The Definition of Fouling Shot
A fouling shot is a shot fired through a clean bore, intended to leave some residue of firing and prepare the bore for more consistent performance in subsequent shots.
The first shot through a clean bore will behave differently from subsequent shots through a bore with traces of powder residue, resulting in a different point of impact.
19 Other Firearms Definitions You Need To Know
An established place where firearms and ammunition are stored, repaired, or manufactured.
The term is misused by the media to mean more than one firearm or any quantity of ammunition, as in "they found an arsenal."
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 spring-loaded hinged front trigger on a dual trigger side by side or over under shotgun, built to cushion its impact on one's trigger finger as the gun recoils when the rear trigger is pulled.
A malfunction in which the spent case fails to eject from a semi-automatic firearm and blocks the chamber.
As the fresh round is brought forward it cannot enter the chamber. It is cleared by
stripping the magazine from the gun, racking the slide several times to eject the spent case, and then reloading.
The setting on the sights of a firearm that controls the vertical placement and the altitude above mean sea level.
This is important for long range precision shooting because the air density changes with elevation and affects the path of the bullet.
Defined according to Section 921 (a) (16), Title 18, U.S.C. as:
A. any firearm (including any firearm with matchlock, flintlock, percussion cap, or similar type of ignition system) manufactured in or before 1898; and
B. any replica of any firearm described in subparagraph (A) if such replica (i) is not designed or redesigned for using rimfire or conventional centerfire fixed ammunition, or (ii)
uses rimfire or conventional centerfire fixed ammunition which is no longer manufactured in the United States and which is not readily available in the ordinary channels of commercial trade.
Typically used in the .22 caliber cartridge designation .22 Long Rifle, which is abbreviated .22LR.
The four rules of firearms safety,were originally introduced in the early 1900's by various shooting education sources (with varying phrasing, but same implications), they apply every single time a firearm is handled in any way or for any reason. The NRA
teaches the Three Rules of Safe Gun Handling.
Rule One: All guns are always loaded. (Treat all guns as if they are loaded, no matter what!)
Rule Two: Never point your firearm at anything you are not willing to destroy.
Rule Three: Never put your finger on the trigger unless your sights are on target (and you have made the decision to fire).
Rule Four: Be sure of your target and what is behind it.
A concept created by eminent gun writer Col. Jeff Cooper. A scout rifle, generally, is a bolt action carbine firing a
medium power round suitable for taking large game (e.g., .308), fitted with a long eye-relief telescopic sight mounted on the barrel, and a back up set of iron sights.
Some triggers can be pulled slightly backwards before the shooter can feel any tension and before
the hammer or striker begins to retract. Pre-travel is any movement of the trigger that begins before the trigger starts to engage.
Synonymous with pistol. A small, short-barreled firearm designed to be fired while held in one or both hands, possibly small enough to be concealed on the person, rather than while braced against the shoulder. The term includes antique dueling pistols, modern single-shot, semi-automatic pistols and revolvers.
A device fitted inside the buttstock of a heavily-recoiling gun or rifle, usually containing mercury and a valve. As the gun recoils,
the mercury is displaced temporarily, increasing the duration, and thus diminishing the perceived impact of the recoil.
The added half-pound of weight doesn#39;t hurt either.
From the Latin for "more."
A term indicating a relatively heavily loaded metallic cartridge or shotshell and a gun safely constructed to fire it.
It generally indicates a round which cannot be interchanged with other loadings of the same caliber (for example, a .22 Magnum shell does not fit within a firearm designed to fire .22 Long Rifle ammunition).
A safety catch fitted to a hammer gun where a sliding bar moves into a slot in the inner wall of the hammer base, locking it in place in the cocked position.
The safety can then be released silently by sliding the tab, avoiding the game-startling sound of the hammer cocking.
The paper filler at the rear of the powder charge of the shotgun shell.
The speed at which a projectile travels. Velocity is usually measured in feet per second or metres per second.
An inert ammunition-shaped object, used in practice to simulate misfeeds and other malfunctions and also used in dry fire practice.
Unlike a blank, a dummy round contains no charge at all.
A snap-cap is a type of dummy round.
If the trigger is able to continue moving to the rear after the shot has fired, the trigger is said to over-travel.
Anything a person can hide behind that will probably stopp a bullet.
