Hodgdon's product line includes Pyrodex and Triple Seven, which are modern substitutes for black powder and intended for use in muzzleloaders and certain antique firearms. Consequences of black powder's easy ignition by sparks or static electricity make manufacture and storage hazardous. The sole factory of the United States' largest 20th ...
There are 7,000 grains in one pound. Black powder substitutes are formulated to be a volume-for-volume equivalent of black powder, not an equivalent mass-for-mass (weight-for-weight). Black powder substitutes are measured by volumetric measurement techniques, not in grains on a scale, due to the difference in density compared to black powder.
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 ...
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 .50-90 Sharps (13x64mmR), also known as the .50-2 1 ⁄ 2" Sharps, is a black-powder rifle cartridge that was introduced by Sharps Rifle Manufacturing Company in 1872 as a buffalo (American bison) hunting round. Like other large black-powder rounds, it incorporates a heavy bullet and a large powder volume, leading to high muzzle energies.
The .577 Black Powder Express was the go-to dangerous game caliber from the 1870s through 1900. It spawned the .577 Express around 1890, which used smokeless cordite instead of black powder, and then the .577 Nitro Express in 1900, which used modern metal jacketed and solid bullets pushed by more modern smokeless powders.
The .450 Black Powder Express is a rimmed, straight walled, centerfire rifle cartridge designed for use with blackpowder. It was available in a number of loadings with bullets weighing from 270 to 365 grains (17.5 to 23.7 g), all driven by 120 grains (7.8 g) of black powder.
The 3-inch and 3 1 ⁄ 4-inch .500 BPE cartridges have survived to the current day as the .500 3-inch Nitro for Black and the .500 3 1 ⁄ 4-inch Nitro for Black, the same cartridges loaded with mild loadings of modern smokeless powder, carefully balanced through trial to replicate the ballistics of the Black powder version.
