The identifying feature of centerfire ammunition is the metal cup containing the primer inserted into a recess in the center of the base of the cartridge. The firearm firing pin crushes this explosive between the cup and an anvil to produce hot gas and a shower of incandescent particles to ignite

364-526: A boxed SA, as well as many other parts produced in those countries and barrels produced in Finland, Switzerland, Austria, Belgium and Germany. The Finns also manufactured two-piece "finger splice" stocks for their Mosin–Nagant rifles. In addition, the rifle was distributed as aid to Republican anti- Franco forces in the Spanish Civil War . Spanish Civil War Mosins can be readily identified by

455-556: A falling-off in finish of the rifles. The wartime Mosins are easily identified by the presence of tool marks and rough finishing that never would have passed the inspectors in peacetime. However, despite a lack of both aesthetic focus and uniformity, the basic functionality of the Mosins was unimpaired. In addition, in 1938 a carbine version of the Mosin–Nagant, the M38, was issued. It used

546-427: A firearm of any sort is igniting the propellant. The earliest firearms were hand cannons , which were simple closed tubes. There was a small aperture, the "touchhole", drilled in the closed end of the tube, leading to the main powder charge. This hole was filled with finely ground powder, which was then ignited with a hot ember or torch . With the advent of hand-held firearms, this became an undesirable way of firing

637-453: A gun. Holding a burning stick while trying to pour a charge of black powder carefully down a barrel is dangerous, and trying to hold the gun with one hand while simultaneously aiming at the target and looking for the touchhole makes it very difficult to fire accurately. The first attempt to make the process of firing a small arm easier was the "matchlock". The matchlock incorporated a "lock" (so-called because of its resemblance to door locks of

728-423: A hot ember at the burning end. 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. This brought the match down to the touchhole, igniting the powder. With careful attention, the slow-burning match could be kept burning for long periods of time, and

819-408: A measured charge of powder and a bullet in one convenient package; the paper also served to seal the bullet in the bore. Still, the source of ignition was handled separately from the cartridge. With the advent of chemical primers, it was not long before several systems were invented with many different ways of combining bullet, powder, and primer into a single package which could be loaded quickly from

910-613: A mechanical impact. The primer in turn ignites the main propellant, just as with a shock-sensitive or external electric type. Among the advantages this brings is the ability, in an automatic weapon, to control the moment of cartridge ignition partially independently of the mechanical action of the gun. Historically this flexibility was employed by the German Luftwaffe in WW II, in the unusually efficient synchronization gear that enabled machine guns and autocannon to be fired through

1001-410: A more complicated mechanism and a long and tiresome procedure of disassembling (which required special instruments—it was necessary to unscrew two fasteners). Mosin's rifle was mainly criticized for its lower quality of manufacture and materials, due to "artisan pre-production" of his 300 rifles. The commission initially voted 14 to 10 to approve Mosin's rifle. At this point the decision was made to rename

1092-482: A much faster lock time. It never became a popular sporting arms system and was discontinued by Remington as a result. Primer-actuated firearms use the energy of primer setback to unlock and cycle the firearm. John Garand developed the system in an unsuccessful bid to replace the M1903 bolt-action rifle in the early 1920s. Garand's prototypes worked well with US military .30-06 ammunition and uncrimped primers, but then

1183-476: A new .17 caliber cartridge based on the .22 WMR, the .17 HMR . The .17 HMR is essentially a .22 WMR cartridge necked down to accept a .17-caliber bullet and is used as a flat-shooting, light-duty varmint round. The .17 HMR was followed up by Hornady's .17 Mach 2, or .17 HM2 in 2003, which is based on a slightly lengthened and necked-down .22 Long Rifle cartridge. Both of these .17 caliber rimfire cartridges have had widespread support from firearms makers, and while

1274-577: A patent since he was an officer of the Russian army, and the design of the rifle was owned by the Government and had the status of a military secret. A scandal was about to burst out, with Nagant threatening he would not participate in trials held in Russia ever again and some officials proposing to expel Nagant from any further trials, as he borrowed the design of the interrupter after it was covered by

1365-419: A simpler, more robust design. The "flintlock", like the wheel-lock, used a flashpan and a spark to ignite the powder. As the name implies, the flintlock used flint rather than iron pyrite. The flint was held in a spring-loaded arm, called the "cock" from the resemblance of its motion to a pecking chicken. The cock rotated through approximately a 90-degree arc and was held in the tensioned, or "cocked" position by

1456-425: A source of heat , it could be kept ready for extended periods of time. The covered flashpan also provided some ability to withstand bad weather. Wind, rain, and wet weather would render a matchlock useless, but a wheel-lock that was loaded and waterproofed with a bit of grease around the flashpan could be fired under most conditions. The wheel-lock enjoyed only a brief period of popularity before being superseded by

1547-522: A split rear receiver ring, also serving a similar function to Mauser's "third" or "safety" lug. The rifling of the Mosin barrel is right turning (clockwise looking down the rifle) 4-groove with a twist of 1:9.5" or 1:10". The 5-round fixed metallic magazine can either be loaded by inserting the cartridges individually, or more often in military service, by the use of 5-round stripper clips . The 3-line rifle, Model 1891 , its original official designation,

1638-421: A trigger. Usually, flintlocks could lock the cock in two positions. The "half-cock" position held the cock halfway back, and used a deep notch so that pulling the trigger would not release the cock. Half-cock was a safety position, used when loading, storing or carrying a loaded flintlock. The "full-cock" position held the cock all the way back and was the position from which the gun was fired. The L-shaped "frizzen"

1729-522: A variety of self-consuming cartridges before acknowledging that the advantages of brass cases far outweighed their one drawback. The three systems of self-contained metallic cartridge ignition which have survived the test of time are the rimfire , the Berdan centerfire primer, and the Boxer centerfire primer. A pinfire firearm cartridge is an obsolete type of brass cartridge in which the priming compound

1911-420: Is ignited by striking a small pin which protrudes radially from just above the base of the cartridge. Invented by Casimir Lefaucheux in 1828, but not patented until 1835, it was one of the earliest practical designs of a metallic cartridge. However, the protruding pin was vulnerable to damage, displacement and accidental ignition. Moreover, the pin had to be positioned carefully in a small notch when loading, making

2002-427: Is placed in the shell and simply spun around to cover the full extremes of the rim. (For more on the exact process and one set of chemical compounds that have been used successfully, see U.S. patent 1,880,235 , a 1932 Remington Arms patent by James E. Burns.) In the dry state, the primer within the rim becomes impact-sensitive. When the rim is then crushed by the hammer or firing pin, the primer detonates and ignites

2093-533: Is primarily found chambered for its original 7.62×54mmR cartridge . Developed from 1882 to 1891, it was used by the armed forces of the Russian Empire , the Soviet Union and various other states. It is one of the most mass-produced military bolt-action rifles in history, with over 37 million units produced since 1891. In spite of its age, it has been used in various conflicts around the world up to

2184-432: Is the most popular recreational caliber today because it is inexpensive, relatively quiet, and has very low recoil . While the rimfire priming method is limited due to the thin cases required, it has enjoyed a few resurgences recently. First, it was Winchester's .22 Magnum Rimfire, or .22 WMR in 1959, followed in 1970 by Remington's short-lived 5mm Rimfire , based on Winchester's magnum case. In 2002, Hornady introduced

2275-510: Is used in the spotting rifles on the LAW 80 and Shoulder-launched Multipurpose Assault Weapon use a 9mm, .308 Winchester -based cartridge with a .22 Hornet blank cartridge in place of the primer. Upon firing, the Hornet case sets back a short distance, unlocking the action. Primer-actuated cartridges/piston primer cartridges use a primer in the form of a blank to contain the propellant within

2366-550: The 1937 World Shooting Championships in Helsinki. M/28–30 model, serial number 60974, was also used by Simo Häyhä , a well-known Finnish sniper. M/28–30 was used as Civil Guards competition rifle before World War II, as was the case with Simo Häyhä's personal rifle. Therefore, rifles were built very well, with highest grade barrels available and carefully matched headspace. Häyhä's rifle was still at PKarPr (Northern Karelia Brigade) museum in 2002, then moved to an unknown place by

2457-708: The AK series rifles. Despite its increasing obsolescence, the Mosin–Nagant saw continued service throughout the Eastern bloc and the rest of the world for many decades to come. Mosin–Nagant rifles and carbines saw service on many fronts of the Cold War , from Korea and Vietnam to Afghanistan and along the Iron Curtain in Europe. They were kept not only as reserve stockpiles, but front-line infantry weapons as well. Finland

2548-484: The American Civil War , as it was simpler and more reliable than the flintlock. The main reason the caplock was so quickly adopted was its similarity to the flintlock and the ease of converting older arms to use percussion-cap ignition; usually, the same lock and barrel could be used with minor changes. The flashpan and frizzen were removed and replaced by a small, hollow horizontal cylinder (drum) screwed into

2639-807: The Czechoslovak Legions in Siberia to aid in their attempt to secure passage to France. Many of the New England Westinghouse and Remington Mosin–Nagants were sold to private citizens in the United States before World War II through the office of the Director of Civilian Marksmanship, the predecessor to the federal government's current Civilian Marksmanship Program . Large numbers of Mosin–Nagants were captured by German and Austro-Hungarian forces and saw service with

2730-583: The Mauser locks vertically. The Mosin bolt body is multi-piece whereas the Mauser is one piece. The Mosin uses interchangeable bolt heads like the Lee–Enfield . Unlike the Mauser, which uses a controlled feed bolt head in which the cartridge base snaps up under the fixed extractor as the cartridge is fed from the magazine, the Mosin has a push feed recessed bolt head in which the spring-loaded extractor snaps over

2821-743: The Ministry of War of the Russian Empire , and in 1889 the Lebel Model 1886 rifle was obtained through semi-official channels from France. It was supplied together with a model of the cartridge and bullet but without primer or smokeless powder . Those problems were solved by Russian scientists and engineers (the smokeless powder, for instance, was produced by Dmitri Mendeleev himself). In 1889, three rifles were submitted for evaluation: Captain Sergei Ivanovich Mosin of

2912-440: The breech of the firearm. This greatly streamlined the reloading procedure and paved the way for semi- and fully automatic firearms. This big leap forward came at a price. It introduced an extra component into each round – the cartridge case - which had to be removed before the gun could be reloaded. While a flintlock, for example, is immediately ready to be reloaded once it has been fired, adopting brass cartridge cases brought in

3003-431: The firing pin , or electrically ignited, primers react chemically to produce heat, which gets transferred to the main propellant charge and ignites it, and this, in turn, propels the projectile. Due to their small size, these primers themselves lack the power to shoot the projectile, but still have enough energy to drive a bullet partway into the barrel — a dangerous condition called a squib load . The first step to firing

3094-773: The American .30-06 Springfield cartridge. With the fall of the Iron Curtain , a large quantity of Mosin–Nagants have found their way onto markets outside of Russia as collectibles and hunting rifles. Due to the large surplus created by the Soviet small arms industry during World War II and the tendency of the former Soviet Union to retain and store large quantities of old but well-preserved surplus (long after other nations' militaries divested themselves of similar vintage materials), these rifles (mostly M1891/30 rifles and M1944 carbines) are inexpensive compared to other surplus arms of

3185-505: The Berdan rifles then in use by the Russian army. The Mosin rifle was first tested in combat in 1893, during clashes between Russian and Afghan troops in the Pamirs. The Russo-Japanese War (1904–1905) was the rifle's first major conflict. By the time the war broke out in 1904, approximately 3.8 million had been built, with over 1.5 million in the hands of the Russian cavalry and all of its reserves when hostilities commenced. Between

3276-831: The Donbas, and to conscripted Russian civilians as part of Vladimir Putin's wider general mobilization during the 2022 Russian invasion of Ukraine . After the Estonian War of Independence, Estonia had around 120,000 M/1891s in stock, later the Kaitseliit , the Estonian Defence League , received some Finnish M28/30 rifles, a few modernised variants were also made by the Estonian Armory; Most Finnish rifles were assembled by SAKO , Tikkakoski Oy, or VKT ( Valtion Kivääritehdas , State Rifle Factory, after

3367-515: The Finnish Army. Mosin–Nagants have been exported from Finland since the 1960s as its military modernized and decommissioned the rifles. Most of these have ended up as inexpensive surplus for Western nations. In the USSR surplus military carbines (without bayonet) were sold as civilian hunting weapons. Also, the Mosin–Nagant action has been used to produce a limited number of commercial rifles,

3458-532: The Mauser, the bolt lift arc on the Mosin–Nagant is 90 degrees, versus 60 degrees on the Lee–Enfield. The Mauser bolt handle is at the rear of the bolt body and locks behind the solid rear receiver ring. The Mosin bolt handle is similar to the Mannlicher : it is attached to a protrusion on the middle of the bolt body, which serves as a bolt guide, and it locks protruding out of the ejection/loading port in front of

3549-661: The Mosin–Nagant (Russia had not paid for the order at any time throughout the Great War). With Remington and Westinghouse on the precipice of bankruptcy from the Communists' decision, the remaining 280,000 rifles were purchased by the United States Army . American and British expeditionary forces of the North Russia Campaign were armed with these rifles and sent to Murmansk and Arkhangelsk in

3640-529: The Mosin–Nagant as a sniper rifle, with similar success with their own designs and captured Soviet rifles. For example, Simo Häyhä is credited with having killed 505 Soviet soldiers, many of whom fell victim to his Finnish M/28-30 derivative. Häyhä did not use a scope on his Mosin. In interviews Häyhä gave before his death, he said that the scope and mount designed by the Soviets required the shooter to expose himself too much and raise his head too high, increasing

3731-789: The Mosin–Nagant, all of them manufactured using the receivers of Russian-made, American-made, French-made or (later) Soviet-made rifles. Finland also utilized a number of captured M91 and M91/30 rifles with minimal modifications. As a result, the rifle was used on both sides of the Winter War and the Continuation War during World War II. Finnish Mosin–Nagants were produced by SAKO , Tikkakoski, and VKT, with some using barrels imported from Switzerland and Germany. In assembling M39 rifles, Finnish armorers reused "hex" receivers that dated back as far as 1891. Finnish rifles are characterized by Russian, French or American-made receivers stamped with

3822-516: The United States in 1915. Remington produced 750,000 rifles before production was halted by the 1917 October Revolution . Deliveries to Russia had amounted to 469,951 rifles when the Treaty of Brest-Litovsk ended hostilities between the Central Powers and now Soviet-Russia. Henceforth, the new Bolshevik government of Vladimir Lenin cancelled payments to the American companies manufacturing

3913-854: The Western press. From a technical point of view the rifle that came to be called "Mosin–Nagant" is the design proposed by Mosin as further amended by Mosin with some details borrowed from Nagant's design. Only since 1924 the rifle was officially named "Mosin's rifle" in the USSR, although some variants were still known only by their year of origin. In 1889 Tsar Alexander III ordered the Russian army to meet or exceed European standards in rifle developments with "rifles of reduced caliber and cartridges with smokeless powder". The new weapons would entail "high velocities", exceeding 600 metres per second (2,000 ft/s) and would result in land battles both commencing and being capable of being fought at longer ranges, nearly two kilometers. The new Mosin rifles would replace

4004-568: The adoption of the final design in 1891 and the year 1910, several variants and modifications to the existing rifles were made. With the start of World War I , production was restricted to the M1891 dragoon and infantry models for the sake of simplicity. Due to the desperate shortage of arms and the shortcomings of a still-developing domestic industry , the Russian government ordered 1.5 million M1891 infantry rifles from Remington Arms and another 1.8 million from New England Westinghouse Company in

4095-477: The bolt, but not enough to prevent interchangeability with the earlier Model 1891 and the so-called "Cossack dragoon" rifles. Finland was a Grand Duchy in the Russian Empire until 1917, so Finns had long used the Mosin–Nagant in service with the Imperial military. The rifle was used in the short Finnish Civil War and adopted as the service rifle of the new republic's army. Finland produced several variants of

4186-460: The bored-out and tapped flash hole and carrying a "nipple" over which the cap could be fitted. A "hammer" which also had half-cock (for loading and applying the cap) and full-cock positions replaced the cock. When released by pulling the trigger, the hammer would strike the cap, crushing it against the nipple. The percussion cap was a thin metal cup that contained a small quantity of pressure-sensitive explosive, often mercury fulminate . When crushed,

4277-510: The cartridge base as the bolt is finally closed similar to the Gewehr 1888 and M91 Carcano or modern sporting rifles like the Remington 700 . Like the Mauser, the Mosin uses a blade ejector mounted in the receiver. The Mosin bolt is removed by simply pulling it fully to the rear of the receiver and squeezing the trigger, while the Mauser has a bolt stop lever separate from the trigger. Like

4368-422: The chances of being spotted by the enemy. In addition, scopes tended to reflect sunlight when moved side to side, which gave away a sniper's position. In 1935–1936, the 91/30 was again modified, this time to lower production time. The "hex" receiver was changed to a round receiver. When war with Germany broke out, the need to produce Mosin–Nagants in vast quantities led to a further simplification of machining and

4459-408: The day) that was actuated by a trigger , originally called a "tricker." The lock was a simple lever which pivoted when pulled and lowered the match down to the touchhole. The match was a slow-burning fuse made of plant fibers that were soaked in a solution of nitrates , charcoal , and sulfur , and dried. This "slow-match" was ignited before the gun was needed, and it would slowly burn, keeping

4550-416: The existing commission and call it Commission for creation of the small-bore rifle ( Комиссия для выработки образца малокалиберного ружья ), and to put on paper the final requirements for such a rifle. The inventors obliged by delivering their final designs. Head of the commission, General Chagin, ordered subsequent tests held under the commission's supervision, after which the bolt-action of Mosin's design

4641-463: The explosive decomposes into gas. Cartridges for military use require stable priming formulations, so war reserves of small-arms ammunition will dependably function after years of storage. Some machine gun and autocannon cartridges (such as the MG 131 13mm and M61 Vulcan 20mm) utilize an internal electric primer that contains chemicals activated by an externally provided electric charge, as opposed to

4732-512: The explosive would detonate, sending a stream of hot gas down through a hole in the nipple and into the touchhole of the gun to ignite the powder charge. In the process of firing, the cap generally split open and would fall off when the hammer was moved to the half-cock position for loading. The caplock system worked well, and is still the preferred method of ignition for hunters and recreational shooters who use muzzle-loading arms. A small number of caseless cartridges use no primer at all, but

4823-458: The flashpan to the spark. The flintlock mechanism was simpler and stronger than the wheel-lock, and the flint and steel provided a good, reliable source of ignition. The flintlock remained in military service for over 200 years, and flintlocks are still made today for historical re-enactments and muzzle-loading target competition, and for hunters who enjoy the additional challenge that the flintlock provides. The next major leap in ignition technology

4914-573: The front lines. Significantly, the front sight of the M38 was positioned in such a way that the Model 91/30's cruciform bayonet could not be mounted to the muzzle even if a soldier obtained one. An increase in urban combat led directly to the development of the Model M44 Mosin. In essence, the M44 is an M38 with a slightly modified forearm and with a permanently mounted cruciform bayonet that folds to

5005-625: The hands of Soviet, Afghan and Mujahadeen forces in Afghanistan during the Soviet Afghan War of the 80s and the following civil wars of the late 1980s and 90s. Their use in Afghanistan continued on well into the 1990s and the early 21st century by Northern Alliance forces. Mosin–Nagant rifles are still found on modern battlefields around the world. Russia has issued the rifle to conscripts from both occupied regions of

5096-465: The high-tech, high-velocity .17 caliber jacketed bullets make the .17 Rimfire cartridges quite a bit more expensive than the .22 caliber versions, they are excellent for shorter-range shooting and still far less expensive than comparable centerfire cartridges. In 2013, Winchester released the .17 Winchester Super Magnum , which utilizes the larger case of the long-obsolete .25 Stevens allowing for velocities approaching 3,000 ft/s (910 m/s) with

5187-490: The imperial army submitted his "3-line" caliber (.30 cal, 7.62 mm ) rifle; Belgian designer Léon Nagant submitted a "3.5-line" (.35 caliber, 9 mm) design; and a Captain Zinoviev submitted another "3-line" design (1 " line " = 1 ⁄ 10  in or 2.54 mm, thus 3 lines = 7.62 mm). When trials concluded in 1891, the evaluators were split in their assessment. The main disadvantages of Nagant's rifle were

5278-498: The late summer of 1918 to prevent the large quantities of munitions delivered for Tsarist forces from being captured by the Central Powers. Remaining rifles were used for the training of U.S. Army troops. Some were used to equip U.S. National Guard , SATC , and ROTC units. Designated "U.S. Rifle, 7.62mm, Model of 1916", these are among the rarest of American service arms. In 1917, 50,000 rifles were sent via Vladivostok to

5369-669: The military changed from a fast-burning gunpowder to a progressive-burning Improved Military Rifle (IMR) powder. The slower pressure rise made the primer-actuated prototypes unreliable, so Garand abandoned the design for a gas-operated rifle that became the M1 Garand . AAI Corporation used a primer piston in a rifle submitted for the SPIW competition. Other rifles to use this system were the Postnikov APT and Clarke carbine as described in U.S. patent 2,401,616 . A similar system

Rifles in 6.5×54mmR use a necked-down 7.62×54mmR cartridge and were the standard rifle of the USSR's Olympic biathlon team until the International Olympic Committee revised

5551-524: The moving propellers of their fighter aircraft with a relatively small compromise in the guns' output of automatic fire. Other countries such as the Soviet Union relied on cruder mechanical systems, which reduced the rate of fire of their guns more severely. Electric priming was also used in the EtronX system developed and sold by Remington for some of its sporting rifles. It was sold as a firearm with

The Tsar himself dashed

5733-409: The pinfire's use in repeating or self-loading weapons impossible. The pinfire survives today only in a few very small blank cartridges designed as noisemakers and in novelty guns. Rimfire cartridges use a thin brass case with a hollow bulge, or rim, around the back end. This rim is filled during manufacture with an impact-sensitive primer. In the wet state, the primer is stable; a pellet of wet primer

5824-481: The powder charge. Berdan and Boxer primers are used in centerfire cartridges; the primers differ in construction. Various priming mixtures have been used in different sized primers to effect prompt ignition of the powder charge. Particles with relatively high heat capacity are required to promptly ignite smokeless powder deterrent coatings. Some priming explosives decompose into incandescent solids or liquids. Inert ingredients may be heated into incandescent sparks when

5915-479: The powder charge. Rimfire cartridges are usually single-use and normally cannot be reloaded. Also, since the rim must be thin enough to be easily crushed, the peak pressure possible in the case is limited by the strength of this thin rim. Rimfire cartridges originally were available in calibers up to 1 in (25 mm) caliber, however, all but the .22 in (5.6 mm) calibers and smaller eventually became obsolete. The .22 Long Rifle , also fired in pistols ,

6006-495: The present day. During the Russo-Turkish War (1877–1878) , Imperial Russian troops armed mostly with single-shot Berdan rifles suffered heavy casualties against Ottoman troops equipped with Winchester 1866 repeating rifles , particularly at the bloody Siege of Pleven . This showed Russian commanders the need to modernize the general infantry weapon of the army. Various weapons were acquired and tested by GAU of

6097-574: The primary propellant is ignited using an externally provided electric charge, such as with the Voere VEC-91 and the O'Dwyer VLe. This is not to be confused with an electrically ignited internal primer (see below). Chemical primers, advanced metallurgy and manufacturing techniques all came together in the 19th century to create an entirely new class of firearm — the cartridge arm. Flintlock and caplock shooters had long carried their ammunition in paper cartridges , which served to hold

6188-572: The primer is usually of the first type and integrated into the base of a cartridge. Examples include handgun cartridges , rifle cartridges , and shotgun shells . Larger artillery pieces in contrast typically use electric priming. In artillery the primers are frequently a separate component, placed inside the barrel to the rear of the main propellant charge—but there are other examples of guns, including for example some automatic weapons, designed to shoot cartridges with integral electric primers. Upon being struck with sufficient force generated by

6279-437: The problems of extraction and ejection. The mechanism of a modern gun not only must load and fire the piece, but also must remove the spent case, which may require just as many moving parts. Many malfunctions involve this process, either through failure to extract a case properly from the chamber or by allowing it to jam the action. Nineteenth-century inventors were reluctant to accept this added complication and experimented with

6370-616: The rear-echelon forces of both armies, and also with the Imperial German Navy . Many of these weapons were sold to Finland in the 1920s. During the Russian Civil War , infantry and dragoon versions were still in production, though in dramatically reduced numbers. The rifle was widely used by all belligerents in the civil war. In 1924, following the victory of the Red Army , a committee was established to modernize

6461-475: The rifle, which had by then been in service for over three decades. This effort led to the development of the Model 91/30 rifle, which was based on the design of the original dragoon version. The barrel length was shortened by 7 cm (2.8 in). The sight measurements were converted from arshins to meters; and the front sight blade was replaced by a hooded post front sight less susceptible to being knocked out of alignment. There were also minor modifications to

6552-530: The right when it is not needed. It was an improvement on the Model 91/30, particularly for urban warfare; but few M44s saw combat on the Eastern Front. By the end of the war, approximately 19.8 million Mosin–Nagant rifles had been produced. In the years after World War II, the Soviet Union ceased production of all Mosin–Nagants and withdrew them from service in favor of the SKS series carbines and eventually

6643-431: The rules of the event to reduce the range to 50 meters and required all competitors to use rifles chambered in .22 LR. A number of the Model 1891s produced by New England Westinghouse and Remington were sold to private citizens in the United States by the U.S. government through the Director of Civilian Marksmanship Program in the interwar period. Many of these American-made Mosin–Nagants were rechambered by wholesalers to

6734-438: The same cartridge and action as other Mosins, but the barrel was shortened by 21.6 cm (8.5 in) to bring the weapon down to an overall length of 101.6 cm (40.0 in), with the forearm shortened in proportion. The idea was to issue the M38 to troops such as combat engineers , signal corps, and artillerymen, who could conceivably need to defend themselves from sudden enemy advances, but whose primary duties lay behind

6825-416: The same era. Primer (firearms) In early black powder guns such as muzzleloaders , the primer was essentially the same chemical as the main propellant (albeit usually in a finer-powdered form), but poured into an external flash pan , where it could be ignited by an ignition source such as a slow match or a flintlock , though some muzzleloaders have primers like cap gun caps. This external powder

6916-480: The secrecy status given in Russia of that time to military inventions and therefore violated Russian law. Taking into consideration that Nagant was one of the few producers not engaged by competitive governments and generally eager to cooperate and share experience and technology, the Commission paid him a sum of 200,000 Russian rubles, equal to the premium that Mosin received as the winner. The rifle did not receive

7007-404: The use of the lock mechanism made fairly accurate fire possible. The next revolution in ignition technology was the "wheel-lock". It used a spring-loaded, serrated steel wheel which rubbed against a piece of iron pyrite , similar to a modern lighter . 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

7098-577: The wars part of Valtion Metallitehtaat (Valmet) , State Metalworks). The Finnish cartridge 7.62×53mmR is a slightly modified variation of the Russian 7.62×54mmR , and is considered interchangeable with 54R. However, the older version of the Finnish military cartridge was loaded with the S-type bullet that had nominal diameter of .308. In 1936 the Finnish Army fielded a new standard service cartridge intended for both machine guns and rifles. This new cartridge

7189-488: The wire sling hangers inserted in the slots in the forearm and buttstock meant to take the Russian "dog collars" for Russian-style slings, so the rifles could accept Western European–style rifle slings. At the beginning of the war, the Mosin–Nagant 91/30 was the standard-issue weapon of Soviet troops. Millions were produced in World War II for use by the largest mobilized army in history. The Mosin–Nagant Model 1891/30

7280-531: The word "Russian" from this document with his own hand. The decision to pay off Nagant proved wise, as he remained the major contractor for the Russian Government, and the Nagant M1895 revolver was subsequently adopted by the Russian army as its main sidearm. However, in spite of the payment, Nagant attempted to use the situation for publicity, resulting in the name "Mosin–Nagant" appearing in

7371-413: Was a modernized design introduced in 1930. Some details were borrowed from Nagant's design. Despite the failure of Nagant's rifle, he filed a patent suit, claiming he was entitled to the sum the winner was to receive. It appeared that Nagant was the first to apply for the international patent protection over the interrupter, although he borrowed it from Mosin's design initially. Mosin could not apply for

7462-561: Was adopted by the Russian military in 1891. Production began in 1892 at the ordnance factories of Tula Arsenal , Izhevsk Arsenal and at Sestroryetsk Arsenal. An order for 500,000 rifles was placed with the French arms factory, Manufacture Nationale d'Armes de Châtellerault . There have been several refinements and variations of the original rifle, the most common being the M1891/30 (commonly referred to as "the 91/30" by shooters), which

7553-719: Was also improved by adding coil spring to minimize very long pre-travel. Following M/39 does not have this improvement. The magazine was also modified to prevent jamming. Magazines were stamped with "HV" ( häiriövapaa , lit.   ' jam free ' ) letters in right side of rifle. Later M/39 uses identical design, but without the "HV" stamp. M/28–30 also have metal sleeve in fore-end of handguard, to reduce barrel harmonics change and to make barrel-stock contact more constant between shots and/or during environmental changes such as moisture and temperature. Later M/39 does not have this upgrade. In addition to its military usage, approximately 440 M/28–30 rifles were manufactured by SAKO for use in

7644-523: Was connected through a small opening at the rear of the gun barrel that led to the main charge within the barrel. As gunpowder will not burn when wet, this made it difficult (or even impossible) to fire these types of weapons in rainy or humid conditions. Modern primers, by contrast, are more specialized and distinct from the main propellant they are designed to ignite. They are of two types, those using shock-sensitive chemicals, and those reliant on chemicals ignited by an electric impulse. In smaller weapons

7735-602: Was loaded with a new bullet designed in 1934–the D-166, which had a nominal diameter of .310. The new service rifle m/39 was designed from the start around the D-166, thus it had nominal barrel diameter of .310. Handloaded cartridges for Finnish rifles should however use a 0.308-inch (7.8 mm) bullet for use with other Finnish Mosin–Nagant variants instead of the 0.310-inch (7.9 mm) one which gives best results in M/39, Soviet and most of other Mosin–Nagant rifles. The trigger

7826-592: Was modified and adapted as a sniper rifle from 1932 onwards, first with mounts and scopes from Germany then with domestic designs ( PE , PEM) from 1931; from 1942 it was issued with 3.5-power PU fixed focus scopes . It served quite prominently in the brutal urban battles on the Eastern Front , such as the Battle of Stalingrad , which made heroes of such snipers as Vasily Zaitsev , Lyudmila Pavlichenko , Ivan Sidorenko , and Roza Shanina . Finland also employed

7917-503: Was ordered into production under the name of 3-line rifle M1891 ( трёхлинейная винтовка образца 1891 года ). The colloquial name "Mosin-Nagant" used in the West is persistent but erroneous, as established in Nagant's legal dispute . Like the Gewehr 98 , the 1891 Mosin uses two front-locking lugs to lock up the action. However, the Mosin's lugs lock in the horizontal position, whereas

8008-459: 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 ", filled with loose powder which led into the touchhole. 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. The wheel-lock was a major innovation — since it did not rely on burning material as

8099-574: Was still producing the M39 Mosin–Nagant in small numbers as late as 1973. Virtually every country that received military aid from the Soviet Union, China, and Eastern Europe during the Cold War used Mosin–Nagants at various times. Middle Eastern countries within the sphere of Soviet influence—Egypt, Syria , Iraq , Afghanistan and Palestinian fighters—have received them in addition to other more modern arms. Mosin–Nagants have also seen action in

8190-410: Was the invention of the chemical primer, or "cap", and the mechanism which used it, called the "caplock". Percussion ignition was invented by Scottish clergyman Rev. Alexander John Forsyth in 1807 but needed further refinements before it was gradually accepted in the 1820s to 1830s. By the middle of the 19th century, the percussion or caplock system was well established. It was adopted by both sides in

8281-408: Was the other half of the flintlock's ignition system. It served as both a flashpan cover and a steel striking surface for the flint. The frizzen was hinged and spring-loaded so that it would lock in the open or closed position. When closed, the striking surface was positioned so that the flint would strike at the proper angle to generate a spark. The striking flint would also open the frizzen , exposing
