The Definition of High Brass
By convention, powerfully loaded shotgun cartridges for hunting are generally manufactured with relatively longer brass end-caps than lower
powered cartridges intended for target shooting. While different-sized brass bases are of virtually no consequence to the strength of the
shell in relation to the steel breech of the gun itself, they do help the shooter identify the relative power of cartridges at a glance.
19 Other Firearms Definitions You Need To Know
The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF, BATF, and BATFE) is a federal law enforcement organization within the United States Department of Justice. Its responsibilities include the investigation and prevention of federal offenses involving the unlawful use, manufacture, and possession of firearms and explosives; acts of arson and bombings; and illegal trafficking of alcohol and tobacco products. The ATF also regulates via licensing the sale, possession, and transportation of firearms, ammunition, and explosives in interstate commerce. Many of ATF's activities are carried out in conjunction with task forces made up of state and local law enforcement officers, such as Project Safe Neighborhoods. ATF operates a unique fire research laboratory in Beltsville, Maryland, where full-scale mock-ups of criminal arson can be reconstructed.
An imaginary straight line from the eye through the sights of a firearm to the target.
A rifle stock, with a sculptured throughole at the wrist for the thumb, said to be more ergonometric to hold than a traditional stock.
Apart from being slower to mount, totally useless for a counter-dexterous person, it is so unmitigatedly graceless as to be beneath consideration.
A gun with more than one barrel, the most common being the double-barreled shotgun.
A small hole in the barrel of a gas-operated firearm through which expanding gases escape to power the autoloading system.
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.
Originally used to describe the spherical projectile used in black powder firearms,
now also used to refer to a fully jacketed bullet of cylindrical profile capped with a round nose
A firearm configuration where the magazine and action are behind the trigger.
This is the area in the barrel that is directly forward of the chamber, which tapers to the bore diameter.
An unexpected and undesirable discharge of a firearm caused by circumstances beyond the control of the participant(s) such as a mechanical failure or parts breakage.
There are very, very few firearms related "accidents" and if the "Three Rules" are followed there will hopefully be no injury.
Accidental Discharge should not be confused with "Negligent Discharge".
A two-barreled, side-by-side, shoulder-fired gun having one
smoothbore shotgun barrel and one rifled barrel.
The part in the breech mechanism that locks the action against the firing of the cartridge.
Any malfunction that results in no shot fired when the trigger is pulled. Commonly caused by a failure to feed, bad ammunition or a broken firing pin.
The area inside the bore nearest to the muzzle.
Abbreviation for Double Action Only. Is a type of firearm in which the firing mechanism cannot be cocked in a single-action stage. Firing always occurs as a double-action sequence where pulling the trigger both cocks and then fires the gun.
A trigger that breaks (to release the hammer) easy.
An armor-piercing shell must withstand the shock of punching through armor plating. Shells designed for this purpose
have a greatly strengthened case with a specially hardened and shaped nose,
and a much smaller bursting charge.
System of measurement for the internal bore diameter of a smooth-bore firearm based on the diameter of each of that
number of spherical lead balls whose total weight equals one pound.
The internal diameter of a 12 gauge shotgun barrel is therefore equal to the diameter of a lead
ball weighing 1/12 pound, which happens to be .729" (Or in British: Bore.) The Gauge/Bore system is also used, by convention, to describe the internal barrel diameter of large-bore,
19th century, English, single-shot and double-barrel rifles.
