held aimed device activated by a trigger, such as Air rifles and the Personnel halting and stimulation response rifle. Rifles are used in warfare, hunting and shooting sports, formerly, rifles only fired a single projectile with each squeeze of the trigger. Modern rifles are capable of firing more than one round per trigger squeeze, some fire in an automatic mode. Thus, modern automatic rifles overlap to some extent in design, in fact, many light machine guns are adaptations of existing automatic rifle designs. A militarys light machine guns are chambered for the same caliber ammunition as its service rifles. Generally, the difference between a rifle and a machine gun comes down to weight, cooling system. Modern military rifles are fed by magazines, while machine guns are generally belt-fed, many machine guns allow the operator to quickly exchange barrels in order to prevent overheating, whereas rifles generally do not. Most machine guns fire from a bolt in order to reduce the danger of cook-off. Machine guns are often crewed by more than one soldier, the rifle is an individual weapon, the term rifle is sometimes used to describe larger crew-served rifled weapons firing explosive shells, for example, recoilless rifles. In many works of fiction a rifle refers to any weapon that has a stock and is shouldered before firing, the origins of rifling are difficult to trace, but some of the earliest practical experiments seem to have occurred in Europe during the 15th century. Archers had long realized that a twist added to the feathers of their arrows gave them greater accuracy. This might also have led to a increase in accuracy. Rifles were created as an improvement in the accuracy of smooth bore muskets, the black powder used in early muzzle-loading rifles quickly fouled the barrel, making loading slower and more difficult. Since musketeers could not afford to take the time to stop and clean their barrels in the middle of a battle, rifles were limited to use by sharpshooters, muskets were smoothbore, large caliber weapons using ball-shaped ammunition fired at relatively low velocity. Due to the high cost and great difficulty of manufacturing, and the need to load readily from the muzzle

M24 Sniper Weapon System
–
The M24 is referred to as a weapon system because it consists of not only a rifle, but also a detachable telescopic sight and other accessories. The M24 SWS has the long action bolt version of the Remington 700 receiver but is chambered for the 7. 62×51mm NATO short action cartridge that has a length of 2.750 inches. The long action allows the rifle to be re-configured for dimensionally larger cartridges up to 3.340 inches in overall length, the M24 originally came tapped for the Leupold Ultra M3A 10×42mm fixed-power scope, which came with a circle-shaped mil-dot glass-etched reticle. This was later replaced in 1998 by the cheaper Leupold Mk 4 LR/T M1 10×40mm fixed-power scope with an elongated-shaped mil-dot wire reticle, the first number is the scopes magnification and the second number in millimeters is the diameter of the objective lens. A fixed power scope has only one magnification and a variable power scope can be adjusted to focus between a range of magnifications, the rifle itself comes with a detachable Harris 9–13 1A2-LM or Harris 9–13 1A2-L bipod unit. The M24 SWS was to be replaced with the M110 Semi-Automatic Sniper System, however, the Army still continued to acquire M24s from Remington until February 2010 and upgraded to the A2 and M24E1 standard in many cases, continuing to serve. The Army chose to upgrade its entire M24 rifle fleet to the M2010 Enhanced Sniper Rifle, Sights, Leupold Ultra M3A 10×42mm fixed power, or Leupold Mk 4 LR/T M3 10×40mm fixed power scope. In 2001 when Remington had the contract to the U. S. military. Redfield was out of business by then, necessitating a change, barrel, Made of 416R stainless steel. The bore twist is 1-turn-in-11.25 inches and the rifling is five radial lands, because of the odd number of lands, none of the lands are 180° apart, i. e. in direct opposition. This results in less bullet deformation, which produces more consistent point of impact, in 5-R rifling, the side of the land is cut at a 65° angle, rather than 90° in conventional rifling. Stock, H-S Precision PST-024, the model with the fixed cheek piece, adjustable LOP, the stock secures the action via an aluminum bedding block to keep it rigid. A twin-strut extension that pulls out of the butt allows a 2-inch adjustment to length-of-pull and this is effected by a thick wheel on a central grooved pillar for adjusting the length and a thin locking ring behind it locks the thick wheel in place. The stock is made from a polymer foam reinforced with fiberglass, carbon fiber. They were rigorously tested before being approved by Remington and the military, accuracy, According to MIL-R-71126, the M24 shall achieve the accuracy results stated below when using M118 Special Ball and fired from a Government approved machine rest. The actual rifle requirements for accuracy were.35 MOA from a machine rest and he stated, Interesting side note was there was a 10,000 round requirement for the barrel to maintain the original accuracy. In fact after some 10,000 round tests we discovered the accuracy improved, a few barrels were tested past 20,000 and accuracy never went below the original accuracy requirement. Maximum effective range is given as 800 meters, but record shots have been made with the M24 at over 1,000 meters, meanwhile, the standard optical sight has a maximum elevation adjustment of 1,000 meters

M2010 Enhanced Sniper Rifle
–
The M2010 Enhanced Sniper Rifle, formerly known as the XM2010 and M24 Reconfigured Sniper Weapon System, is a sniper rifle developed by PEO Soldier for the United States Army. It is derived from the M24 Sniper Weapon System and replaced the existing M24s, after winning a competitive bidding process, Remington was awarded the production contract for up to 3,600 weapons. The Army had anticipated fielding upgraded weapons to deployed U. S. Army Snipers near the end of December 2010, but later expected fielding would happen in January 2011. The U. S. Army developed the system so that the effective range would help snipers in engagements in mountainous. The general penalties for using bigger, more powerful magnum rifle ammunition compared to smaller, standard rifle cartridges are increases in recoil, jump, flash, weight, and barrel wear. The M2010 Enhanced Sniper Rifle differs from 7. 62×51mm NATO chambered M24 Sniper Weapon System in that M2010 sniper weapons are, barreled to a 24 in long,1 in 10 inch twist rate hammer-forged free floating barrel. Fitted with a new assembly that maximizes the amount of physical adjustments for the sniper to provide a better user customized fit. Fitted with a detachable box magazine. The 10 in Titan-QD Fast-Attach suppressor eliminates 98 percent of muzzle flash,60 percent of recoil, fitted with a Leupold Mark 46. The application of advanced corrosion resistant coatings throughout the system, according to Remington Arms each rifle is tested to meet the requirement to fire ≤1 MOA/0.28 mrad before being released for fielding. In 2009 the U. S. government purchased MK248 MOD1.300 Winchester Magnum match-grade ammunition for use in.300 Winchester Magnum sniper rifles like the U. S. Navy Mk13 SWS or reconfigured M24 SWSs. According to the U. S. Navy this ammunition should increase the effective range of. In January 2014, the U. S. Department of Defense annual testing report found that the older A191 or MK248 Mod 0. Live fire tests were conducted in March 2013 against ballistics gelatin, light material barriers and this was the first time the Pentagon’s Director, Operational Test and Evaluation tested the round, which can hit targets out to 1,200 m. The U. S. Army issued three XM2010s to snipers at the United States Army Sniper School on 18 January 2011 and began using the rifle in combat in Afghanistan in March 2011. The XM2010s.300 Win Mag round extends the engagement range over the M24 from 800 meters to 1,200 meters, enhancing lethality and standoff. The Barrett M107.50 caliber rifle can hit targets past 2,000 meters and this was acceptable for material targets, but not individual personnel. The XM2010 addressed the problem and gave increased range over the M24, Remington had been awarded a $28 million on 20 September 2010 to rebuild 3,600 M24 rifles, but only 250 had been ordered to be changed by the time the first XM2010s were fielded

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

Remington Model 513
–
The Remington Model 513 Matchmaster is a bolt-action rifle, manufactured from 1940 to 1968. Since the rifle was designed for shooting, it came equipped with a sturdy half stock with sling swivels, a beavertail fore end. Matchmaster barrels were a 27 heavy target semi-floating type, the patented Matchmaster trigger mechanism had an adjustable stop. The Matchmaster was made to only the. 22-caliber Long Rifle cartridge from a detachable magazine. Civilian versions of the Matchmaster have a finish, while those made for U. S. Army. A letter code was stamped on the side of the barrel. Usually the two letters indicate the month and year in which the rifle was manufactured. The first and/or fourth characters are inspectors stamps, the serial number of the rifle was stamped on the underside of the barrel, just forward of the stock. Model 513T rifles came equipped with Redfield aperture sights, 27-inch heavy barrel, target stock made of American Walnut, the T suffix indicates that the rifle was the target model, originally equipped with target sights. The S variant is medium-weight sporter rifle, Model 513TS or 513S rifles were sporter models equipped with regular sporting-style sights. The S had a barrel, a ramp or post front sight. The Model 513TX was set up for a scope and came with no sights, there was a contract from the government to Remington for 10,000.22 target rifles in 1940. During World War II, 513T rifle were used by the Army for training purposes and this included issue to DCM affiliated clubs for training juniors, and to ROTC units. Those rifles that were purchased by the Army were stamped U. S, PROPERTY on the barrel and the receiver. According to the Remington website, approximately 137,302 Model 513s were manufactured, today Remington 513T Matchmasters are still being used in smallbore competitions and are worth from $200 to $700, depending on their condition.
