Spiral grooves formed into the bore of a gun barrel, which cause the bullet to spin upon firing, thus stabilizing it much like a thrown football.
Rifling may be cut, swaged, or forged into the barrel.
An offset of a gun stock to the left, so
that the line of sight aligns comfortably with the left eye while the butt of the stock
rests comfortably on the left shoulder. Almost all left-handed shooters benefit from a
little caston and most custom built guns are made this way. The only question is how
much. The caston of a gun is about right when, with the gun comfortably mounted, the
front bead lines up with the center of the standing breech.
A stock offset to the right, for shooting from the right shoulder is said to be
A type of shotgun ammunition which uses very small pellets with individual projectiles of less than .24" in diameter
designed to be discharged in quantity from the shotgun. The size of the shot is given as a number or letter--
with the larger number the smaller the shot size. It is so named because it is most often used for hunting birds.
The finest size generally used is #9 which is approximately .08" in diameter and the largest common size is #2 which is approximately .15"
Also spelled "+P" or "P+".
Is small arms ammunition that has been loaded to a higher internal pressure than standard for it's caliber.
Many calibers are available in both standard and +p or +p+ variants. Ammunition marked +p produces more power
and higher pressures than the standard ammunition. Not all firearms are designed to handle the increased
pressure consult your owner's manual or gun manufacturer before using +P ammunition.
The original small single-shot or multi-barreled pocket pistol designed and manufactured by Henry Deringer of Philadelphia.
Derringers (spelled with two Rs) are called that because of the original desinger and anmufactuturer of that
type of gun, Henry Deringer. To get around copyright infringment other designers and manufacturers spell the name with two Rs.

A pair of slender and easily-carried wooden dowels or sticks, which when held, crossed, in the fingers of the left hand while also supporting the forend of a rifle,
usually shooting offhand, provides somewhat enhanced stability for a more accurate shot.
An imaginary line which runs right down the center of the handgun's barrel and out though the back end of the gun.
A handgun may have a high bore axis, with the imaginary line running out into space well above the shooter's hand.
Or it may have a low bore axis, with the imaginary line running either straight through the shooter's hand or
just skimming the surface slightly above her hand. A high bore axis tends to create greater perceived recoil
and more muzzle flip when firing the gun than does a low bore axis.
A type of firearm action which uses a lever located around the trigger guard area,
(often including the trigger guard itself) to load fresh cartridges into the chamber of the barrel when the lever is worked.
