The Definition of Spotter
The spotter is a helper who gives the shooter guidance on how to hit a particular target.
In some cases the spotter may just report the location of the bullet impact. In other cases they may judge the speed and direction of
the wind, determine the range, and give the shooter the settings to be used on the sights.

A box of ammunition roughly equal in size and weight to a brick. Most often used to describe a 500-round container of .22 Long Rifle ammunition.
The point of the trigger's return at which the gun's internal mechanisms are ready to fire another round.
A family of smokeless propellants developed and produced in the United Kingdom from 1889 to
replace gunpowder as a military propellant. Like gunpowder, cordite is classified as a low
explosive because of its slow burning rates and consequently low brisance.
The hot gases produced by burning gunpowder or cordite generate sufficient pressure to propel a bullet or shell to its target,
but not enough to destroy the barrel of the firearm, or gun.
A misfeed or other failure to fire which can be cleared on the spot and without tools.
A small hole in the barrel of a gas-operated firearm through which expanding gases escape to power the autoloading system.
A popular but imprecise term used to refer to the ability of a small arms cartridge to cause a human assailant or an animal to be immediately incapacitated when shot with it. A more precise term is be Wound Trauma Incapacitation (WTI).
Round knob, semi pistol grip.
A Muzzleloading long gun which has a completely smooth bore and is intended to fire a single projectile rather than a collection of shot.
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.
The four rules of firearms safety,were originally introduced in the early 1900's by various shooting education sources (with varying phrasing, but same implications), they apply every single time a firearm is handled in any way or for any reason. The NRA
teaches the Three Rules of Safe Gun Handling.
Rule One: All guns are always loaded. (Treat all guns as if they are loaded, no matter what!)
Rule Two: Never point your firearm at anything you are not willing to destroy.
Rule Three: Never put your finger on the trigger unless your sights are on target (and you have made the decision to fire).
Rule Four: Be sure of your target and what is behind it.
A long strip of leather, plastic, or nylon which is fastened at the fore and rear of the gun for the easy carry of long guns.
A bullet designed to expand on impact, increasing in diameter to limit penetration and/or produce a larger diameter wound.
The two typical designs are the hollow point bullet and the soft point bullet. Expanding bullets were given the name Dum-dum, or dumdum,
after an early British example produced in the Dum Dum Arsenal, near Calcutta, India by Captain Neville Bertie-Clay in the the mid-1870s.
Modern sef-defensive, JHP (Jacketed Hollow Point), ammunition are based on the original dum-dum ammunition design and principles.
A common type of iron sights in which the rear sight is an open-topped U or a V or a square-notch shape and with a
blade type front sight, in contrast to the closed circle commonly found in aperture sights.
A military person designated as a special marksman who is used to shoot designated targets of opportunity at long range.
An oversized, lightweight housing that allows a sub-calibre projectile to be fired in a larger-diameter bore, usually in the interest of increased velocity.
The sabot falls away from the actual projectile upon exiting the muzzle.
For example, a hunter could use his .30-30 deer rifle to shoot small game with .22 centerfire bullets.
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.
The bevelled portion of the rifling at the rear end of the barrel (and the forward portion of the chamber) where the bullet first engages the lands.
