The Definition of Smokeless Powder
The propellant powder used in modern ammunition. It is not an explosive, but rather a flammable solid that burns extremely rapidly releasing a
large volume of gas. Commonly called "gunpowder" and usually made from nitrocellulose, or nitrocellulose and nitroglycerin.
It is classified as a "Flammable Solid" by the Department of Transportation.

The amount of rearward force exerted by the propellant gases on the bolt or breech of a firearm action or breech when a projectile is fired.
The applied force has both magnitude and direction, making it a vector quantity.
The arc described by a projectile (or a load of shot) after it exits the muzzle of a firearm. Falling objects accelerate downwards at a rate of 32 feet per second, per second.
The faster a projectile travels, the greater the distance it can cover in a given time before dropping too far. Hence, the higher the velocity of a bullet, the flatter the trajectory it will achieve.
A repeating firearm in which the ammunition is held in a multi-chambered cylinder, which is rotated to bring each chamber in line with
the barrel. Most revolvers are handguns, although shoulder-fired arms have been made using this sort of mechanism.
Abbreviation for 'Back Up Gun'
A type of firearm in which the action is in the open position and the chamber empty prior to firing.
When the trigger is pressed the bolt moves forward, chambering a cartridge and firing it and returning
to the open position. When firing is stopped the bolt remains open and the chamber empty.
A rear barrel sight base, more articulated than having the sight simply dovetailed into the barrel, but not requiring as much gunsmithing as having it mounted onto a proper quarter-rib.
Anything a person can hide behind that will probably stopp a bullet.
A series of projections on the bolt of a firearm designed to fit into corresponding slots in the receiver to lock the action in closed position for firing.
A Federal Firearms License (FFL) is a license in the United States that enables an individual or a company to engage in a business pertaining to
the manufacture of firearms and ammunition or the interstate and intrastate sale of firearms. Holding an FFL to engage in certain such activities has
been a legal requirement within the United States since the enactment of the Gun Control Act of 1968.
The relationship between a bullet's weight and its diameter. A long bullet, such as the original 7.62x54R
loading for the Mosin Nagant 91/30, will have a high sectional density and consequently greater
penetration than a shorter bullet of similar construction. A shorter bullet with less sectional
density will have relatively less penetration, but greater knockdown power.
A 1/60th part of a degree, the unit of measure used in adjusting rifle sights.
As it turns out conveniently, a minute of angle translates almost exactly to one inch at 100 yards
(actually 1.047 inches), to two inches at 200 yards and three inches at 300 yards
The amount of propellant powder that is suitable for specific cartridge-bullet combination,
or in the case of shotshells, for a specific weight of shot and wad column.
System of measurement for the internal bore diameter of a smooth-bore firearm based on the diameter of each of that
number of spherical lead balls whose total weight equals one pound.
The internal diameter of a 12 gauge shotgun barrel is therefore equal to the diameter of a lead
ball weighing 1/12 pound, which happens to be .729" (Or in British: Bore.) The Gauge/Bore system is also used, by convention, to describe the internal barrel diameter of large-bore,
19th century, English, single-shot and double-barrel rifles.
A spring-activated mechanism for the ejection of ammunition or and empty shell casing. On doubles, each barrel has a separate ejector.
A rapidly burning powder made by absorbing nitroglycerine into nitrocellulose (guncotton).
Also spelled blueing.
A passivation process in which steel is partially protected against rust, and is named after the blue-black appearance of the resulting protective finish.
True gun bluing is an electrochemical conversion coating resulting from an oxidizing chemical reaction with iron on the surface selectively forming magnetite
(Fe3O4), the black oxide of iron, which occupies the same volume as metallic iron. Bluing is most commonly used by gun manufacturers, gunsmiths and gun
owners to improve the cosmetic appearance of, and provide a measure of corrosion resistance to, their firearms.
Racking the slide incorrectly by allowing your hand to rest upon the slide as it moves forward during the loading procedure. Riding the slide is a common cause of misfeeds and other malfunctions.
