Hodgdon Powder Company
The Hodgdon Powder Company began in 1952 as B.E. Hodgdon, Inc., and has become a major distributor of smokeless powder for the ammunition industry, as well as for individuals who load their own ammunition by hand. The company's corporate office and manufacturing facilities are located in Kansas, United States. Hodgdon acquired IMR Powder Company in 2003. Winchester branded reloading powders have been distributed in the United States by Hodgdon since March 2006. Background In the opening days of World War II, a chemist friend of Bruce E. Hodgdon was casually reminiscing about World War I. He mentioned the quantities of surplus smokeless powder the military had dumped at sea after the war; and speculated how useful that would have been to handloaders struggling through the Great Depression. He anticipated a similar surplus powder situation might occur after World War II. Hodgdon began investigating availability of surplus powder when the war ended; and sales to handloaders b ...

Smokeless Powder
Finnish smokeless powderSmokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to gunpowder ("black powder"). The combustion products are mainly gaseous, compared to around 55% solid products (mostly potassium carbonate, potassium sulfate, and potassium sulfide) 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. Despite its name, smokeless powder is not completely free of smoke; while there may be little noticeable smoke from small-arms ammunition, smoke from artillery fire can be substantial. Originally invented in 1884 by Paul Vieille, the most common formulations are based on nitrocellulose, but the term was also used to describe various picrate mixtures with nitrate, chlorate, or dichromate oxidizers during the late 19th century, before the advantages of nitrocellulose beca ...

DuPont
DuPont de Nemours, Inc., commonly shortened to DuPont, is an American multinational chemical company first formed in 1802 by French-American chemist and industrialist Éleuthère Irénée du Pont de Nemours. The company played a major role in the development of Delaware and first arose as a major supplier of gunpowder. DuPont developed many polymers such as Vespel, neoprene, nylon, Corian, Teflon, Mylar, Kapton, Kevlar, Zemdrain, M5 fiber, Nomex, Tyvek, Sorona, Corfam and Lycra in the 20th century, and its scientists developed many chemicals, most notably Freon (chlorofluorocarbons), for the refrigerant industry. It also developed synthetic pigments and paints including ChromaFlair. In 2015, DuPont and the Dow Chemical Company agreed to a reorganization plan in which the two companies would merge and split into three. As a merged entity, DuPont simultaneously acquired Dow and renamed itself to DowDuPont on August 31, 2017, and after 18 months spin off the merged entity' ...

Black Powder Substitute
A black powder substitute is a replacement for black powder used in muzzleloading and cartridge firearms. Black powder substitutes offer a number of advantages over black powder, primarily including reduced sensitivity as an explosive and increased efficiency as a propellant powder. Types Hodgdon's ''Pyrodex'' was the first widely available substitute on the market. Pyrodex is less sensitive to ignition than black powder, and uses the same shipping and storage guidelines as smokeless powder. Pyrodex is more energetic per unit of mass than black powder, but it is less dense, and can be substituted at a 1:1 ratio by volume for black powder in many applications. Pyrodex is similar in composition to black powder, consisting primarily of charcoal, sulfur, and potassium nitrate, but it also contains graphite and potassium perchlorate, plus additional ingredients protected by trade secret. Originally available as loose powder in two granularities, RS (Rifle/Shotgun) equal to FFG ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Static Electricity
Static electricity is an imbalance of electric charges within or on the surface of a material or between materials. The charge remains until it is able to move away by means of an electric current or electrical discharge. Static electricity is named in contrast with current electricity, where the electric charge flows through an electrical conductor or space, and transmits energy. A static electric charge can be created whenever two surfaces contact and have worn and separated, and at least one of the surfaces has a high resistance to electric current (and is therefore an electrical insulator). The effects of static electricity are familiar to most people because people can feel, hear, and even see the spark as the excess charge is neutralized when brought close to a large electrical conductor (for example, a path to ground), or a region with an excess charge of the opposite polarity (positive or negative). The familiar phenomenon of a static shockmore specifically, an electros ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muzzleloader
A muzzleloader is any firearm into which the projectile and the propellant charge is loaded from the muzzle of the gun (i.e., from the forward, open end of the gun's barrel). This is distinct from the modern (higher tech and harder to make) designs of breech-loading firearms. The term "muzzleloader" applies to both rifled and smoothbore type muzzleloaders, and may also refer to the marksman who specializes in the shooting of such firearms. The firing methods, paraphernalia and mechanism further divide both categories as do caliber (from cannons to small-caliber palm guns). Modern muzzleloading firearms range from reproductions of sidelock, flintlock and percussion long guns, to in-line rifles that use modern inventions such as a closed breech, sealed primer and fast rifling to allow for considerable accuracy at long ranges. Modern mortars use a shell with the propelling charge and primer attached at the base. Unlike older muzzleloading mortars, which were loaded the same way as ...

Black Powder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good propellant but is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nobel Enterprises
Nobel Enterprises () is a chemicals business that used to be based at Ardeer, in the Ayrshire town of Stevenston, in Scotland. Specialising in nitrogen-based propellants and explosives and nitrocellulose-based products such as varnishes and inks. It was formerly ICI Nobel, a division of the chemicals group ICI, but was then sold to Inabata, a Japanese trading firm. The business was sold on to Chemring Group in 2005 and is now a Scottish Company (Chemring Energetics UK Ltd), part of Chemring Group. History Nobel Industries Limited was founded in 1870 by Swedish chemist and industrialist Alfred Nobel for the production of the new explosive dynamite in the United Kingdom. The factory was overseen and run by George McRoberts. McRoberts and John Downie raised the £24,000 needed to found the company rather than Nobel himself. It was chaired by the Glasgow shipbuilder, Charles Randolph (1809-1878). Ardeer, on the coast at Ayrshire, was chosen for the company's first factory. The bu ...

Vulcan Cannon
The M61 Vulcan is a hydraulically, electrically, or pneumatically driven, six-barrel, air-cooled, electrically fired Gatling-style rotary cannon which fires rounds at an extremely high rate (typically 6,000 rounds per minute). The M61 and its derivatives have been the principal cannon armament of United States military fixed-wing aircraft for over sixty years. The M61 was originally produced by General Electric. After several mergers and acquisitions, it is currently produced by General Dynamics. Development At the end of World War II, the United States Army Air Forces began to consider new directions for future military aircraft guns. The higher speeds of jet-powered fighter aircraft meant that achieving an effective number of hits would be extremely difficult without a much higher volume of fire. While captured German designs (principally the Mauser MG 213C) showed the potential of the single-barrel revolver cannon, the practical rate of fire of such a design was still lim ...
