Ball And Shot Gun
The ball and shot gun, often also known by the marketing name paradox gun, is a shotgun capable of firing both Shot (pellet), shot and Bullet, solid projectiles. First built by Holland and Holland, the term paradox is a proprietary name applied to these guns by Holland and Holland. Design Ball and shot guns resemble side by side double-barrelled shotguns, typically with pistol grips and flip up sights. The ball and shot gun has broad, shallow rifling in the chokes of smoothbore shotgun barrels. Ball and shot retained the ability to fire shotgun shells, whilst being able to fire useful bullets accurately at short ranges, in a gun of manageable weight. A typical 12 bore ball and shot gun weighed , whilst a fully rifled 12 bore rifle would weigh over . Ball and shot guns were available in a variety of calibres, from 8 bore to 28 bore. The original 12 bore loading from Holland and Holland fired a pure lead bullet that was accurate to ranges up to , Westley Richards developed a 12 bo ...

Paradox Muzzle
A paradox is a logically self-contradictory statement or a statement that runs contrary to one's expectation. It is a statement that, despite apparently valid reasoning from true or apparently true premises, leads to a seemingly self-contradictory or a logically unacceptable conclusion. A paradox usually involves contradictory-yet-interrelated elements that exist simultaneously and persist over time. They result in "persistent contradiction between interdependent elements" leading to a lasting "unity of opposites". In logic, many paradoxes exist that are known to be Validity (logic), invalid arguments, yet are nevertheless valuable in promoting critical thinking, while other paradoxes have revealed errors in definitions that were assumed to be rigorous, and have caused axioms of mathematics and logic to be re-examined. One example is Russell's paradox, which questions whether a "list of all lists that do not contain themselves" would include itself and showed that attempts to foun ...

Leopard
The leopard (''Panthera pardus'') is one of the five extant cat species in the genus ''Panthera''. It has a pale yellowish to dark golden fur with dark spots grouped in rosettes. Its body is slender and muscular reaching a length of with a long tail and a shoulder height of . Males typically weigh , and females . The leopard was first described in 1758, and several subspecies were proposed in the 19th and 20th centuries. Today, eight subspecies are recognised in its wide range in Africa and Asia. It initially evolved in Africa during the Early Pleistocene, before migrating into Eurasia around the Early–Middle Pleistocene transition. Leopards were formerly present across Europe, but became extinct in the region at around the end of the Late Pleistocene-early Holocene. The leopard is adapted to a variety of habitats ranging from rainforest to steppe, including arid and montane areas. It is an opportunistic predator, hunting mostly ungulates and primates. It relies on it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rifles
A rifle is a long-barreled firearm designed for accurate shooting and higher stopping power, with a barrel that has a helical or spiralling pattern of grooves ( rifling) cut into the bore wall. In keeping with their focus on accuracy, rifles are typically designed to be held with both hands and braced firmly against the shooter's shoulder via a buttstock for stability during shooting. Rifles are used in warfare, law enforcement, hunting and target shooting sports. The invention of rifling separated such firearms from the earlier smoothbore weapons (e.g., arquebuses, muskets, and other long guns), greatly elevating their accuracy and general effectiveness. The raised areas of a barrel's rifling are called ''lands''; they make contact with and exert torque on the projectile as it moves down the bore, imparting a spin. When the projectile leaves the barrel, this spin persists and lends gyroscopic stability to the projectile due to conservation of angular momentum, i ...

Multiple-barrel Firearms
A multiple-barrel firearm is any type of firearm with more than one gun barrel, usually to increase the rate of fire or probability of kill, hit probability and to reduce barrel erosion or overheating. History Volley gun Multiple-barrel firearms date back to the 14th century, when the first primitive volley guns were developed. They are made with several single-shot gun barrel, barrels assembled together for firing a large number of shots, either simultaneously or in quick succession. These firearms were limited in firepower by the number of barrels bundled, and needed to be manually prepared, ignited, and reloaded after each firing. In practice the large volley guns were not particularly more useful than a cannon firing canister shot or grapeshot. Since they were still mounted on a carriage, they could be as hard to aim and move around as a heavy cannon, and the many barrels took as long (if not longer) to reload.Matthew Sharpe "Nock's Volley Gun: A Fearful Discharge" ''A ...

Double-barreled Shotguns
A double-barreled shotgun, also known as a double shotgun, is a break-action shotgun with two parallel barrels, allowing two single shots that can be fired simultaneously or sequentially in quick succession. Construction Modern double-barreled shotguns, often known as ''doubles'', are almost universally break action, with the barrels hinge down at the rear to expose the breech ends for unloading and reloading. Since there is no reciprocating action needed to eject and reload the shells, doubles are more compact than repeating designs such as pump action, lever action, bolt action, or self-loading shotguns. Barrel configuration Double-barreled shotguns (specifically break-action), come in two basic configurations: * side-by-side (S×S) — the two barrels are arranged horizontally; * over-and-under (O/U) — the two barrels are arranged vertically. The original double-barreled guns were commonly all side-by-side designs, which was a more practical design for muzzleloaders ...

Double Rifle
The double rifle, also known as a double-barreled rifle, is a rifle with two barrels mounted parallel to each other that can be fired simultaneously or sequentially in quick succession. Synonymous with big game hunting found primarily in Africa and Asia, the double rifle is a sporting weapon with very little military heritage. Design The double rifle is usually handcrafted and is considered by many to be the pinnacle of sporting rifle design. It is not designed for long-range accuracy but instead for the security of an immediate second shot. Double rifles are similar to double-barreled shotguns. Action As with double-barrelled shotguns, modern double rifles are all made with either sidelock or boxlock actions, although occasionally old hammer rifles can be found. The majority of double rifles have been built on the boxlock actions as it is a simpler design with fewer moving parts that can fail. Consequently, it has an outstanding reputation for reliability. The sidelock actio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Naval Air Service
The Royal Naval Air Service (RNAS) was the air arm of the Royal Navy, under the direction of the Admiralty (United Kingdom), Admiralty's Air Department, and existed formally from 1 July 1914 to 1 April 1918, when it was merged with the British Army's Royal Flying Corps to form the Royal Air Force (RAF), the world's first independent air force. It was replaced by the Fleet Air Arm, initially consisting of those RAF units that normally operated from ships, but emerging as a separate unit similar to the original RNAS by the time of the Second World War. History Background On 21 July 1908 Captain Reginald Bacon, who was a member of the Aerial Navigation Sub-Committee, submitted to the First Sea Lord John Fisher, 1st Baron Fisher, Sir John Fisher that a rigid airship based on the Imperial Germany, German Zeppelin be designed and constructed by the firm of Vickers. After much discussion on the Committee of Imperial Defence the suggestion was approved on 7 May 1909. Though Bacon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeppelin
A Zeppelin is a type of rigid airship named after the German inventor Ferdinand von Zeppelin () who pioneered rigid airship development at the beginning of the 20th century. Zeppelin's notions were first formulated in 1874Eckener 1938, pp. 155–157. and developed in detail in 1893.Dooley 2004, p. A.187. They were patented in German Empire, Germany in 1895 and in the United States in 1899. After the outstanding success of the Zeppelin design, the word ''zeppelin'' came to be commonly used to refer to all forms of rigid airships. Zeppelins were first flown commercially in 1910 by Deutsche Luftschiffahrts-AG (DELAG), the world's first airline in revenue service. By mid-1914, DELAG had carried over 10,000 fare-paying passengers on over 1,500 flights. During World War I, the German military made extensive use of Zeppelins German strategic bombing during World War I, as bombers and aerial reconnaissance in World War I, as scouts.

Harald George Carlos Swayne
Colonel Harald George Carlos Swayne (1860–1940) was a British soldier, explorer, naturalist and big game hunter, he was the older brother of Eric John Eagles Swayne. Military career Commissioned into the Royal Engineers and commencing his service in India, between 1884 and 1897 Swayne made a number of expeditions to Africa to make exploratory surveys for the British authorities. First travelling to Somaliland in January 1885 to hunt, Swayne made seventeen trips to Somaliland on leaves of absence from the Indian Army to conduct surveys, hunt and explore, making various notes on the local wildlife and inhabitants. In August 1885, the Indian Government sent Swayne to conduct a reconnaissance of Somaliland, a task that lasted until July 1887, the notes and maps he made during this period proved invaluable during the subsequent Somaliland Campaign. Later Swayne served with the Imperial British East Africa Company. During the Great War, Swayne was recalled to active service ...
