The Definition of Headspace Gauge
Plugs of hardened steel, precisely machined in relation to the standard dimensional specifications of a given cartridge,
normally in sets of three: "GO", "No-Go" and "Field". By loading these plug-gauges into the chamber in succession,
one can check that the action should close on the "Go" gauge. It should not close on the "No-Go" gauge,
but might were enough force to be used. And, it absolutely should not close on the "Field" gauge.

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.
Targets that do something when you hit them, such as fall over, burst, send up smoke, or make a noise.
An early form of complete, self-contained cartridge. It included bullet, powder and ignition primer, all in one package.
The primer was located towards the base of the cartridge, but completely internally. The pin, shaped like a little finishing nail,
pointed on the inside end and resting on the internal primer, projected radially about a quarter-inch to the outside of the base of
the cartridge. When loaded, a pinfire gun showed the tips of the pins exposed through small slots in the tops of the breech faces of the barrels.
To fire, hammers fell on the pins, driving them (through the wall of the cartridge) into the internal primer.
The forward portion of a bottlenecked cartridge case. Also the portion of a rifle chamber in which the neck of the cartridge case rests.
A style of rear sight, typically used on rifles for either slow-moving bullets or for long ranges, whereby a ladder may be raised from
flush with the barrel to a vertical position, and which incorporates a sliding crossbar which may be moved vertically in order to achieve significant elevation.
The length, within a rifled barrel, required to accomplish one full rotation. 1:12 Twist, means a bullet passing down the bore would complete one revolution in twelve inches.
1:7 Twist, means a bullet passing down the bore would complete one revolution in seven inches, which makes it a tighter twist than 1:12.
Different weights of bullet require appropriate rates of twist.
A wildcat cartridge, or wildcat, is a custom cartridge for which ammunition and/or firearms are not mass-produced.
These cartridges are often created in order to optimize a certain performance characteristic (such as the power, size or efficiency) of an existing commercial cartridge.
Developing and using wildcat cartridges does not generally serve a purpose in military or law enforcement;
it is more a hobby for serious shooting, hunting, gunsmithing and handloading enthusiasts, particularly in the United States.
There are potentially endless amounts of different kinds of wildcat cartridges: one source of gunsmithing equipment has a library of over
6,000 different wildcat cartridges for which they produce equipment such as chamber reamers.
A larger class of machine gun..
A chemical phosphate process developed during the second world war to provide an economical, durable and non-reflective surface finish to military firearms.
Fouling of a firearm bore by metal particles from bullets adhering to the metal surface caused by heat or friction.
A tube, usually metal, through which a controlled explosion or rapid expansion of gases are released in order to propel a projectile out of the end at a high velocity.
It is the tube through which the bullet or shot travels. The barrel serves the purpose of providing direction and velocity to the bullet.
More correctly a "rifled slug" or "shotgun slug." An individual cylindrical projectile designed to be discharged from a shotgun. The term is often incorrectly used to mean a Bullet.
A process that increases the diameter of a workpiece by compressing its length.
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 person living in the State of Oregon that is a firm supporter of the Second Amendment (plus the other nine Bill of Rights amendments) and generally will also be a firearms enthusiast.

A steel bolt, mounted transversely through a rifle stock just under and behind the front (and sometimes rear) receiver ring,
sometimes concealed in the wood and usually against which the action is carefully bedded. When properly fitted, it helps distribute the recoil
and reinforces stock at the point where wood has been removed to accept the action. Recoil crossbolts can be recognized by the
flush-mounted circular steel fittings on the side of the stock, but are sometimes finished with contrasting wooden plugs and
sometimes concealed completely. Also called Reinforcing Crossbolt.
