The combustion products of smokeless powder are mainly gaseous, compared to around 55% solid products (mostly potassium carbonate, potassium sulfate, and potassium sulfide) for black powder. [1] In addition, smokeless powder does not leave the thick, heavy fouling of hygroscopic material associated with black powder that causes rusting of the ...
Alliant Techsystems Inc. (ATK) was an American aerospace and arms manufacturer headquartered in Arlington County, Virginia. The company operated across 22 states, Puerto Rico , and internationally. ATK revenue in fiscal year 2014 was about US$4.8 billion.
A black powder substitute is a replacement for black powder (gunpowder), primarily used in muzzleloading firearms. Substitutes may have slightly different properties from gunpowder such as: reduced sensitivity as an explosive, increased efficiency as a propellant powder, different density, and/or reduced ignition efficiency.
Allegany Ballistics Laboratory (ABL) located in Rocket Center, West Virginia, is a diverse industrial complex employing some 1,000 people across 1,628 acres (6.59 km 2).The facility is a member of the Federal Laboratory Consortium and is operated by Northrop Grumman (former Alliant Techsystems) under contract with the Naval Sea Systems Command (NAVSEA).
The firm's first shipment was part of a defense contract to make primers using chlorate FA-70. CCI later moved on to much safer formulas for sporting ammunition. CCI provided the first reliable supply of primers for hobby reloaders. [2] As of February 2015, it was a subsidiary of Vista Outdoor, a spinoff of Alliant Techsystems. [3]
Components of a modern bottleneck rifle cartridge. Top-to-bottom: Copper-jacketed bullet, smokeless powder granules, rimless brass case, Boxer primer.. Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components (metallic/polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded ...

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.
