56-569: The GP-25 Kostyor ("Bonfire"), GP-30 Obuvka ("Shoe") and GP-34 are a family of Russian 40 mm under-barrel muzzleloaded grenade launchers for the AK family of assault rifles . The acronym GP stands for Granatomyot Podstvolnyj , "under-barrel grenade launcher" in Russian, and was adopted by Soviet forces in 1978. The development of a grenade launcher for the AKM assault rifle began in 1966 at

112-410: A steel frizzen producing sparks to ignite a pan of priming powder and thereby fire the gun's main powder charge. The flintlock mechanism replaced older ignition systems such as the matchlock and wheellock , but all were prone to misfire in wet weather. The discovery of fulminates was made by Edward Charles Howard (1774–1816) in 1800. The invention that made the percussion cap possible using

168-488: A Manton patch-lock, which could be troublesome, by designing a cap and nipple arrangement around 1816 when the patch lock was patented. He says he then presented a drawing to a reluctant Joseph Manton to make a few copper cap guns which were then sold. Hawker, seems to give Joseph Manton more of the glory eight years later in the 1838 edition of his 'Instructions to young Sportsmen', by stating categorically that "copper tubes and primers were decidedly invented by Joe Manton". By

224-461: A Short Range World Championship in even-numbered years and a Long Range World Championship (300–1,000 yd (270–910 m)) on odd numbered years (South Africa has won the last 5 Long Range World Championships). Driven by demand for muzzleloaders for special extended primitive hunting seasons, firearms manufacturers have developed in-line muzzleloading rifles with designs similar to modern breech-loading centerfire designs. Knight Rifles pioneered

280-405: A ball which is slightly smaller than the barrel diameter. In other types of round ball firing rifles, a ramrod and hammer is used to force the round ball down through the rifling. When fired, either the lead ball or the wrapping grips the rifling and imparts spin to the ball which usually gives improved accuracy. In rifles firing Minié balls , the patch, often the paper wrapping from the cartridge,

336-422: A closed breech, sealed primer and fast rifling to allow for considerable accuracy at long ranges. Modern mortars use a shell with the propelling charge and primer attached at the base. Unlike older muzzleloading mortars, which were loaded the same way as muzzleloading cannon, the modern mortar is fired by dropping the shell down the barrel where a pin fires the primer, igniting the main propelling charge. Both

392-486: A copper cup filled with fulminates. The first purpose-built caplock guns were fowling pieces commissioned by sportsmen in Regency era England. Due to the mechanism's compactness and superior reliability compared to the flintlock, gunsmiths were able to manufacture pistols and long guns with two barrels . Early caplock handguns with two or more barrels and a single lock are known as turn-over or twister pistols , due to

448-404: A jammed tape primer system would instead reduce the rifle to an awkward club. This invention was gradually improved, and came to be used, first in a steel cap and then in a copper cap, by various gunmakers and private individuals before coming into general military use nearly thirty years later. The alteration of the military flintlock to the percussion musket was easily accomplished by replacing

504-436: A loose propellant (i.e., gunpowder ) and projectile, as well as a separate method of ignition or priming. In general, the sequence of loading is to put in first gunpowder, by pouring in a measured amount of loose powder, historically mostly by using a powder flask (or powder horn), or by inserting a pre-measured bag or paper packet of gunpowder (called a cartridge ) or by inserting solid propellant pellets. The gunpowder used

560-401: A nearly identical fashion to flintlock firearms and used a fulminating primer made of fulminate of mercury, chlorate of potash , sulphur and charcoal , ignited by concussion. His invention of a fulminate-primed firing mechanism deprived the birds of their early warning system, both by avoiding the initial puff of smoke from the flintlock powder pan, as well as shortening the interval between

616-469: A paper cartridge filled with black powder and strike the percussion cap that was fastened to the base of the bullet. While it had a number of problems, it was widely used by the Prussians and other German states in the mid-nineteenth century and was a major factor in the 1866 Austro-Prussian War . The needle gun originally fired paper cartridges containing a bullet, powder charge and percussion cap, but by

672-412: A priming charge was placed in the priming pan or a percussion cap was placed on the nipple, the firing mechanism initiated; the cock or hammer was then cocked to make the firearm ready to fire. Muzzleloading firearms generally use round balls, cylindrical conical projectiles, and shot charges. In some types of rifles firing round ball, a lubricated patch (see Kentucky rifle ) of fabric is wrapped around

728-500: A supply of tiny fulminate detonator discs in a small magazine. Cocking the hammer automatically advanced a disc into position. However, these automatic feed systems were difficult to make with the manufacturing systems in the early and mid-nineteenth century and generated more problems than they solved. They were quickly shelved in favor of a single percussion cap that, while unwieldy in some conditions, could be carried in sufficient quantities to make up for occasionally dropping one, while

784-541: A tremendous boost in the 1960s and 1970s. The Muzzle Loaders Associations International Committee (www.MLAIC.org) was formed in 1970 and held its first World Championship in 1971. Since then a flourishing industry manufacturing working reproductions of historic firearms now exists in the United States and Europe , particularly in northern Italy , for example at Gardone Val Trompia , in the Province of Brescia . In

840-445: Is a percussion gun . Any long gun with a cap-lock mechanism and rifled barrel is a percussion rifle . Cap and ball describes cap-lock firearms discharging a single bore-diameter spherical bullet with each shot. The percussion cap is a small cylinder of copper or brass with one closed end. Inside the closed end is a small amount of a shock-sensitive explosive material such as mercuric fulminate (discovered in 1800; it

896-417: Is made from felt, paper, cloth or card and has several different uses. In shotguns , a card wad or other secure wadding is used between the powder and the shot charge to prevent pellets from dropping into the powder charge and on top of the shot charge to hold it in place in the barrel. In smooth bore muskets and most rifles used prior to cartridges being introduced in the mid-to late nineteenth century, wadding

952-458: Is no residue left in the barrel to reduce accuracy, though in competitions run by the international governing body, the MLAIC, this is prohibited for military rifle and musket events. However, in small arms muzzleloading rifles, swabbing is only done after every 5-10 shots. Large caliber muzzle-loaders such as cannons are always swabbed between shots to prevent accidents caused by live sparks igniting

1008-480: Is typically black powder or black powder substitutes like Pyrodex . Sometimes two types of gunpowder (and two flasks) were used consisting of finer priming powder for the flash pan and coarser powder for the main charge behind the ball. This was particularly the case with earlier muzzleloaders like matchlocks but appear to have been less common with flintlocks and was irrelevant with percussion locks since they used percussion caps rather than priming powder. Wadding

1064-534: Is used as an initial seal and to hold powder in place during loading. The Minié ball replaced the round ball in most firearms, especially for military use, in the 1840s and 1850s . It has a hollow base which expands to grip the rifling. The combination of the spinning Minié ball and the consistent velocity provided by the improved seal gave far better accuracy than the smoothbore muzzleloaders that it replaced. When aiming for great accuracy, muzzle-loaders are usually cleaned ("swabbed") before reloading, so that there

1120-552: The 1853 Enfield and 1861 Springfield , this involved installing a firing pin in place of the nipple, and a trapdoor in the breech to accept the new bullets. Examples include the Trapdoor Springfield , Tabatière rifle , Westley Richards and Snider–Enfield conversions. The British Army used Snider Enfields contemporaneously with the Martini–Henry rifle until the .303 bolt action Lee–Metford repeating rifle

1176-507: The AK-100 series of assault rifles. The GP-30M is a grenade launcher of simplified model, consisting of a shorter 40mm rifled barrel in front of a basic trigger mechanism with minimal hand grip. The current Izhmash -made version, the GP-34 , has a further-redesigned sighting system located to the right side of the weapon and features the following advantages: A grenade is first loaded from

1232-1144: The US Cavalry during the Indian Wars , and also by gunfighters , lawmen, and outlaws in the old west. In the 1840s and 1850s, the percussion cap was first integrated into a metallic cartridge, where the bullet is held in by the casing, the casing is filled with gunpowder, and a primer is placed on the end. By the 1860s and 1870s, breech-loading metallic cartridges had made the percussion cap system obsolete. Today, reproduction percussion firearms are popular for recreational shooters and percussion caps are still available (though some modern muzzleloaders use shotshell primers instead of caps). Most percussion caps now use non-corrosive compounds such as lead styphnate . Caps are used in cartridges , grenades , rocket-propelled grenades and rescue flares . Percussion caps are also used in land mine fuzes , booby-trap firing devices and anti-handling devices . Most purpose-made military booby-trap firing devices contain some form of spring-loaded firing pin designed to strike

1288-440: The 1850s Hawker was again claiming the invention for himself in his press advertisements. Despite many years of research by Winant, Gooding and De Witt Bailey, the jury is still out as the competing claims are based on personal accounts and have little or no independently verifiable evidence. While the metal percussion cap was the most popular and widely used type of primer, their small size made them difficult to handle under

1344-472: The 1850s onwards, and new guns based on existing designs were manufactured as caplocks. The Austrians instead used a variant of Manton's tube lock in their Augustin musket until the conventional caplock Lorenz rifle was introduced in 1855. The first practical solution for the problem of handling percussion caps in battle was the Prussian 1841 ( Dreyse needle gun ), which used a long needle to penetrate

1400-638: The Central Design and Research Bureau of Sporting and Hunting Arms ( TsKIB SOO ). Development continued into the 1970s, and in 1978 it was accepted into service. The initial version was designated the BG-15 Mukha ("Fly"), and was mounted under the barrel of the AK-74 assault rifle. The main production version, the GP-25 , has a different aiming system. The GP-30 was made lighter and the aiming system

1456-569: The US military was the percussion carbine version (c.1833) of the M1819 Hall rifle . The Americans' breech loading caplock Hall rifles, muzzle loading rifled muskets and Colt Dragoon revolvers gave them an advantage over the smoothbore flintlock Brown Bess muskets used by Santa Anna 's troops during the Mexican War . In Japan, matchlock pistols and muskets were converted to percussion from

1512-827: The United States muzzleloading guns are, subject to a number of qualifications, generally not considered firearms. Subject to state law they may be possessed by persons who might otherwise not be legally allowed to own a firearm. The American National Muzzle Loading Rifle Association holds two national tournaments a year in Friendship, Indiana as well as the Western National Shoot Event held in Phoenix, Arizona. The Muzzle Loaders Associations International Committee (MLAIC) governs international competition with muzzle-loading arms. The MLAIC holds

1568-665: The base of the grenade – provides for when the grenade is fired nothing is left in the barrel, so the operator can load the next grenade. A bouncing grenade, the VOG-25P, is also available. On impact, a small charge in the nose of the grenade explodes; this raises the grenade 50cm to 1.5m in the air, before an impact delay fuse causes it to detonate. The VOG-25P also has a lethal radius of six meters. The new generation VOG-M and VOG-PM ammunition, with an increased effectiveness of no less than 1.5 times, are now serially available. Smoke grenades are also available. The original GRD-40 grenade

1624-404: The early 1820s, is a type of single-use percussion ignition device for muzzle loader firearm locks enabling them to fire reliably in any weather condition. Its invention gave rise to the caplock mechanism or percussion lock system which used percussion caps struck by the hammer to set off the gunpowder charge in rifles and cap and ball firearms . Any firearm using a caplock mechanism

1680-418: The flintlock. Many of the older flintlock weapons were later converted to the caplock, so that they could take advantage of these features. Joshua Shaw is sometimes credited (primarily by himself) with the development of the first metallic percussion cap in 1814, a reusable one made of iron, then a disposable pewter one in 1815 and finally a copper one in 1816. There is no independent proof of this since Shaw

1736-597: The fragments of the cap if it fragmented, reducing the risk of injury to the firer's eyes. From the 1820s onwards, the armies of Britain, France, Russia, and America began converting their muskets to the new percussion system. Caplocks were generally applied to the British military musket (the Brown Bess ) in 1842, a quarter of a century after the invention of percussion powder and after an elaborate government test at Woolwich in 1834. The first percussion firearm produced for

1792-418: The fresh charge of powder as it is being loaded. Muzzleloading is the sport or pastime of firing muzzleloading guns. Muzzleloading guns, both antique and reproduction, are used for target shooting, hunting, historical re-enactment and historical research. The sport originated in the United States in the 1930s, just as the last original users and makers of muzzleloading arms were dying out. The sport received

1848-582: The idea in Britain. The earliest known patent anywhere in the world which specifically mentions a percussion cap and nipple was granted in France on 29 July 1818 to François Prélat , four years before Shaw's patent. Prelat made a habit of copying English patents and inventions and the mode of operation he describes is flawed. Secondly a French patent of a percussion cap and nipple had been granted in 1820 to Deboubert. However predating both of these French claims,

1904-450: The idea until 1822, having moved to America in 1817. According to Lewis Winant, the US government's decision to award Shaw $ 25,000 as compensation for his invention being used by the Army was a mistake. Congress believed Shaw's patent was the earliest in the world and awarded him a large sum of money based on this belief. The investigators had overlooked two French patents and the earlier use of

1960-601: The in-line muzzleloader in the mid-1980s, manufacturing and selling them to this day. Savage Arms has created the 10ML-II, which can be used with smokeless powder, reducing the cleaning required. However, Savage has discontinued the production of smokeless muzzleloaders. Remington Firearms also have a muzzleloader in production, the model "700 Ultimate" or "700 SL Ultimate". There are several custom gun makers that are currently building smokeless muzzleloaders on new or donor bolt actions. Percussion cap The percussion cap , percussion primer , or caplock , introduced in

2016-399: The modern mortar and the older mortar were used for high angle fire. However, the fact that the mortar is not loaded in separate steps may make its definition as a muzzleloader a matter of opinion. Muzzleloading can apply to anything from cannons to pistols but in modern parlance the term most commonly applies to black powder small arms . It usually, but not always, involves the use of

2072-409: The most likely inventor of the percussion cap, according to historian Sidney James Gooding, was Joseph Egg (nephew of Durs Egg ), around 1817, . There were other earlier claims. Col. Peter Hawker in 1830 simultaneously claimed and denied being the inventor. "I do not wish to say I was the inventor of it - very probably not" but then immediately recounts that he came up with the idea of simplifying

2128-405: The muzzle, the weapon is aimed, and then the double-action trigger is pulled to fire. This fires the percussion cap at the base of the grenade which activates the nitrocellulose propellant inside the grenade body. The hot, expanding gas from the propellant is forced through openings in the base of the grenade that move it along the barrel and, at the same time, force the driving band to fit into

2184-432: The need to manually rotate the second barrel to align with the hammer. With the addition of a third barrel, and a ratchet to mechanically turn the barrels while cocking the hammer, these caplock pistols evolved into the pepper-box revolver during the 1830s. The caplock offered many improvements over the flintlock. The caplock was easier and quicker to load, more resilient to weather conditions, and far more reliable than

2240-421: The percussion cap against the nipple (which serves as an anvil ), crushes it and detonates the mercury fulminate inside, which releases sparks that travel through the hollow nipple into the barrel and ignite the main powder charge. Percussion caps have been made in small sizes for pistols and larger sizes for rifles and muskets. Earlier firearms used flintlock mechanisms causing a piece of flint to strike

2296-412: The powder pan and steel frizzen with a nipple and by replacing the cock or hammer that held the flint by a smaller hammer formed with a hollow made to fit around the nipple when released by the trigger. On the nipple was placed the copper cap containing Shaw's detonating composition of three parts of chlorate of potash, two of fulminate of mercury and one of powdered glass. The hollow in the hammer contained

2352-401: The propellant charge. Priming powder could be carried in a separate priming flask and poured into the priming pan or a little powder from the cartridge was used, and the frizzen was pushed down to hold the priming powder in place. After the gunpowder and projectile or shot charge were placed in the barrel a ramrod was used to firmly pack everything down at the base of the barrel. Then either

2408-501: The recently discovered fulminates was patented by the Reverend Alexander John Forsyth of Belhelvie , Aberdeenshire, Scotland, in 1807. The rudimentary percussion system was invented by Forsyth as a solution to the problem that birds would startle when smoke puffed from the powder pan of his flintlock shotgun, giving them sufficient warning to escape the shot. This early percussion lock system operated in

2464-477: The stress of combat or while riding a horse. Accordingly, several manufacturers developed alternative, "auto-priming" systems. The " Maynard tape primer ", for example, used a roll of paper "caps" much like today's toy cap gun . The Maynard tape primer was fitted to some firearms used in the mid-nineteenth century and a few saw brief use in the American Civil War . Other disc or pellet-type primers held

2520-402: The time muzzleloaders were in use, a round ball and pre-measured powder charge could be carried in a paper or cloth wrapping. The shooter would bite off the end of the paper cartridge with his teeth and pour the powder into the barrel followed by the ball encased in the paper wrapping. The projectiles and wads were then pushed down into the breech with a ramrod until they were firmly seated on

2576-599: The time of the Franco-Prussian War this had evolved into modern brass ammunition. The percussion cap brought about the invention of the modern cartridge case and made possible the general adoption of the breech-loading principle for all varieties of rifles, shotguns and pistols. After the American Civil War, Britain, France, and America began converting existing caplock guns to accept brass rimfire and centrefire cartridges. For muskets such as

2632-512: The trigger pull and the shot leaving the muzzle. Forsyth patented his "scent bottle" ignition system in 1807. However, it was not until after Forsyth's patents expired that the conventional percussion cap system was developed. Joseph Manton invented a precursor to the percussion cap in 1814, comprising a copper tube that detonated when crushed. This was further developed in 1822 by the English-born American artist Joshua Shaw , as

2688-406: The twelve grooves of the rifle. The rifling provides stabilizing rotation to the projectile. The grenade has a range of up to 400m. GP grenade launchers fire multiple 40mm VOG-25 high-explosive fragmentation grenades, with a total range of 400 meters and an effective range of 150m. These Russian-Soviet 40 mm grenades are not compatible with Western 40x46mm grenades. Originally, the main grenade

2744-410: Was advised he could not patent it due to Alexander Forsyth's patent for using fulminates to ignite guns being in force between 1807 and 1821. Shaw says he only shared the development of his innovation with a few associates (gunmakers and others) who were sworn to secrecy and never provided affidavits at a later date. Shaw's claim to have been the inventor remains clouded in controversy as he did not patent

2800-597: Was introduced in the 1880s. Later, military surplus Sniders were purchased as hunting and defensive weapons by British colonists and trusted local natives. Caplock revolvers such as the Colt Navy and Remington were also widely converted during the late 19th century, by replacing the existing cylinder with one designed for modern ammunition. These were used extensively by the Turks in the Russo-Turkish War ,

2856-452: Was known from very early on, but until roughly around 1800 loading using a powder flask and a bag of balls was more common outside of the military. The measuring stage for the barrel charge of gunpowder could be avoided by carrying a number of pre-measured charges in small containers of wood, metal or cloth, often carried on a bandolier . These were known by various names, including "chargers" or "apostles" as 12 were often carried. For most of

2912-405: Was redesigned and moved to the right. GP grenade launchers are similar in appearance and fire the same Russian 40mm caliber ammunition. At the top of the barrel is the mounting hardware to attach the weapon to the underside of a rifle barrel, from which it is designed to fire. The GP barrel has a useful life of about 400 rounds. The GP-30 first entered service in 1989, and is intended for use with

2968-631: Was replaced by a series of grenades designed for use at different ranges. These are the GRD-50, GRD-100 and GRD-200 intended for use at 50, 100 and 200 meters respectively. They are capable of producing a 20 cubic meter cloud of smoke that lasts for one minute in winds of up to five meters per second. A tear gas grenade called Gvozd ("Nail") and a stick grenade are also available. Muzzleloader Modern muzzleloading firearms range from reproductions of sidelock, flintlock and percussion long guns, to in-line rifles that use modern inventions such as

3024-539: Was the VOG-15 (7P17) fragmentation grenade, which has a lethal radius of six meters. Ammunition for the muzzle-loading GP-25 consists of a single piece containing propellant and charge, as opposed to the more traditional two-piece case and projectile design of comparable US 40x46mm ammunition used in breech-loading grenade launchers, such as the M203 . This integral "caseless" design – with the propellant and primer contained in

3080-399: Was the only practical detonator used from about the mid-19th century to the early 20th century ). The caplock mechanism consists of a hammer and a nipple (sometimes referred to as a cone ). The nipple contains a hollow conduit which goes into the rearmost part of the gun barrel, and the percussion cap is placed over the nipple hole. Pulling the trigger releases the hammer, which strikes

3136-404: Was used primarily to hold the powder in place. On most naval cannons, one piece of wadding was used to hold the powder in place and served the purpose of creating a better seal around the shot. Another was used to act as a plug to stop the shot rolling out because of the swaying of the ship. The use of cartridges with both gunpowder charge and ball, made up in batches by the shooter or a servant,
