The Definition of Hang Fire
An unexpected delay between the triggering of a firearm and the ignition of the propellant.
This failure was common in firearm actions that relied on open primer pans, due to the poor or inconsistent quality of the powder.
Modern weapons are susceptible, particularly if the ammunition has been stored in an environment outside of the design specifications.
Reloaded ammunition may also be the cause if not reloaded properly
19 Other Firearms Definitions You Need To Know
The action of moving live cartridges from the magazine of a firearm into the chamber.
A pocketed belt for holding ammunition and cartridges. It was usually slung over the chest.
Bandoliers are now rare because most military arms use magazines which are not well-suited to being stored in such a manner.
They are, however, still commonly used with shotguns, as individual 12 gauge shells can easily be stored in traditionally designed bandoliers.
A trigger that doesn't have to travel very far before it reaches the break. In a 1911 semi-auto pistol, a short trigger is a different part than a long trigger,
and (in addition to providing less motion) it features a shorter reach which may be of benefit to a small-handed shooter.
Smith & Wesson term for a revolver grip design introduced in the 1930s where the top of the grip extends higher than it had in earlier configurations, to provide a more comfortable hold.
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.
A type of gas operation for a firearm that directs gas from a fired cartridge directly to the bolt carrier or slide assembly to cycle the action.
An air gun that shoots a skirted pellet.
German for Hand-Cocking or Cocker/De-Cocker. A type of action on a break-open gun or rifle where, in place of a traditional top tang safety,
a somewhat more robust tab is fitted. Normally such a gun is carried in the field loaded, but with the action not cocked,
an exceedingly safe condition. Then, when ready to fire, the shooter, instead of pushing a safety tab forward,
pushes this larger tab forward, cocking the mainspring, making the gun ready to fire.
Then, if the shot is not taken, he may simply slide this tab rearwards again, de-cocking the gun
and returning it to the still-loaded, but very safe position.
A specialized firearm used underwater that is fired when in direct contact with the target.
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
An opening. The ejection port is the opening in the side of a semi-auto from which spent cases are ejected.
A bullet design featuring a conical extended nose, with a flat point, and a sharp edged shoulder that serves to cut a full diameter hole in the target.
This design also may be found with a hollow point to facilitate expansion. A modified wadcutter bullet design with slightly sloping edges, designed to load smoothly in a semi-automatic pistol.
The tendency of a firearm when fired to move backwards, and a little upwards as a reaction to the force of the projectile moving down the barrel.
As Newton says, to every action there is always an equal and opposite reaction. The mass of the firearm provides some inertia to counteract the momentum of recoil.
What remains is absorbed by at the shoulder or the hand. The heavier the gun, the less the recoil. The more powerful the cartridge, the more the recoil.
The stock is the wooden, polymer, or metal handle of a long gun that extends from the trigger back to where the gun is braced against the shoulder.
An adjustable stock is one that can be easily lengthened or shortened to fit shooters of different sizes.
The upper portion of a semi-automatic pistol that houses the barrel and contains the breechblock and portions of the firing mechanism.
Ejecting the spent case as it moves to the rear and loading a fresh cartridge into the chamber as it moves forward again.
As its name states, it slides along tracks in the top of the frame during the recoil process providing the linkage between
the breechblock and barrel.
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.
The opening through which the empty, spent ammunition case is ejected from of a firearm.
To tilt a gun to one side or the other,
complicating sighting considerably. Can cause material loss of accuracy,
particularly with a rifle at longer ranges. Some better long range target rifles
are equipped with Spirit Level sights
to help control canting.
A device, incorporated into the design of most firearms actions that, when engaged, should prevent the discharge of the firearm.
Some safeties are more positive than others. A safety device is not a perfect substitute for the general principles
of responsible gun handling. Never point a gun in a direction you do not intend to shoot
