Rifled Muzzle Loader
A rifled muzzle loader in the forecastle of HMS Gannet (1878) ">HMS_Gannet_(1878).html" ;"title="forecastle of HMS Gannet (1878)">forecastle of HMS Gannet (1878) A rifled muzzle loader (RML) is a type of large artillery piece invented in the mid-19th century. In contrast to Smoothbore, smooth bore cannon which preceded it, the rifling of the gun barrel allowed much greater accuracy and penetration as the spin induced to the shell gave it directional stability. Typical guns weighed 18 tonnes with 10-inch-diameter bores, and were installed in forts and ships. This new gun and the rifled breech loader (RBL) generated a huge arms race in the late 19th century, with rapid advances in fortifications and ironclad warships. Royal Navy experience The largest rifled muzzle-loader carried on a warship was the 17.7-inch, 100-ton Elswick of the 1870s, four of which were installed in each of the Italian battleships '' Duilio'' and ''Enrico Dandolo'' (launched in 1872).

Rifled Muzzle Loader HMS Gannet
In firearms, rifling is machining helical grooves into the internal (bore) surface of a gun's barrel for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting to stabilize the projectile longitudinally by conservation of angular momentum, improving its aerodynamic stability and accuracy over smoothbore designs. Rifling is characterized by its twist rate, which indicates the distance the rifling takes to complete one full revolution, such as "1 turn in 10 inches" (1:10 inches), "1 turn in 254 mm" ("1:254 mm" or "1:25.4 cm)", or the like. Normally, an experienced shooter can infer the units of measurement from the numbers alone. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will rotate at a higher spin rate. The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it – barrels ...

Italian Ironclad Enrico Dandolo
''Enrico Dandolo'' was the second of two turret ships built for the Italian ''Regia Marina'' (Royal Navy) in the 1870s. They were fitted with the largest guns available, rifled, muzzle-loading guns, and were the largest, fastest and most powerful ships of their day.Silverstone, p. 285 ''Enrico Dandolo'' was built in La Spezia, with her keel laid in January 1873 and her hull launched in July 1878. Construction was finally completed in April 1882 when the ship, named for the 41st Doge of Venice, was commissioned into the Italian fleet. ''Enrico Dandolo'' spent much of her career in the Active Squadron of the Italian fleet, primarily occupied with training exercises. She was heavily modernized in 1895–1898, receiving a new battery of fast-firing guns in place of the old 17.72 in guns. The ship served in the Reserve Squadron after 1905, and then became a gunnery training ship. During the Italo-Turkish War of 1911–1912, ''Enrico Dandolo'' was among the few ships of th ...

James Rifle
James rifle is a generic term to describe any artillery gun rifled to the James pattern for use in the American Civil War, as used in some period documentation. Charles T. James developed a rifled projectile and rifling system. Modern authorities such as Warren Ripley and James Hazlett have suggested that the term "James rifle" only properly applies to bore field artillery pieces rifled to fire James' projectiles. They contend that the term does not apply to smoothbores that were later rifled to take the James projectiles in caliber or other calibers, and that those should instead be referred to as "Rifled 6 (or other) pounder", etc. Field artillery Early in the war there were many 6-pounder (2.72 kg) bronze smoothbore guns in service with the field artillery and few rifled pieces available. A number of these guns were rifled to fire the caliber James projectile. These are classified as "rifled 6-pounder guns" or alternately as 12-pounder (5.44 kg) James rifle ...

Brooke Rifle
The Brooke rifle was a type of rifled, muzzle-loading naval and coast defense gun designed by John Mercer Brooke, an officer in the Confederate States Navy. They were produced by plants in Richmond, Virginia, and Selma, Alabama, between 1861 and 1865 during the American Civil War. They served afloat on Confederate ships and ashore in coast defense batteries operated by the Confederate States Army. Design and production Brookes can be identified by the presence of at least one band of wrought iron at the breech and a rough-finished, tapering barrel. The barrels were made of cast iron for ease of manufacture, but one or more wrought iron bands was welded around the chamber to reinforce it against the high chamber pressure exerted when the gun fired. Because no southern foundries had the capacity to wrap the rifles in a single band like the Parrott design, a series of smaller bands were used, each usually thick and wide. All of Brooke's rifles used the same seven-groove rifling wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parrott Rifle
The Parrott rifle was a type of muzzle-loading rifled artillery weapon used extensively in the American Civil War. Parrott rifle The gun was invented by Captain Robert Parker Parrott, a West Point graduate. He was an American soldier and inventor of military ordnance. He resigned from the service in 1836 and became the superintendent of the West Point Foundry in Cold Spring, New York. He created the first Parrott rifle (and corresponding projectile) in 1860 and patented it in 1861.Pritchard Jr, Russ A.Civil War Weapons and Equipment, p.82. Globe Pequit Press, 2003. . Daniel Treadwell, who developed a method for making built-up guns in early 1840s, tried to claim that his patent infringed on an earlier one, but in 1866 S.D.N.Y. court dismissed it, deciding that Treadwell's claim was invalidated by a 1843 British patent to John Frith. Parrotts were manufactured with a combination of cast and wrought iron. The cast iron made for an accurate gun, but was brittle enough to suffer ...

Muzzle-loading Rifle
A muzzle-loading rifle is a muzzle-loaded small arm or artillery piece that has a rifled barrel rather than a smoothbore. The term "rifled muzzle loader" typically is used to describe a type of artillery piece, although it is technically accurate for small arms as well. A shoulder arm is typically just called a "rifle", as almost all small arms were rifled by the time breechloading became prevalent. Muzzle and breechloading artillery served together for several decades, making a clear distinction more important. In the case of artillery, the abbreviation " RML" is often prefixed to the guns designation; a Rifled breech loader would be "RBL", or often just "BL", since smoothbore breechloading artillery is almost nonexistent (except in tank guns). A muzzle loading weapon is loaded through the muzzle, or front of the barrel (or "tube" in artillery terms). This is the opposite of a breech-loading weapon or rifled breechloader (RBL), which is loaded from the breech-end of the barrel. ...

HMS Edinburgh (1882)
HMS ''Edinburgh'' was an ironclad battleship of the ''Colossus'' class which served in the Royal Navy of the Victorian era. She was the sister ship of HMS ''Colossus'', being started before her but being completed after. ''Edinburgh'' was the first British battleship since HMS ''Warrior'', launched in 1860, to carry breech-loading artillery as part of her main armament. ''Warrior'' had been equipped with 10 110-pounder Armstrong breech-loading guns, which had not proved satisfactory, to complement her 26 muzzle-loaders. ''Edinburgh''s guns were carried in two turrets positioned near the centre of the ship, and the turrets were mounted ''en echelon''. It was expected that, by mounting the turrets in this way, at least one gun from each turret could fire fore and aft along the keel line, and all four guns could fire on broadside bearings; it was intended that every part of the horizon could be covered by at least two guns. In practice it was found that firing too close to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hang Fire
Hang fire refers to an unexpected delay between the triggering of a firearm and the ignition of the propellant. This failure was common in firearm actions that relied on open primer pans, due to the poor or inconsistent quality of the powder. Modern firearms are also susceptible. The delay is usually too brief to be noticed, but can be several seconds. A hangfire should be suspected whenever a firearm fails to fire, but has not clearly malfunctioned. Ignition sequence The ignition train of modern firearms begins with detonation of a small quantity of impact-sensitive primary explosive in a primer in cartridge firearms or in a percussion cap in muzzleloaders. The energy released by this detonation is intended to ignite the propellant charge of gunpowder or smokeless powder. Primary explosives may deteriorate with age so they release less energy; and propellants damaged by moisture or lubricants may require more energy to ignite. These conditions may either delay the ignition seque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HMS Thunderer (1872)
HMS ''Thunderer'' was one of two turret ships built for the Royal Navy in the 1870s. She suffered two serious accidents before the decade was out and gained a reputation as an unlucky ship for several years afterward. The ship was assigned to the Mediterranean Fleet in 1878 and was reduced to reserve in 1881 before being recommissioned in 1885. ''Thunderer'' returned home in 1887 and was again placed in reserve. She rejoined the Mediterranean Fleet in 1891, but was forced to return to the UK by boiler problems the following year. The ship became a coast guard ship in Wales in 1895 and was again placed in reserve in 1900. ''Thunderer'' was taken out of service in 1907 and sold for scrap in 1909. Background and description The ''Devastation'' class was designed as an enlarged, ocean-going, version of the earlier . The ships had a length between perpendiculars of and were long overall. They had a beam of , and a draught of . The ''Devastation''-class ships displaced . T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Ordnance Terms
This article explains terms used for the British Armed Forces' ordnance (i.e.: weapons) and also ammunition. The terms may have slightly different meanings in the military of other countries. BD Between decks: applies to a naval gun mounting in which part of the rotating mass is below the deck, and part of it is above the deck. This allows for a lower profile of turret, meaning that turrets need not be superfiring (i.e. they can be mounted on the same deck and not obstruct each other at high angles of elevation.) BL The term BL, in its general sense, stood for breech loading, and contrasted with muzzle loading. The shell was loaded via the breech (i.e. the gunner's end of the barrel, which opened) followed by the propellant charge, and the breech mechanism was closed to seal the chamber. Breech loading, in its formal British ordnance sense, served to identify the gun as the type of rifled breechloading gun for which the powder charge was loaded in a silk or cloth bag and the br ...
