The Definition of Black Powder

Arsenal Exchange - Firearms Classifieds - Industry Directory

Black Powder

Also known as Gun Powder. A mixture of sulfur, charcoal, and potassium nitrate. It burns rapidly, producing a volume of hot gas made up of carbon dioxide, water, and nitrogen, and a solid residue of potassium sulfide. Because of its burning properties and the amount of heat and gas volume that it generates, gunpowder has been widely used as a propellant in firearms and as a pyrotechnic composition in fireworks. Modern firearms do not use the traditional black powder described here, but instead use smokeless powder.


19 Other Firearms Definitions You Need To Know


Quaker Gun

Not really a gun at all. During the U.S. Civil War, both sides would take tree branches or tree trunks, paint them black, and position them so that they appeared to be rifles or artillery pieces. By doing so, they could fool the other side into believing that they had more artillery than they really did.

Reticle

A matrix of dots, posts or lines, visible inside a rifle's telescopic sight, normally adjustable via exterior knobs for windage and elevation. After careful adjustment at a known range, the shooter aims the rifle by superimposing this matrix onto the target. With good estimation or range, cooperation from the wind, a clear eye and a steady hand, he may have a reasonable expectation of hitting his target.

Rifle

A shoulder-fired long gun which has a rifled barrel.

Open Frame

Refers to a revolver frame that has no top-strap over the cylinder.

Quarter Master

The person who supervises stores and distributes supplies and provisions.

COM

Abbreviation for Center Of Mass.

Mirage

A tendency for layers of air of different temperatures near the warm ground to cause refraction in the line of sight and disturbance of the perceived point of aim.

Airsoft (Air Soft)

A type of airgun that shoots spherical non-metallic pellets.

Luger

American name for the German "Parabellum" semiautomatic pistol introduced in 1900. The Parabellum was designed by Georg Luger, and based on the earlier Borchardt pistol. The official German military nomenclature was "Pistole '08" or "Po8." At first, it was chambered for the 7.65mm Parabellum round. Soon, it was modified to use the 9mm Parabellum cartridge, which is what most people refer to today when talking about a 9mm cartridge. "Luger" is now a trademark owned by the Stoeger Arms Co.

Mouse Gun

A name for any palm sized handgun which fires a small caliber.

Trigger

The small lever on a cartridge firearm, which one pulls to cause the spring-loaded firing pin to impact the primer, causing the gun to discharge. Normally, the trigger simply connects to the sear. Pulling the trigger moves the sear out of its notch, releasing the spring-loaded hammer to strike the firing pin which in turn strikes the primer; or the coilspring-loaded firing pin directly. Other, often-Germanic systems have their own miniature lockwork which, when cocked, allows an exceedingly light trigger pull to discharge the firearm, a setting that would be perilous to carry in the field.

Point of Impact

The point where the projectile from a firearm hits.

Clearing

Unloading a gun and double checking that it is unloaded or fixing a malfunction so that the gun is ready to fire again.

Browning

John Moses Browning was born in Ogden, Utah on January 23, 1855, and was an American firearms designer who developed many varieties of military and civilian firearms, cartridges, and gun mechanisms, many of which are still in use around the world. Almost all of his design concepts can be found in some form or another in every modern automatic and semi-automatic firearm. He is regarded as one of the most successful firearms designers of the 20th century, in the development of modern automatic and semi-automatic firearms, and is credited with 128 gun patents. He made his first firearm at age 13 in his father's gun shop, and was awarded his first patent on October 7, 1879 at the age of 24.
The Browning Arms Company was founded in 1878 by John Moses Browning and his brother Matthew Sandifer Browning. The company was founded to market the sporting (non-military) designs of John Moses Browning. The company still exists today mostly manufacturing world class shotguns.

Autoloader

A firearm that automatically loads the next cartridge to be fired into the chamber either upon the pull of the trigger in an open bolt design or upon the firing of the previous round in a close bolt design.
Autoloader should not be confused with Automatic or Semi-Automatic since the term Autoloader only applies to how the next round is chambered not how many rounds can be fired per trigger pull. All Automatic and Semi-Automatic firearms are autoloaders. Revolvers, bolt action, lever action and pump action firearms are not autoloaders.

Line Of Sight

An imaginary straight line from the eye through the sights of a firearm to the target.

Lock Speed

The same as Lock Time

Double Action

An action type that when the trigger of a gun is pulled, the gun gets cocked and the hammer (or striker) is dropped. This applies to both revolvers and semi-automatic guns. On a double action revolver, when the trigger is pulled, the hammer is cocked before releasing. With a double-action semi-automatic pistol, the hammer does not have to be manually cocked (via actually pulling back the trigger or tracking the slide), the hammer (or striker) will be cocked while the trigger is being pulled. A firearm that only the hammer drops when the trigger is pulled is a single action gun.

Thunder

With the execption of the BP model series, Thunder is the name of all of Bersa's pistols. The line currently consists of three frames.

• The Thunder .380 series, which is a very reliable and good looking compact blowback system .380 acp pistol (there is also a .22lr version).
• The full size Thunder Pro series (avalable in 9mm and .40 S&W) is a locked breech design.
• The Thunder Ultra Compact Pro series, locked breech, short recoil design which is more of a commander size Thunder Pro (available in 9mm, .40 S&W, and .45 acp).
The Bersa Thunders are well known among firearms enthusiasts for being extremely high quality guns at reasonable prices.
