Contrary to urban legend, an M-80 that contains 3,000 mg of powder is not equivalent to a quarter-stick of dynamite. Dynamite generally contains a stable nitroglycerin -based high explosive, whereas M-80s or any other kind of firecracker contain a low explosive powder, like flash powder or black powder.
The 37×145mmR was a series of rimmed-case, fixed-ammunition cannon shells for use in the 37mm Browning M4 autocannon.. The rapid strides in aircraft protection made it necessary to develop an aircraft weapon that would fire projectiles with greater explosive and armor-piercing qualities than smaller caliber weapons.
Black powder produces gas at a predictable rate unaffected by pressure, while the gas production rate of smokeless powder increases with increasing pressure. [6] The possibility of runaway pressures caused smokeless powder to destroy many firearms designed for black powder and required much more precise measurement of propellant charges.
The term black powder 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 ...
Manufactured high-quality "fast-burning" black-powder and black powder cartridges until 1973, when it ran out of the specialized charcoal to produce it. Had its head office in London and its factory in Hounslow, later acquiring powdermills in Bedfont , North Feltham , and Tonbridge .
Propellants packaged in small sheet metal canisters for sale to civilians were labeled Military Rifle Powder to distinguish the product from low-density "bulk" propellants intended to react at lower pressures in shotguns or pistols and from Sporting Rifle Powder for early lever-action rifles unable to withstand the pressures of 20th-century ...
Gunpowder ("black powder") was the primary propellant before the invention of smokeless powder during the late 19th century. Cannons vary in gauge, effective range, mobility, rate of fire, angle of fire and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the ...
The 100-ton gun (also known as the Armstrong 100-ton gun) [6] was a british coastal defense gun and is the world's largest black powder cannon. It was a 17.72-inch (450 mm) rifled muzzle-loading (RML) gun made by Elswick Ordnance Company, the armaments division of the British manufacturing company Armstrong Whitworth, owned by William Armstrong.
