Eduard Rubin
Eduard Alexander Rubin (17 July 1846 – 6 July 1920) was a Swiss mechanical engineer who is most notable for having invented the full metal jacket bullet in 1882. His most famous cartridge was the 7.5×55mm Swiss which was the standard ammunition for the Schmidt–Rubin, K31 and Stgw 57 military rifles. Besides the full metal jacket bullet, Rubin developed the military Schmidt-Rubin rifle (together with Rudolf Schmidt), the Rubin-Fornerod ignition mechanism and the use of TNT and ammonium nitrate to replace gunpowder in artillery grenades. His fully copper clad bullets were also the inspiration for the full metal jacket bullets introduced in 1886 for the Lebel rifle. He served as director of the Swiss Federal Ammunition Factory and Research Center in Thun. He held the rank of colonel in the Swiss military The Swiss Armed Forces (german: Schweizer Armee, french: Armée suisse, it, Esercito svizzero, rm, Armada svizra; ) operates on land and in the air, serving as ...

Full Metal Jacket Bullet
A full metal jacket (FMJ) bullet is a small-arms projectile consisting of a soft core (often lead) encased in an outer shell ("jacket") of harder metal, such as gilding metal, cupronickel, or, less commonly, a steel alloy. A bullet jacket usually allows higher muzzle velocities than bare lead without depositing significant amounts of metal in the bore. It also prevents damage to bores from hard steel or armor-piercing core materials. History The bullet was invented in 1882 by Swiss Colonel Eduard Rubin while he was working for the Swiss Federal Ammunition Factory and Research Center, which developed ammunition for the Swiss military. The use of full metal jacketing in military ammunition came about in part because of the need for improved feeding characteristics in small arms that used internal mechanical manipulation of the cartridge in order to chamber rounds as opposed to externally hand-reloading single-shot firearms. The harder metal used in bullet jackets was less pr ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Schmidt–Rubin
The Schmidt–Rubin rifles were a series of Swiss Army service rifles in use between 1889 and 1958. They are distinguished by the straight-pull bolt action invented by Rudolf Schmidt and use Eduard Rubin's 7.5×55mm Schmidt–Rubin rifle cartridge. Models Schmidt–Rubin 1889 The Model 1889 was the first in the series of Schmidt–Rubin rifles which served Switzerland from 1889 to 1953. The rifle takes its name from the designer of its action, Colonel Rudolf Schmidt, and the designer of its ammunition, Colonel Eduard Rubin. Production of the rifle began in 1891. The straight-pull bolt action allows the user to pull the bolt straight back to unlock the action, cock the striker, extract, and eject the spent cartridge in one motion, and then push the bolt forward to chamber a round and lock the action. This is as opposed to a traditional bolt action, wherein the user must lift the bolt handle to unlock the action before pulling the bolt back. The rifle is roughly musket length wit ...

Stgw 57
The Sturmgewehr 57 is a selective fire battle rifle designed by Schweizerische Industrie Gesellschaft (now SAN Swiss Arms) of Switzerland. It uses a roller-delayed blowback system similar to the H&K G3 and CETME rifles. The AM 55 entered service in the Swiss Army with the designation F. ass. 57 7.5mm (French/Italian, for ''Fusil d'Assaut/Fucile d'Assalto 1957'') or 7.5mm Stgw. 57 (German for ''Sturmgewehr 1957''), with export variations constituting the SG 510 family of small arms. The Sturmgewehr 57 was adopted for Swiss military service in 1957 and replaced in 1990 by the lighter SIG SG 550 assault rifle, although some reservists used it for several more years. Design details The Stgw. 57 was developed during the late 1950s, internally named AM 55 at SIG. During its development, Rudolf Amsler was the principal designer at Schweizerische Industrie Gesellschaft. It is a selective fire rifle that employs a roller-delayed blowback operating system. The Stgw. 57 was used by th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ammonium Nitrate
Ammonium nitrate is a chemical compound with the chemical formula . It is a white crystalline salt consisting of ions of ammonium and nitrate. It is highly soluble in water and hygroscopic as a solid, although it does not form hydrates. It is predominantly used in agriculture as a high-nitrogen fertilizer.Karl-Heinz Zapp "Ammonium Compounds" in ''Ullmann's Encyclopedia of Industrial Chemistry'' 2012, Wiley-VCH, Weinheim. Global production was estimated at 21.6 million tonnes in 2017. Its other major use is as a component of explosive mixtures used in mining, quarrying, and civil construction. It is the major constituent of ANFO, a popular industrial explosive which accounts for 80% of explosives used in North America; similar formulations have been used in improvised explosive devices. Many countries are phasing out its use in consumer applications due to concerns over its potential for misuse.

Lebel Rifle
The Lebel Model 1886 rifle (French: ''Fusil Modèle 1886 dit "Fusil Lebel"'') also known as the ''"Fusil Mle 1886 M93"'', after a bolt modification was added in 1893, is an 8 mm bolt-action infantry rifle that entered service in the French Army in 1887. It is a repeating rifle that can hold eight rounds in its fore-stock tube magazine, one round in the elevator plus one round in the chamber; equaling a total of ten rounds held. The Lebel rifle has the distinction of being the first military firearm to use smokeless powder ammunition. The new propellant powder, "''Poudre B''," was nitrocellulose-based and had been invented in 1884 by French chemist Paul Vieille. Lieutenant Colonel Nicolas Lebel contributed a flat nosed 8 mm full metal jacket bullet ("''Balle M''," or "''Balle Lebel''"). Twelve years later, in 1898, a solid brass pointed ( spitzer) and boat-tail bullet called "''Balle D''" was retained for all 8mm Lebel ammunition. Each case was protected against acciden ...

Oberst
''Oberst'' () is a senior field officer rank in several German-speaking and Scandinavian countries, equivalent to colonel. It is currently used by both the ground and air forces of Austria, Germany, Switzerland, Denmark, and Norway. The Swedish rank '' överste'' is a direct translation, as are the Finnish rank ''eversti'' and the Icelandic rank ''ofursti''. History and origins is a German word. Spelled with a capital O, "" is a noun and defines the military rank of colonel or group captain. Spelled with a lower case o, or "", it is an adjective, meaning "top, topmost, uppermost, highest, chief, head, first, principal, or supreme". Both usages derive from the superlative of , "the upper" or "the uppermost". As a family name, ''Oberst'' is common in the southwest of Germany, in the area known as the Black Forest (''Schwarzwald''). The name is also concentrated in the north-central cantons of Switzerland ( Aargau & Zürich). Here the Swiss version of ''Oberst'' is spelled ''Ob ...

Swiss Military
The Swiss Armed Forces (german: Schweizer Armee, french: Armée suisse, it, Esercito svizzero, rm, Armada svizra; ) operates on land and in the air, serving as the primary armed forces of Switzerland. Under the country's militia system, soldier, regular soldiers constitute a small part of the military and the rest are conscripts or volunteers aged 19 to 34 (in some cases up to 50). Because of Swiss neutrality, Switzerland's long history of neutrality, the Swiss Armed Forces do not take part in conflicts in other countries, but do participate in Peacekeeping, international peacekeeping missions. Switzerland is part of the NATO Partnership for Peace programme. The regulations of the Swiss militia system stipulate that the soldiers keep their own personal equipment, including all personally assigned weapons, at home (until 2007 this also included ammunition), or in an armoury. Conscription in Switzerland, Compulsory military service applies to all male Swiss citizens, with wome ...

Swiss Cartographer
The cartography of Switzerland is the history of surveying and creation of maps of Switzerland. Switzerland has had its current boundaries since 1815, but maps of the Old Swiss Confederacy were drawn since the 16th century. The first topographical survey on a federal level began in 1809, resulting in the Topographic Map of Switzerland (German: ''Topographische Karte der Schweiz'') or ''Dufour Map'' (German: ''Dufourkarte''; French: ''Carte Dufour''). From 1869 to 1901, this map was replaced by the Topographic Atlas of Switzerland (German: ''Topographischer Atlas der Schweiz'') or ''Siegfried Map'' (German: ''Siegfriedkarte''; French: ''Carte Siegfried''). From 1901, the ''Topographical Survey of Switzerland'' is an independent division within the military, introducing the Swiss coordinate system in 1903. The office is renamed as the Swiss Federal Office of Topography in 1979, with thswisstopo.chwebsite online since 1997. Old Swiss Confederacy The first systematic geographical d ...
