Letter K Firearms Glossary
Usually referred to as a Kentucky Long Rifle or simply Longrifle, the Kentucky Rifle is a flintlock rifle with a long barrel and short, crooked stock. It is widely believed to be a largely unique development of American rifles that was uncommon in European rifles of the same period.
The Kentucky Long Rifleis an early example of a firearm using rifling, (spiral grooves in the bore). This gave the projectile, commonly a round lead ball, a spiraling motion, increasing the stability of the trajectory.
Rifled firearms saw their first major combat usage in the American colonies during the Seven Years war, and later the American Revolution in the eighteenth century.
A horizontal wedge, press-fit through the forend of a vintage gun, through a lump
attached to the underside of the barrel and out the other side of the forend.
To secure the forend in position. Also called a crosspin or a wedge fastener.
The tendency of a bullet to tip in flight and hit a target sideways, leaving a distinctly oblong hole.
This destabilization of the spinning bullet in flight is typically caused by a bullet weight inappropriate
for the rate of twist of the rifled barrel, an out-of-balance bullet or its having nicked an impediment such as a blade of grass, in flight.
The curved, forward end of the bar of a break-open firearm's action, about which the mounted
forend iron revolves downward. This area should be kept lightly greased to avoid galling the bearing surfaces.
A metal surface which contains a pattern of ridges or beads.
German for "short." Seen as part of a cartridge designation. On some German manufactured guns that use .380 ACP, the designated caliber is 9mm Kurtz (9mm Short), which is also the same as the Italian 9mm Corto
13 Other Firearms Definitions You Need To Know
An empty ammunition case.
A small metal explosive-filled cup which is placed over the nipple of a percussion firearm. As the cap is struck by the hammer, it explodes and sends a flame through the flashhole in the nipple to the main powder charge.
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.
The action of moving live cartridges from the magazine of a firearm into the chamber.
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 game of competitive clay pigeon shooting on a formally designed layout. In plan view, one launching machine is located 16 yards in front of a straight line,
firing rising targets perpendicular to and away from that line. Five competitors shoot five individual targets at each of five stations along that line.
Although each target is presented at slightly randomized vectors, trap emphasizes generally a single type of shot, outgoing and rising,
and targets are broken at generally longer ranges than Skeet.
A state of readiness of a firearm. The hammer (or similar mechanism if there is no hammer) only needs to be released by the trigger to cause the gun to fire.
A type of firearm in which the action is closed, with a cartridge in the chamber prior to firing. When the trigger is pressed the cartridge is fired,
and the action cycles loading another cartridge into chamber and when firing is stopped the bolt remains closed and the chamber remains loaded.
Co-Witness Sighting is the use of any iron sight mounted onto a rifle that is fitted with an optical sight as a primary sighting system.
They come in two basic configurations, fixed or flip-up. The idea is that if you align your red dot and your iron
sights you have a backup aiming system on the gun.
The tapered rear end of a bullet. This design is used to increase ballistic efficiency at long range.
In the Modern Isosceles
the feet are roughly shoulder width apart, with the gun-side foot closer to the target than the off-side foot.
The knees are flexed, and the entire body leans slightly toward the target. The shoulders are closer to the target than the hips, and the hips are more forward than the knees.
The shoulders are rotated forward and the head, rather than being upright, is vultured down behind the sights.
The entire body thus has an aggressively forward appearance, and is poised to move quickly if necessary.
