Whois & Analysis for rimfirecentral.com

Rimfire is a method of ignition for metallic firearm cartridges as well as the cartridges themselves.

It is called rimfire because the firing pin of a gun strikes and crushes the base's rim to ignite the primer.

The rim of the rimfire cartridge is essentially an extended and widened percussion cap which contains the priming compound, while the cartridge case itself contains the propellant powder and the projectile (bullet).

Once the rim of the cartridge has been struck and the bullet discharged, the cartridge cannot be reloaded, because the head has been deformed by the firing pin impact.

While many other different cartridge priming methods have been tried since the 19th century, only rimfire technology and centerfire technology survive today in significant use.

In guns, particularly firearms, caliber or calibre is the approximate internal diameter of the barrel, or the diameter of the projectile it fires, in hundredths or sometimes thousandths of an inch.

For example, a "45 caliber" firearm has a barrel diameter of.45 of an inch.

Barrel diameters can also be expressed using metric dimensions, as in "9mm pistol." When the barrel diameter is given in inches, the abbreviation "cal" (for "caliber") can be used.

For example, a small-bore rifle with a diameter of 0.22 inches can be referred to as.22 or a.22 cal; however, the decimal point is generally dropped when spoken, making it a "twenty-two caliber" or a "two-two caliber rifle".

A firearm is a portable gun - a barreled weapon that launches one or more projectiles, often driven by the action of an explosive force.

The first primitive firearms originated in 13th-century China when the one-person-portable fire lance was combined with projectiles.

The technology gradually spread through the rest of East Asia, South Asia, the Middle East and then into Europe.

Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants.

Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability.

Ammunition (noun, commonly shortened to ammo) is the general term used for the material fired, scattered, dropped or detonated from any weapon.

The term ammunition can be traced back to the mid 17th century.

Broadly speaking, ammunition refers to both expendable weapons (e.g. bombs, missiles, grenades, land mines, naval mines and anti-personnel mines) and the component parts of other weapons that create the effect on a target (e.g. bullets and warheads).

Nearly all weapons will require some form of ammunition to operate.

The word comes from the French la munition, which refers to the material used for war.

The terms ammunition and munitions are often used interchangeably, although the term munition now usually refers to both the actual weapons system alongside the ammunition required to operate it.
