History

Large-scale ball propellant manufacture began during World War II at the Olin Corporation plant in East Alton, Illinois. Population growth of the St. Louis, Missouri, metropolitan area encouraged finding a more remote location for a modern production plant. The St. Marks manufacturing facility was built in 1969 on a large plot of undeveloped swampland south of Tallahassee, Florida, at near sea-level elevation between the St. Marks River and the Gulf Coast. [5] Plant operation was transferred to St. Marks Powder in 1998. [6]

Products

St. Marks Powder supplies nearly 100 percent of the propellant used in 5.56×45mm NATO, 7.62×51mm NATO, 9×19mm NATO, and .50 BMG ammunition for United States military small arms and 20mm ammunition for the M61 Vulcan aircraft cannon. [3] Similar propellants are sold to commercial manufacturers of rimfire and centerfire ammunition [1] or marketed by Alliant Powder, [3] Winchester, and Hodgdon Powder Company for civilian handloading. [7] Other propellants are used for military 60mm and 81mm mortar rounds, [3] rocket-assisted projectiles, [8] or dispersing non-lethal agents used for crowd control, marking, or area denial. [9]

The 5.56×45mm NATO is a rimless bottlenecked centerfire intermediate cartridge family developed in the late 1970s in Belgium by FN Herstal. It consists of the SS109, L110, and SS111 cartridges. On 28 October 1980, under STANAG 4172, it was standardized as the second standard service rifle cartridge for NATO forces as well as many non-NATO countries. Though they are not identical, the 5.56×45mm NATO cartridge family was derived from and is dimensionally similar to the .223 Remington cartridge designed by Remington Arms in the early 1960s.

A cartridge, also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile, a propellant substance and an ignition device (primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often used to refer to a complete cartridge, the correct usage only refers to the projectile.

<span class="mw-page-title-main">Smokeless powder</span> Type of propellant

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. The combustion products of smokeless powder are mainly gaseous, compared to around 55% solid products for black powder. In addition, smokeless powder does not leave the thick, heavy fouling of hygroscopic material associated with black powder that causes rusting of the barrel.

The .223 Remington is a rimless, bottlenecked, centerfire intermediate cartridge. It was developed in 1957 by Remington Arms and Fairchild Industries for the U.S. Continental Army Command of the United States Army as part of a project to create a small-caliber, high-velocity firearm. The .223 Remington is considered one of the most popular common-use cartridges and is used by a wide range of semi-automatic and manual-action rifles.

The Sporting Arms and Ammunition Manufacturers' Institute is an association of American manufacturers of firearms, ammunition, and components. SAAMI is an accredited standards developer that publishes several American National Standards that provide safety, reliability, and interchangeability standards for commercial manufacturers of firearms, ammunition, and components. In addition, SAAMI publishes information on the safe and responsible transportation, storage, and use of those products.

The .30-06 Springfield cartridge, 7.62×63mm in metric notation, and called the .30 Gov't '06 by Winchester, was introduced to the United States Army in 1906 and later standardized; it remained in military use until the late 1970s. In the cartridge's name, ".30" refers to the nominal caliber of the bullet in inches; "06" refers to the year the cartridge was adopted, 1906. It replaced the .30-03 Springfield, 6mm Lee Navy, and .30-40 Krag cartridges. The .30-06 remained the U.S. Army's primary rifle and machine gun cartridge for nearly 50 years before being replaced by the 7.62×51mm NATO and 5.56×45mm NATO, both of which remain in current U.S. and NATO service. The cartridge remains a very popular sporting round, with ammunition produced by all major manufacturers.

<span class="mw-page-title-main">Overpressure ammunition</span> Type of small arms ammunition

Overpressure ammunition, commonly designated as +P or +P+, is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber, but less than the pressures generated by a proof round. This is done typically to produce ammunition with higher muzzle velocity, muzzle energy, and stopping power, such as ammunition used for security, defensive, or hunting purposes. Because of this, +P ammunition is typically found in handgun calibers which might be used for paramilitary forces, armed security, and defensive purposes.
