Burst barrel of a muzzle loader pistol replica, which was loaded with nitrocellulose powder instead of black powder and could not withstand the higher pressures of the modern propellant The development of smokeless powders, such as cordite , in the late 19th century created the need for a spark-sensitive priming charge , such as gunpowder.
Finnish smokeless powder. Smokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to black powder. Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder.
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.
Cordite is a family of smokeless propellants developed and produced in Britain since 1889 to replace black powder as a military firearm propellant. Like modern gunpowder, cordite is classified as a low explosive because of its slow burning rates and consequently low brisance [ not verified in body ] .
The Dudley-Sims dynamite gun used a smokeless powder charge to compress the air. Beneath the gun barrel was a cylinder into which the powder charge was loaded. When fired, the expanding gas from the smokeless powder compressed the air in the cylinder, which was then fed into the gun barrel, accelerating the explosive projectile.
Where RS (Rifle/Shotgun) is equivalent to FFg black powder and P (Pistol) is equivalent to FFFg black powder on the Fg (coarsest) to FFFFg (finest) granularity scale. While Pyrodex offers improved safety and increased efficiency (in terms of shots per pound of powder) over black powder, the level of fouling is similar to black powder as Pyrodex ...
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. [10]
The odd, highly tapered 8 mm Lebel, made by necking down an older 11 mm black-powder cartridge, was introduced in 1886, and it was soon followed by the 7.92×57mm Mauser and 7×57mm Mauser military rounds, and the commercial .30-30 Winchester, all of which were new designs built to use smokeless powder. All of these have a distinct shoulder ...
