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
A repeating firearm in which the ammunition is held in a multi-chambered cylinder, which is rotated to bring each chamber in line with
the barrel. Most revolvers are handguns, although shoulder-fired arms have been made using this sort of mechanism.
A firearm specially designed for use underwater.
A trigger that breaks (to release the hammer) easy.
The accumulation of unwanted material on solid surfaces. The fouling material can consist of either powder, lubrication residue, or bullet material such as lead or copper.
The ammount pressure needed (measured in pounds) for the trigger finger must put on the trigger before the gun will fire.
Trigger pull weight is measured by the number of pounds and ounces of pressure required to pull the trigger past the break.
A type of expanding bullet with a concavity in its nose to increase expansion on penetration of a solid target.
Some hollow-point's are also designed to fragment as they expand. They are least likely to
over-penetrate the target and harm an innocent bystander. Commonly used for self-defense.
In the Weaver stance,
the body is bladed partly sideways in relation to the target rather than squared towards it (think boxing or martial arts fighter stance).
The elbows are flexed and pointed downward. The strong-side arm is slightly straighter than the weak-side arm.
Even though the legs are not square to tharget, the hips should be square to the target. The feet should be pointed at the target.
The shooter pushes out with the gun hand, while the weak hand pulls back.
This produces a push-pull tension which is the chief defining characteristic of the Weaver stance.
The speed of a projectile or a load of shot at the point that it exits the muzzle of a firearm, normally expressed feet per second.
Anything that will safely stop a bullet and prevent it from hitting anything else after the target is struck.
A bullet that is designed to disintegrate into tiny particles upon impact to minimize their penetration for reasons of range safety,
to limit environmental impact, or to limit the danger behind the intended target. Examples are the Glaser Safety Slug and the breaching round.
