Shiloh Rifle Manufacturing Company is a firearms manufacturer located in Big Timber, Montana , United States .
91-593: The company produces a line of reproductions of various historical black-powder rifles, including the legendary 1874 Sharps Rifle , featured in the 1990 Western film Quigley Down Under , starring Tom Selleck . Shiloh Sharps Rifle began production in 1983. Previously, the Sharps rifle reproductions were manufactured by Shiloh Products Inc. founded by Len Mulé (pronounce Mull-A) of Garfield, New Jersey , in partnership with Wolfgang Droge, who owned Drovel Tool Company of Farmingdale, New York , from 1976 to 1983. Len Mulé
182-659: A "long lance" sending forth "evil-smelling vapors and smoke", which has been variously interpreted by different historians as the "first-gas attack upon European soil" using gunpowder, "the first use of cannon in Europe", or merely a "toxic gas" with no evidence of gunpowder. It is difficult to accurately translate original Chinese alchemical texts, which tend to explain phenomena through metaphor, into modern scientific language with rigidly defined terminology in English. Early texts potentially mentioning gunpowder are sometimes marked by

Shah Jahan also countered the British and other Europeans in his province of Gujarāt , which supplied Europe saltpeter for use in gunpowder warfare during the 17th century. Bengal and Mālwa participated in saltpeter production. The Dutch, French, Portuguese, and English used Chhapra as a center of saltpeter refining. Ever since the founding of
364-499: A deflagration or a detonation can be difficult to impossible to the casual observer. Rather, confidently differentiating between the two requires instrumentation and diagnostics to ascertain reaction speed in the affected material. Therefore, when an unexpected event or an accident occurs with an explosive material or an explosive-containing system it is usually impossible to know whether the explosive deflagrated or detonated as both can appear as very violent, energetic reactions. Therefore,
455-473: A formula with near-identical ideal composition ratios for explosive gunpowder. Other historians urge caution regarding claims of Islamic firearms use in the 1204–1324 period, as late medieval Arabic texts used the same word for gunpowder, naft , that they used for an earlier incendiary, naphtha. The earliest surviving documentary evidence for cannons in the Islamic world is from an Arabic manuscript dated to
546-436: A gunpowder composition containing pure carbon would burn similarly to a match head, at best. The current standard composition for the gunpowder manufactured by pyrotechnicians was adopted as long ago as 1780. Proportions by weight are 75% potassium nitrate (known as saltpeter or saltpetre), 15% softwood charcoal, and 10% sulfur. These ratios have varied over the centuries and by country, and can be altered somewhat depending on
637-742: A linguistic process where semantic change occurred. For instance, the Arabic word naft transitioned from denoting naphtha to denoting gunpowder, and the Chinese word pào changed in meaning from trebuchet to a cannon . This has led to arguments on the exact origins of gunpowder based on etymological foundations. Science and technology historian Bert S. Hall makes the observation that, "It goes without saying, however, that historians bent on special pleading, or simply with axes of their own to grind, can find rich material in these terminological thickets." Another major area of contention in modern studies of
728-523: A medicine to an incendiary and explosive, and the evolution of the gun from the fire lance to a metal gun, whereas similar records do not exist elsewhere. As Andrade explains, the large amount of variation in gunpowder recipes in China relative to Europe is "evidence of experimentation in China, where gunpowder was at first used as an incendiary and only later became an explosive and a propellant... in contrast, formulas in Europe diverged only very slightly from
819-422: A mixture of sulfur , charcoal (which is mostly carbon ), and potassium nitrate (saltpeter) . The sulfur and charcoal act as fuels while the saltpeter is an oxidizer . Gunpowder has been widely used as a propellant in firearms , artillery , rocketry , and pyrotechnics , including use as a blasting agent for explosives in quarrying , mining , building pipelines , tunnels , and roads . Gunpowder
910-838: A regular basis outside of China." May also states, "however [, ...] the Mongols used the gunpowder weapon in their wars against the Jin, the Song and in their invasions of Japan." Records show that, in England, gunpowder was being made in 1346 at the Tower of London ; a powder house existed at the Tower in 1461, and in 1515 three King's gunpowder makers worked there. Gunpowder was also being made or stored at other royal castles, such as Portchester . The English Civil War (1642–1645) led to an expansion of
1001-512: A ruler and tried to ward off any Mongol attempt similar to the Siege of Baghdad (1258) . Firearms known as top-o-tufak also existed in many Muslim kingdoms in India by as early as 1366. From then on the employment of gunpowder warfare in India was prevalent, with events such as the "Siege of Belgaum " in 1473 by Sultan Muhammad Shah Bahmani.

However, because of its low brisance , gunpowder causes fewer fractures and results in more usable stone compared to other explosives, making it useful for blasting slate , which is fragile, or monumental stone such as granite and marble . Gunpowder
1183-559: A shipwreck off the shore of Japan dated from 1281, during the Mongol invasions of Japan. By 1083 the Song court was producing hundreds of thousands of fire arrows for their garrisons. Bombs and the first proto-guns, known as "fire lances", became prominent during the 12th century and were used by the Song during the Jin-Song Wars . Fire lances were first recorded to have been used at the Siege of De'an in 1132 by Song forces against

Some of it ends up as a thick layer of soot inside the barrel, where it also is a nuisance for subsequent shots, and a cause of jamming an automatic weapon. Moreover, this residue is hygroscopic , and with the addition of moisture absorbed from the air forms a corrosive substance . The soot contains potassium oxide or sodium oxide that turns into potassium hydroxide , or sodium hydroxide , which corrodes wrought iron or steel gun barrels. Gunpowder arms therefore require thorough and regular cleaning to remove
1365-408: A stock. Some consider this to be a cannon while others do not. The problem with identifying cannons in early 14th century Arabic texts is the term midfa , which appears from 1342 to 1352 but cannot be proven to be true hand-guns or bombards. Contemporary accounts of a metal-barrel cannon in the Islamic world do not occur until 1365. Needham believes that in its original form the term midfa refers to
1456-493: A thin transitional region of width δ {\displaystyle \delta \;} in which the burning occurs. The burning region is commonly referred to as the flame or flame front . In equilibrium, thermal diffusion across the flame front is balanced by the heat supplied by burning. Two characteristic timescales are important here. The first is the thermal diffusion timescale τ d {\displaystyle \tau _{d}\;} , which

The Muslims acquired knowledge of gunpowder sometime between 1240 and 1280, by which point the Syrian Hasan al-Rammah had written recipes, instructions for the purification of saltpeter, and descriptions of gunpowder incendiaries. It
1638-481: Is subsonic combustion in which a pre-mixed flame propagates through an explosive or a mixture of fuel and oxidizer. Deflagrations in high and low explosives or fuel–oxidizer mixtures may transition to a detonation depending upon confinement and other factors. Most fires found in daily life are diffusion flames . Deflagrations with flame speeds in the range of 1 m/s differ from detonations which propagate supersonically with detonation velocities in
1729-430: Is an advantage in a propellant device, where one does not desire a shock that would shatter the gun and potentially harm the operator; however, it is a drawback when an explosion is desired. In that case, the propellant (and most importantly, gases produced by its burning) must be confined. Since it contains its own oxidizer and additionally burns faster under pressure, its combustion is capable of bursting containers such as

Prismatic Brown Powder is a large-grained product the Rottweil Company introduced in 1884 in Germany, which was adopted by the British Royal Navy shortly thereafter. The French navy adopted a fine, 3.1 millimeter, not prismatic grained product called Slow Burning Cocoa (SBC) or "cocoa powder". These brown powders reduced burning rate even further by using as little as 2 percent sulfur and using charcoal made from rye straw that had not been completely charred, hence

Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate , producing a supersonic shockwave . Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from

After that, a diverse variety of firearms, large guns in particular, became visible in Tanjore , Dacca , Bijapur , and Murshidabad . Guns made of bronze were recovered from Calicut (1504)- the former capital of the Zamorins The Mughal emperor Akbar mass-produced matchlocks for
2275-553: Is one of the Four Great Inventions of China. Originally developed by Taoists for medicinal purposes, it was first used for warfare around AD 904. Its use in weapons has declined due to smokeless powder replacing it, whilst its relative inefficiency led to newer alternatives such as dynamite and ammonium nitrate/fuel oil replacing it in industrial applications. Gunpowder is a low explosive : it does not detonate , but rather deflagrates (burns quickly). This

It is also used in fireworks for lifting shells, in rockets as fuel, and in certain special effects . Combustion converts less than half the mass of gunpowder to gas; most of it turns into particulate matter. Some of it is ejected, wasting propelling power, fouling the air, and generally being a nuisance (giving away

Nasiruddin Mahmud tried to express his strength as
2821-473: The Jin . In the early 13th century the Jin used iron-casing bombs. Projectiles were added to fire lances, and re-usable fire lance barrels were developed, first out of hardened paper, and then metal. By 1257 some fire lances were firing wads of bullets. In the late 13th century metal fire lances became 'eruptors', proto-cannons firing co-viative projectiles (mixed with the propellant, rather than seated over it with

The bulkier black powder fouling better disperses primer residue. Failure to mitigate primer corrosion by dispersion caused the false impression that nitrocellulose-based powder caused corrosion. Lesmok had some of the bulk of black powder for dispersing primer residue, but somewhat less total bulk than straight black powder, thus requiring less frequent bore cleaning. It

Coarser grains were numbered as sulfur-free gunpowder (SFG n): 'SFG 12', 'SFG 20', 'SFG 40' and 'SFG 90', for example where the number represents the smallest BSS sieve mesh size, which retained no grains. Sulfur's main role in gunpowder is to decrease the ignition temperature. A sample reaction for sulfur-free gunpowder would be: The term black powder

Also if the quality of the saltpeter was low (for instance if it was contaminated with highly hygroscopic calcium nitrate ), or if the powder was simply old (due to the mildly hygroscopic nature of potassium nitrate), in humid weather it would need to be re-dried. The dust from "repairing" powder in the field was a major hazard. Deflagration Deflagration (Lat: de + flagrare , 'to burn down')

On the origins of gunpowder technology, historian Tonio Andrade remarked, "Scholars today overwhelmingly concur that the gun was invented in China." Gunpowder and the gun are widely believed by historians to have originated from China due to the large body of evidence that documents the evolution of gunpowder from

For instance, power grades of black powder, unsuitable for use in firearms but adequate for blasting rock in quarrying operations, are called blasting powder rather than gunpowder with standard proportions of 70% nitrate, 14% charcoal, and 16% sulfur; blasting powder may be made with the cheaper sodium nitrate substituted for potassium nitrate and proportions may be as low as 40% nitrate, 30% charcoal, and 30% sulfur. In 1857, Lammot du Pont solved

6825-519: The time. The state-controlled manufacture of gunpowder by the Ottoman Empire through early supply chains to obtain nitre, sulfur and high-quality charcoal from oaks in Anatolia contributed significantly to its expansion between the 15th and 18th century. It was not until later in the 19th century when the syndicalist production of Turkish gunpowder was greatly reduced, which coincided with
6916-463: The tube or cylinder of a naphtha projector ( flamethrower ), then after the invention of gunpowder it meant the tube of fire lances, and eventually it applied to the cylinder of hand-guns and cannons. According to Paul E. J. Hammer, the Mamluks certainly used cannons by 1342. According to J. Lavin, cannons were used by Moors at the siege of Algeciras in 1343. A metal cannon firing an iron ball
7007-446: The twelfth century or the beginning of the thirteenth". In Persia saltpeter was known as "Chinese salt" ( Persian : نمک چینی ) namak-i chīnī ) or "salt from Chinese salt marshes" ( نمک شوره چینی namak-i shūra-yi chīnī ). Hasan al-Rammah included 107 gunpowder recipes in his text al-Furusiyyah wa al-Manasib al-Harbiyya ( The Book of Military Horsemanship and Ingenious War Devices ), 22 of which are for rockets. If one takes
7098-470: The two individual technologies. French war powder in 1879 used the ratio 75% saltpeter, 12.5% charcoal, 12.5% sulfur. English war powder in 1879 used the ratio 75% saltpeter, 15% charcoal, 10% sulfur. The British Congreve rockets used 62.4% saltpeter, 23.2% charcoal and 14.4% sulfur, but the British Mark VII gunpowder was changed to 65% saltpeter, 20% charcoal and 15% sulfur. The explanation for
7189-528: The wars against the Tanguts in the 11th century, and China was otherwise mostly at peace during this century. However, it had already been used for fire arrows since at least the 10th century. Its first recorded military application dates its use to 904 in the form of incendiary projectiles. In the following centuries various gunpowder weapons such as bombs , fire lances , and the gun appeared in China. Explosive weapons such as bombs have been discovered in
7280-408: The whole house where they were working burned down." Based on these Taoist texts, the invention of gunpowder by Chinese alchemists was likely an accidental byproduct from experiments seeking to create the elixir of life . This experimental medicine origin is reflected in its Chinese name huoyao ( Chinese : 火药/火藥 ; pinyin : huǒ yào /xuo yɑʊ/ ), which means "fire medicine". Saltpeter
7371-517: The wide variety in formulation relates to usage. Powder used for rocketry can use a slower burn rate since it accelerates the projectile for a much longer time—whereas powders for weapons such as flintlocks, cap-locks, or matchlocks need a higher burn rate to accelerate the projectile in a much shorter distance. Cannons usually used lower burn-rate powders, because most would burst with higher burn-rate powders. Besides black powder, there are other historically important types of gunpowder. "Brown gunpowder"
7462-529: Was already an accepted technique in 1839, and sodium nitrate-based blasting powder had been made in Peru for many years using the sodium nitrate mined at Tarapacá (now in Chile). Also, in 1846, two plants were built in south-west England to make blasting powder using this sodium nitrate. The idea may well have been brought from Peru by Cornish miners returning home after completing their contracts. Another suggestion
7553-654: Was coined in the late 19th century, primarily in the United States, to distinguish prior gunpowder formulations from the new smokeless powders and semi-smokeless powders. Semi-smokeless powders featured bulk volume properties that approximated black powder, but had significantly reduced amounts of smoke and combustion products. Smokeless powder has different burning properties (pressure vs. time) and can generate higher pressures and work per gram. This can rupture older weapons designed for black powder. Smokeless powders ranged in color from brownish tan to yellow to white. Most of
7644-606: Was described by Shihab al-Din Abu al-Abbas al-Qalqashandi between 1365 and 1376. The musket appeared in the Ottoman Empire by 1465. In 1598, Chinese writer Zhao Shizhen described Turkish muskets as being superior to European muskets. The Chinese military book Wu Pei Chih (1621) later described Turkish muskets that used a rack-and-pinion mechanism, which was not known to have been used in European or Chinese firearms at
7735-521: Was filled with gunpowder, metal filings, "good mixtures", two rods, and a large rocket for propulsion. Judging by the illustration, it was evidently supposed to glide across the water. Fire lances were used in battles between the Muslims and Mongols in 1299 and 1303. Al-Hassan claims that in the Battle of Ain Jalut of 1260, the Mamluks used "the first cannon in history" against the Mongols, utilizing
7826-476: Was known to the Chinese by the mid-1st century AD and was primarily produced in the provinces of Sichuan , Shanxi , and Shandong . There is strong evidence of the use of saltpeter and sulfur in various medicinal combinations. A Chinese alchemical text dated 492 noted saltpeter burnt with a purple flame, providing a practical and reliable means of distinguishing it from other inorganic salts, thus enabling alchemists to evaluate and compare purification techniques;
7917-535: Was last sold by Winchester in 1947. The development of smokeless powders, such as cordite , in the late 19th century created the need for a spark-sensitive priming charge , such as gunpowder. However, the sulfur content of traditional gunpowders caused corrosion problems with Cordite Mk I and this led to the introduction of a range of sulfur-free gunpowders, of varying grain sizes. They typically contain 70.5 parts of saltpeter and 29.5 parts of charcoal. Like black powder, they were produced in different grain sizes. In
8008-594: Was not self-sufficient in gunpowder, a Gunpowder Administration was established; to head it, the lawyer Antoine Lavoisier was appointed. Although from a bourgeois family, after his degree in law Lavoisier became wealthy from a company set up to collect taxes for the Crown; this allowed him to pursue experimental natural science as a hobby. Without access to cheap saltpeter (controlled by the British), for hundreds of years France had relied on saltpetremen with royal warrants,
8099-572: Was recorded by Dutch and German travelers as being common in even the smallest villages and was collected from the decomposition process of large dung hills specifically piled for the purpose. The Dutch punishment for possession of non-permitted gunpowder appears to have been amputation. Ownership and manufacture of gunpowder was later prohibited by the colonial Dutch occupiers. According to colonel McKenzie quoted in Sir Thomas Stamford Raffles ', The History of Java (1817),
8190-713: Was responsible for all early drawings and mechanical drawings and prototype work on the Model 1863 and deserves credit as the second founder of Sharps and its re-introduction into the modern era. Shiloh produces two basic models of rifle, the Sharps 1863 which is a percussion rifle, and the Sharps 1874, which is a black-powder cartridge rifle (BPCR). Both rifles are produced in several variants, such as single or double trigger, upgraded wood, finish, etc. Various barrel lengths and shapes (round, octagonal, half-round, etc.). Rifles chambered in "standard" factory rounds are warranted for shooting factory smokeless powder ammunition as well, such as
8281-603: Was the American Revolution . By careful testing and adjusting the proportions and grinding time, powder from mills such as at Essonne outside Paris became the best in the world by 1788, and inexpensive. Two British physicists, Andrew Noble and Frederick Abel , worked to improve the properties of gunpowder during the late 19th century. This formed the basis for the Noble-Abel gas equation for internal ballistics . The introduction of smokeless powder in
