19 Other Firearms Definitions You Need To Know


Shotgun Shell

The cartridge for a shotgun. It is also called a "shell," and its body is usually made of plastic (metal shotgun shells are very rare, paper shotgun shells are extinct) with a metal head. Small shotshells are also made for rifles and handguns and are often used for vermin control.

Striker

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.

Igniting Charge

The charge used to ignite the propelling charge.

CQB

Abbreviation for Close Quarters Battle.

Misfire

The condition of a cartridge not firing when an attempt to fire it is made. It can be caused by either a defective cartridge or a defective firearm. The term is frequently misused to indicate a Negligent Discharge of a firearm.

Holdopen Toplever

A catch built into the receiver of a break-open gun to keep the toplever in its extreme right position when the barrels are removed. This device makes it slightly easier to remount the barrels. As the barrels are mounted and the breech closed, the barrels contact some kind of release pin (marked with the arrow) and the toplever automatically returns to the center locked position. Because, however, it requires a separate act to find and to depress this tiny tab to re-center the toplever on a broken-down gun, this feature may be irritating when trying to put a gun away in its case.

Monte Carlo Stock

A rifle or shotgun stock that has a Monte Carlo style comb

Second Amendment

The second article in the United States Bill of Rights which states, "A well regulated militia being necessary for a free state, the right of the people to keep and bear arms shall not be infringed."

WCF

Abbreviation for Winchester Centerfire.

Stutzen

German for a short rifle or carbine.

Shoulder

To bring the butt of a long gun's stock to the shooter's shoulder, preparatory to firing the gun.

Autoloader

A firearm that automatically loads the next cartridge to be fired into the chamber either upon the pull of the trigger in an open bolt design or upon the firing of the previous round in a close bolt design.
Autoloader should not be confused with Automatic or Semi-Automatic since the term Autoloader only applies to how the next round is chambered not how many rounds can be fired per trigger pull. All Automatic and Semi-Automatic firearms are autoloaders. Revolvers, bolt action, lever action and pump action firearms are not autoloaders.

Terminal Ballistics

A sub-field of ballistics, is the study of the behavior of a projectile when it hits its target.

WC

Abbreviation for wadcutter.

Varmint Gun

Usually a rifle, but not always. A small-caliber firearm or high-powered air gun primarily used for hunting non-native or non-game animals such as rats, squirrels, gophers, jackrabbits, marmots, groundhogs, porcupine, opossum, coyote, skunks, weasels, and other animals considered to be nuisance vermin destructive to native or domestic plants and animals.

Range Finder

A device used to determine the range to a target. Many range finders work by bouncing a laser beam off the target or nearby object and measuring the time for the reflection to arrive back at the instrument. It is also possible to use various passive optical devices such as a mil-dot telescopic sight.

Creep

Sloppy movement (slack) of a trigger before the actual point of let-off.

Hand-Detachable Locks

The firing mechanism of a break-open gun which may be removed for inspection or cleaning without the use of tools. The release latch may be plainly visible or concealed. A feature typically seen on sidelock guns but also on the Westley Richards "droplock" boxlock action.
