Jarmann M1884
The Jarmann M1884 is a Norwegian bolt-action repeating rifle designed in 1878 adopted in 1884. The Jarmann's adoption, and subsequent modifications, turned the Norwegian Army from a fighting force armed with single-shot black-powder weapons into a force armed with modern repeating weapons firing smokeless ammunition. Several thousand were manufactured to equip the Norwegian Armed Forces in the 1880s, and it also saw some, though very limited, use in Sweden. The design is unique, and was the brainchild of Norwegian engineer Jacob Smith Jarmann. After the design had been phased out of the Norwegian Army, a number of the weapons were rebuilt as harpoon guns. Description The Jarmann M1884 fired a 10.15 mm black powder cartridge in an 8-round, tubular magazine in which the rounds were lined up in a tube below the barrel. It has a non-rotating bolt (the part of the action that seals the rear end of the barrel) locked by a rotating bolt handle, and reputedly a smooth action. ...

Bolt Action
Bolt-action is a type of manual firearm action that is operated by ''directly'' manipulating the bolt via a bolt handle, which is most commonly placed on the right-hand side of the weapon (as most users are right-handed). Most bolt-action firearms use a rotating bolt design, where the handle must first be rotated upward to unlock the bolt from the receiver, then pulled back to open the breech and allowing any spent cartridge case to be extracted and ejected. This also cocks the striker within the bolt (either on opening or closing of the bolt depending on the gun design) and engages it against the sear. When the bolt is returned to the forward position, a new cartridge (if available) is pushed out of the magazine and into the barrel chamber, and finally the breech is closed tight by rotating the handle down so the bolt head relocks on the receiver. Bolt-action firearms are generally repeating firearms, but some single-shot breechloaders also use bolt-action design as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breech-loading Weapon
A breechloader is a firearm in which the user loads the ammunition (cartridge or shell) via the rear (breech) end of its barrel, as opposed to a muzzleloader, which loads ammunition via the front ( muzzle). Modern firearms are generally breech-loading – except for replicas of vintage weapons. Early firearms before the mid-19th century were almost entirely muzzle-loading. Mortars and the Russian GP-25 grenade launcher are the only muzzleloaders remaining in frequent modern usage. However, referring to a weapon specifically as breech loading is mostly limited to single-shot or otherwise non-repeating firearms, such as double-barreled shotguns. Breech-loading provides the advantage of reduced reloading time, because it is far quicker to load the projectile and propellant into the chamber of a gun/cannon than to reach all the way over to the front end to load ammunition and then push them back down a long tube – especially when the projectile fits tightly and the ...

Point-blank Range
Point-blank range is any distance over which a certain firearm can hit a target without the need to compensate for bullet drop, and can be adjusted over a wide range of distances by sighting in the firearm. If the bullet leaves the barrel parallel to the sight, the bullet, like any object in flight, is pulled downwards by gravity, so for distant targets, the shooter must point the firearm above the target to compensate. But if the target is close enough, bullet drop will be negligible so the shooter can aim the gun straight at the target. If the sights are set so that the barrel has a small upward tilt, the bullet starts by rising and later drops. This results in a weapon that hits too low for very close targets, too high for intermediate targets, too low for very far targets, and point blank at two distances in between. For a .270 Winchester, as an example, the bullet first crosses the line of sight at about 23 metres (25 yards) as it is rising and has a maximum impact above th ...

Centerfire Ammunition
Two rounds of .357 Magnum, a centerfire cartridge; notice the circular primer in the center A centerfire cartridge is a firearm metallic cartridge whose primer is located at the center of the base of its casing (i.e. "case head"). Unlike rimfire cartridges, the centerfire primer is typically a separate component seated into a recessed cavity (known as the ''primer pocket'') in the case head and is replaceable by reloading. Centerfire cartridges have supplanted the rimfire variety in all but the smallest cartridge sizes. The majority of today's handguns, rifles, and shotguns use centerfire ammunition, with the exception of a few .17 caliber, .20 caliber, and .22 caliber handgun and rifle cartridges, small-bore shotgun shells (intended for pest control), and a handful of antique (and mostly obsolete) cartridges. History An early form of centerfire ammunition, without a percussion cap, was invented between 1808 and 1812 by Jean Samuel Pauly. This was also the first fully i ...

Kropatschek
A Kropatschek is any variant of a rifle designed by Alfred von Kropatschek. Kropatschek's rifles used a tubular magazine (constructed of nickel-plated steel) of his design, of the same type used in the Japanese Murata Type 22 and the German Mauser Gewehr 1871/84. While designed for black powder, the Kropatschek action proved to be strong enough to handle smokeless powder. The Kropatschek was the basis for the French Lebel M1886. Variants Austria-Hungary: * ''Gendarmerie Repetier-Karabiner M1881'': 11 mm Gendarmerie Carbine (also known as M1874/81); *''Kropatschek Torpedo Boats Gewehr M1893'': 8 mm Navy Rifle for Torpedo boat crews.

Krag–Jørgensen
The Krag–Jørgensen is a repeating bolt-action rifle designed by the Norwegians Ole Herman Johannes Krag and Erik Jørgensen in the late 19th century. It was adopted as a standard arm by Norway, Denmark, and the United States. About 300 were delivered to Boer forces of the South African Republic. A distinctive feature of the Krag–Jørgensen action is its magazine. While many other rifles of its era use an integral box magazine loaded by a charger or stripper clip, the magazine of the Krag–Jørgensen is integral with the receiver (the part of the rifle that houses the operating parts), featuring an opening on the right hand side with a hinged cover. Instead of a charger, single cartridges are inserted through the side opening, and are pushed up, around, and into the action by a spring follower. Later, similar to a charger, a claw type clip would be made for the Krag that allowed the magazine to be loaded all at once, also known as the Krag "speedloader magazine". The ...

Ole Herman Johannes Krag
Ole Herman Johannes Krag (7 April 1837 – 9 December 1916) was a Norwegian officer and firearms designer. Biography Ole H. J. Krag was born in Vågå, in Oppland county, Norway. Krag grew up in various locations where his father, Hans Peter Schnitler Krag (1794–1855), served as pastor, including Vågå, Fredrikshald (Halden) and Christiania (Oslo). Krag was a student at Hartvig Nissens skole in Oslo. He started his military career in January 1854. He became a Second Lieutenant in 1857 and a full Lieutenant in 1861. In 1866 he was ordered to Kongsberg Våpenfabrikk, the most important Norwegian weapons factory of its day. Ole H J Krag constructed his first repeating rifle in 1868, which evolved into the Krag–Petersson (aided by Axel Petersson) by 1872. This, as well as his work in the armoury, gave him a thorough understanding of what requirements the Norwegian Army had to a rifle, allowing him to create the successful Krag–Jørgensen with the help of his good frie ...

Rotating Bolt
Rotating bolt is a method of locking the breech (or rear barrel) of a firearm closed for firing. Johann Nicolaus von Dreyse developed the first rotating bolt firearm, the "Dreyse needle gun", in 1836. The Dreyse locked using the bolt handle rather than lugs on the bolt head like the Mauser M 98 or M16. The first rotating bolt rifle with two lugs on the bolt head was the Lebel Model 1886 rifle. The concept has been implemented on most firearms chambered for high powered cartridges since the 20th century. Design Ferdinand Ritter von Mannlicher, who had earlier developed a non-rotating bolt straight-pull rifle, developed the Steyr-Mannlicher M1895, a straight-pull rifle with a rotating bolt, which was issued to the Austro-Hungarian Army. Mannlicher then developed the M1893 auto rifle which had a screw delayed bolt and later the Mannlicher M1900 operated by a gas piston. This was an inspiration for later gas operated, semi-automatic and selective fire firearms (such as the M1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
