The C was to indicate the powder burned "cooler" than traditional Improved Military Rifle (IMR) powders. [4] In 1949, he began acquisition of powder salvaged from disassembled Oerlikon 20mm cannon cartridges. This powder resembled IMR 4350 in appearance, and with a slower burning rate, was initially marketed as "4350 Data", and later as 4831. [5]
John Olin, the son of founder Franklin W. Olin, improved shotgun cartridge designs in the 1920s by using harder shot and progressive burning powder. [9] Western produced 3 billion rounds of ammunition in World War II, and the Winchester subsidiary developed the U.S. M1 carbine and produced the carbine and the M1 rifle during the war.
Unique is a gray flake powder introduced by Laflin & Rand in 1900. [22] Individual flakes are approximately 1.5 mm (0.06 inch) in diameter. [ 24 ] It is designed for shotguns and can be used in handguns.
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 ...
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.
While shotguns had been used in earlier conflicts, the trench warfare of World War I demonstrated a need for standardized weapons and ammunition. [2] Initial issue with each shotgun was one hundred commercial-production paper-cased shotgun shells containing nine 00 buckshot pellets 0.33 inches (8.4 mm) in diameter.
Manufacturing facilities were dispersed along the 2-mile (3.2 km) power canal to minimize damage during infrequent explosions. King's son-in-law Gershom Moore Peters began working at the powder mill in 1881 and became president of the powder company when King died in 1885. Peters formed the Peters Cartridge Company at Kings Mills in 1887.
Ball propellant (trademarked as Ball Powder by Olin Corporation and marketed as spherical powder by Hodgdon Powder Company [1]) is a form of nitrocellulose used in small arms cartridges. Ball propellant can be manufactured more rapidly with greater safety and less expense than extruded propellants.
