The Definition of Cordite
A family of smokeless propellants developed and produced in the United Kingdom from 1889 to
replace gunpowder as a military propellant. Like gunpowder, cordite is classified as a low
explosive because of its slow burning rates and consequently low brisance.
The hot gases produced by burning gunpowder or cordite generate sufficient pressure to propel a bullet or shell to its target,
but not enough to destroy the barrel of the firearm, or gun.
19 Other Firearms Definitions You Need To Know
A magnifying tube through which the shooter may see the target and aim the firearm. Scopes contain a reticle, commonly in the shape of a cross, which must be properly centered upon the target for accurate aim.
The rear portion of the barrel or firing cylinder in which the cartridge is inserted prior to being fired.
Rifles and pistols generally have a single chamber in their barrels,
while revolvers have multiple chambers in their cylinders and no chamber in their barrel.
The angle of the butt of a gun in relation to the line of sight.
Pitch is measured by resting the gun with its butt flat on a floor, the top of the receiver against a wall and its muzzle pointing up.
The distance of the muzzle from the wall is the gun's pitch down.
A gun holder that may be strapped to a human body, or affixed to the inside of a pack or bag, or dropped into a pocket.
A holster serves to protect the gun's mechanisms and finish, to provide security by covering the trigger so it cannot be pulled inadvertently,
and to present the grip of the gun at a constant angle for easy access. Some holsters also serve to obscure the outline of the
gun so it may be more easily concealed. Typically made from leather or in plastic.
A large piece of curved metal at the top of the grip on a pistol which protects the user's hand from getting "bitten" by the hammer or slide.
It is nearly always the top part of the grip safety commonly found on many 1911-style pistols.
Small spherical projectiles loaded in shotshells and more often called "shot."
The process of carving out recesses in wooden stocks with precision, using gouges, chisels and scrapers to accept the steel components of a firearm.
On guns (mainly shotguns) that have two barrels, there is a trigger for each barrel that work independently from each other.
The steel skeleton of the forend (above), into which any moving parts are fitted and which mates to and revolves about the action knuckle when the gun is opened.
In a handgun that does not have a hammer, the striker is a linear driven, spring loaded cylindrical part which strikes the primer of a chambered cartridge.
The striker replaces both the hammer and firing pin found in hammer driven pistols.
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 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.
The rear end of a rifle or shotgun. (The portion that rests against the shoulder.)

shotgun. By inserting different choke tubes, one can alter the shot pattern thrown by the
Generally refers to the stock and fore-end of a rifle. Can sometimes also be applied to any detachable accessories like a flashlight.
Targets that do something when you hit them, such as fall over, burst, send up smoke, or make a noise.
The tendency of a firearm when fired to move backwards, and a little upwards as a reaction to the force of the projectile moving down the barrel.
As Newton says, to every action there is always an equal and opposite reaction. The mass of the firearm provides some inertia to counteract the momentum of recoil.
What remains is absorbed by at the shoulder or the hand. The heavier the gun, the less the recoil. The more powerful the cartridge, the more the recoil.
A higher quality item used to increase accuracy, generally used for competition in a match. Match grade ammo and barrels are the most common improvements made to a firearm to improve accuracy for competition.
Also known as peep sights, range from the ghost ring sight, whose thin ring blurs to near invisibility (hence ghost), to target aperture sights that use large disks or other occluders with pinhole-sized apertures. In general, the thicker the ring, the more precise the sight, and the thinner the ring, the faster the sight.
