The Definition of 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
A malfunction in which the spent case fails to eject from a semi-automatic firearm and blocks the chamber.
As the fresh round is brought forward it cannot enter the chamber. It is cleared by
stripping the magazine from the gun, racking the slide several times to eject the spent case, and then reloading.
A bullet designed with a full diameter flat point. It is primarily used in target competition because it cuts a clean round hole in paper targets that aids in scoring the target.
A type of curve represented by the curved section of a bullet between its bearing surface and its tip.
A small lever mounted to the cocking piece of a Winchester Model 70 rifle, rotating on a vertical axis from front (Fire),
halfway back (Safe, but allowing bolt movement), and fully back (Bolt and firing pin locked Safe).
While, like the Mauser, commendable for locking the firing pin instead of just the trigger,
its fore and aft movement is both easier to operate and it allows lower mounting of telescopic sights,
reducing parallax between the line of sight and the line of the bore and increasing the range of
distances for which the scope may be reliably sighted-in.
A fired case has marks upon it that it picked up from the extractor, ejector, and breechface of the gun when the shot went off.
A bullet fired through a rifled barrel also has rifling marks unique to the barrel that launched it. A record of these marks, when stored in a central database,
is called a ballistic fingerprint. Some states require this record to be made by law, so that individual guns can be located from bullets or casings found at the scene of a crime.
A swing-out arm on a revolver, to which the cylinder is
mounted when opened facilitates loading and cleaning.
A condition (status) of a shooting range that shooters may commence to fire.
Abbreviation for Concealed Firearms License.
A semi-automatic firearm whose breechblock and barrel are not mechanically locked together when fired.
In such case the breechblock immediately begins to separate from the barrel upon firing.
Blowback is used in comparatively low powered weapons, in which inertia of the breechblock, and cartridge wall adhesion against the chamber,
are sufficient enough to retard opening until breech gas pressures have fallen to a safe level.
Firearms designed to be carried and used by an individual or individuals.
A horizontal wedge, press-fit through the forend of a vintage gun, through a lump
attached to the underside of the barrel and out the other side of the forend.
To secure the forend in position. Also called a crosspin or a wedge fastener.
A type of firearms magazine that is cylindrical in shape, similar to a drum.
Probably the most recognizable drum magazine is the magazine for a Thompson carbine rifle, also known as the Tommy Gun.
Short for the word Ambidextrous. Meaning that a feature of a firearms can be used by either hand, for example ambi-safety, ambi slide catch or ambi mag release.
A stout flange, invariably incorporated into the underside of the front receiver ring of a bolt action, and also frequently
incorporated into the underside of the barrel of a heavily-recoiling rifle, which when properly bedded, transfers recoil to the stock.
The substance which imparts movement to the projectile in a firearm. In a firearm, usually powder. In an airgun the propellant is air or Co2
A device fitted inside the buttstock of a heavily-recoiling gun or rifle, usually containing mercury and a valve. As the gun recoils,
the mercury is displaced temporarily, increasing the duration, and thus diminishing the perceived impact of the recoil.
The added half-pound of weight doesn#39;t hurt either.
A type of backstop that catches the fired bullet and prevents it from exiting the area. Bullet traps are most commonly used on indoor ranges.
A semi-automatic is said to be out of battery when the slide fails to come all the way forward again after the
gun has fired. This condition can be created by a misfeed, a dirty gun, weak springs, the shooter's
thumbs brushing against the slide, riding the slide, or any of several other causes.
