The Definition of Casehardening
A heat-treating process that incorporates carbon into the surface molecular
structure of the steel, providing a hard-wearing surface without making the entire
receiver brittle. The parts to be casehardened are packed in a crucible with
carbon-rich media such as bone meal and charcoal, heated to bright orange, about
1800°F, then quenched in bubbling oil. Also

Helical grooves in the barrel of a gun or firearm, which imparts a spin to a projectile around its long axis.
This spin serves to gyroscopically stabilize the projectile, improving its aerodynamic stability and accuracy.
A firing pin which moves freely forward and backward in the breechblock.
Originally, live pigeons were used as targets, but they were gradually replaced with clay disks and ultimately banned. Later clay has been replaced with more suitable raw materials.
Also spelled Forend.
That part of the stock forward of the action and located below the barrel or barrels.
It is designed to give the shooter a place to hold the front end of the gun and protects the shooter's hand from getting burned on the hot barrel.
The NRA teaches the Three Basic Rules of Safe Gun Handling.
There are additional rules, but these are the three that if any two are followed, nobody will be hurt. However, obviously, all three should
always be followed.
Rule One: ALWAYS keep the gun pointed in a safe direction.
The NRA established these three rules in 1871. They were created to be easy to understand and remember,
ensuring the highest possible level of firearm safety.
Rule Two: ALWAYS keep your finger off the trigger until ready to shoot.
Rule Three: ALWAYS keep the gun unloaded until ready to use.

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.
On a revolver, the collective ejector, manually operated through the center of an opened cylinder, when activated, clears all chambers at once.
Protective plates, usually of steel or horn, covering the top and bottom of a gunstock's butt only (the heel and the toe); leaving wood exposed in the center
A type of expanding bullet with a concavity in its nose to increase expansion on penetration of a solid target.
Some hollow-point's are also designed to fragment as they expand. They are least likely to
over-penetrate the target and harm an innocent bystander. Commonly used for self-defense.
A firearm that can be separated into (at least) two subassemblies in order to make a shorter package than when put together, without tools.
There is no specific requirement regarding how this disassembly must be accomplished; the mechanical design is up to the creativity of the maker.
This arrangement allows for more convenient transportation of a firearm, but with rifles, where the action normally separates from the barrel, usually at a small sacrifice in accuracy.
Takedown firearms can also be called take-apart firearms.
Good examples of a takedown guns are the Henry AR-7 Survival Rifle, the Ruger 10/22 Takedown or the TNW Aero.
A popular but imprecise term used to refer to the ability of a small arms cartridge to cause a human assailant or an animal to be immediately incapacitated when shot with it. A more precise term is be Wound Trauma Incapacitation (WTI).
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 correct technical term for the ability of a projectile to incapacitate an animal or human shot with a firearm. Incorrectly called Stopping Power.
Incorrectoly sometimes referred to as a silencer, it is used to reduce the sound of a firearm's discharge.
They do not actually silence most firearms but rather lower the intensity of the muzzle blast and change the sound characteristics
(works similarly to an automotive muffler by disrupting and spreading out the sound waves).
The possession, use, and transportation of silencers have been tightly controlled under federal law since 1934.
Any device which reduces the sound of discharge by more than 2 dB is considered by the BATF to be a suppressor.
The charge used to ignite the propelling charge.
The process of a bullet expanding under pressure to fit the bore of the firearm, or a cartridge case expanding under pressure to seal the chamber.
