The Glossary presented in this part of the website has been compiled by AFEMS’s Technical Committee on the base of its practical experience and intends to provide an operative support to the Member of the Association dealing with the proper definition of technical words in the most common EU languages.
It is not a comprehensive instrument, because it doesn’t cover the full range of terms used in our industry and the term’s definitions could be subject in the time to further change and refinement.
The Glossary doesn’t intend to provide any legal definition of the terms included.
A firearm that loads, locks and fires cartridges and ejects cartridges cases as long as the trigger is depressed and there are cartridges available in the feeding system (i.e. magazine or other such mechanism).
ACTION, POMPE - VORDERSCHAFTS-REPETIERER - MECANISMO DE CORREDERA PUMPING - MECCANISMO DI FUNZIONAMENTO A POMPA
A firearm, typically a shot gun, that features a movable forearm that is manually actuated to chamber a cartridge (mostly shot shell), extract and eject the cartridge case and put another cartridge in position to fire.
A firearm that loads, locks and fires cartridges and ejects cartridge cases in which each pull of the trigger results in a complete firing cycle, from firing through reloading. It is necessary that the trigger be released and pulled for each cycle.
That part of a firearm through which a projectile travels. The barrel may be rifled (i.e., with spiral grooves on the interior of the barrel) or smooth bore (i.e., a smooth interior barrel with no grooves, mostly for shot guns).
DIAMETRE DU CALIBRE - BOHRUNGSDURCHMESSER - DIAMETRO DEL CALIBRE - DIAMETRO INTERNO CANNA
On rifled barrels, the interior diameter of the barrel from the tops of the lands. On a smooth barrel, the interior dimension of the barrel forward of the chamber (not including the choke on shotgun barrels).
A projectile that may be used in military –or law enforcement rifles and handguns intended to pierce steel armour. For the use in rifles it is constructed mostly full jacketed and has a core constructed, from one or a combination of tungsten alloys, steel, iron or copper alloys. For the use in handguns it is often constructed as a solid non jacketed projectile from copper alloys.
A British military bullet developed in India the Dum-Dum Arsenal in 1897-98. It was a jacketed .303 calibre rifle bullet with the jacket nose left open to expose the lead core in hopes of greater effectiveness. Further development of the bullet was not pursued because the Hague Convention of 1899 outlawed such bullets for warfare.
A term used to designate the specific cartridge for which a firearm is chambered.
Metric – Units: It is the numerical term included the cartridge name (i.e. 7,62 x 51) to indicate a rough approximation of the bullet diameter and the case length in mm.
US – Units: It is the numerical term included in the cartridge name to indicate a rough approximation of the bullet diameter (i.e. .30 calibre - .308" diameter bullet).
The distribution of shot fired from a shotgun. Generally measured as a number or percentage of pellets striking in an outer circle of 750 mm and an inner circle of 375 mm. The shooting distance has to be determined according to sporting or hunting use.
The earliest type of propellant, allegedly made by the Chinese. First used for firearms in the 13th century, it is a mechanical mixture of potassium or sodium nitrate, charcoal, and sulphur. It makes a large cloud of smoke when fired.
A moving target, used for sport - or practice shooting with shotguns. A circular, domed frangible disc used as an aerial target for shotgun shooting games. Originally formed out of clay, modern targets are a combination of pitch and limestone. Dimensions and weights are regulated by trap and skeet shooting associations. They are often called "clay pigeons." (See also SKEET and SPORTING CLAYS)
BALL TRAP OU TIR SUR CIBLE LANCEE - TRAPSCHIESSEN - TIRO TRAP - TIRO TRAP
It is a sport in which shooters, using shotguns, fire at clay targets, which are launched by five different stations (three launchers or traps each station) which are located in a trench 15 m forward the firing line. (See TARGET CLAY and TRAP)
A slang term for a trigger requiring very low force to actuate. Note: Hair triggers are frequently used on competitive target rifles and pistols for increased accuracy. The reduced force needed to pull the trigger allows the shooter.
VERROU DE Détente - ABZUGSSICHERUNG - SEGURO DE DISPARO - SICURA AL CRILLETTO
An accessory for blocking a firearm from unauthorized use. Most trigger lock manufacturers advise against the use of a trigger lock on a loaded firearm, as shifting the lock against the trigger could fire the gun.
