This is the Urban Shooter WIKI.

After I learn how to do it better, or enlist of the help of Urban Shooter supporters that have the know how— I expect this to work/look a whole lot better.

Until then, “Don’t Tase Me, Bro; this is just one brothers attempt at a WIKI.

ACCURIZE To modify, rework, and refine a weapon to improve the characteristics of the designed function and accuracy capabilities.

ACP Automatic Colt Pistol cartridge.

ACTION The part to which the barrel is attached. In a rifle it is often called the receiver. Shotgun or double-barreled sections house all the mechanisms or working parts. The term may be further modified as side action, breech-action, belt-action, snap-section, etc. It is also used to indicate the different forms of charging the weapon as bolt-action, lever-action, pump action, etc.

ADJUSTABLE TRIGGER One that can be adjusted for weight of pull. Aperture sight front of a rear sight, primarily for a rifle, with a circular opening in the center. Interchangeable discs with holes of varying diameters may be inserted to control the sight picture according to shooting conditions.

AUTO LOADING A type of arm in which the force of the explosion of the first shot is used to unlock the mechanism, extract or eject the empty shell, and to reload by stripping and feeding another cartridge from the magazine into the chamber. The trigger must be pressed for each successive shot.

AUTOMATIC WEAPON a firearm in which the force of the explosion of the first shot is used to continue the operation of unlocking, extraction, ejection, reloading, locking, and firing continuously, as long as the ammunition lasts in the magazine, belt, or strip, the pressure on the trigger is continued. The name is commonly applied erroneously to auto loading, repeating hand firearms. I.E., One pull of the trigger initiates the entire emptying of the magazine.

BACK STRAP The rear extension of a pistol or revolver frame that curves downward between the grips.

BALL Round lead ball used as a bullet in most muzzle loading rifles
and pistols.

BALL SCREW Used in muzzle loading, this looks like a wood screw. It threads into the end of the ramrod. It can be twisted into the soft lead ball when it is inside the barrel. Then the ball can be pulled backwards to unload the rifle when it has been fired.

B.A.R. Abbreviation for Browning Automatic Rifle, a gas-operated
military weapon invented by John M. Browning (1855-1926).

BARREL Metal tube containing the chamber and bore of a firearm.

BARREL LENGTH The distance between the muzzle and the rear face, breech, of the barrel where it abuts the breech bold or bolt, thus including the chamber. Revolver barrel lengths do not include the chamber, their chambers being in the cylinder. The design of a barrel length takes into account the burning rate of the propellant powder to be used and the projectile to be fired.

BARREL LUG A projection integral with the barrel used to secure the magazine, forearm, or some moveable part to the barrel.

BEAD A small snob of metal on a firearm near the muzzle used for a front sight in aiming.

BENCH REST A specially constructed shooting bench at which the shooter sits to support his elbow and the gun barrel. Benchrest shooting is concerned with firing groups as small as possible at a target over measured distances and with any type of rifle and cartridge best adapted for super accurate performance.

BIATHLON An event combining a cross-country race on skis and firing a rifle at various distances. This was even included in the 1960 Olympic Winter Games.

BINOCULAR VISION Sighting with both eyes open.

BIPOD A two-legged stand or mount; i.e., a stand for a spotting scope or the mount for a mortar or an automatic weapon.

BLOW BACK (1) Escape, to the rear and under pressure, of gases formed during the firing of the gun. May be caused by a defective breech mechanism, a ruptured cartridge, case, or a faulty primer. (2) Type of weapon operation in which the force of expanding gases acting to the rear against the face of the bolt furnishes all the energy required to initiate the complete cycle of operations of the gun. A weapon, which employs this method of operation, is characterized by the absence of any breech lock or bolt lock mechanism.

BLOW FORWARD A type of automatic action in which the barrel is blown forward then returns against the standing breech by spring pull, reloading and taking place during the return movement.

BLUING Purposely rusting metal by artificial oxidation to form a protective coating.

BOLT A sliding mechanism that closes the breech in some types of extractors and firing pins and supports the base of the cartridge case.

BOLT ACTION A rifle and shotgun mechanism whereby the breech is opened and closed by a manually operated bolt which travels back and forth in the receiver in a direct line with chamber and barrel. 1. Turning bolt—locking lugs turned to lock the action. 2. Straight pull—locking lugs actuated by bolt studs, which slide in grooves cut into the bolt cylinder.

BOLT FACE That portion of the bolt that engages and supports the head of the cartridge.

BORE (1) The interior of the barrel through which the charge or bullet passes. (2) The diameter measured from land to land.

BULLET GAUGE Gauges normally used to measure the diameter and concentricity of a bullet.

BUTT The shoulder end of a gun stock; the bottom of a revolver or pistol grip. Loosely used to indicate the complete butt stock of rifles and shotguns or the grip of a handgun.

BUTT PLATE A metal, plastic, or rubber covering for the rear edges of a gunstock; usually corrugated to prevent slipping from the shoulder. On some rifles, butt plates are usually adjustable for vertical movement and may have extension prongs, which
fit under and/or over the shoulder.

CALIBER Bore diameter of a rifle or handgun measured from one land to the opposite land, or the diameter before rifling, designated in fractions of an inch or millimeters, although a stated caliber may not be an exact figure. Black powder calibers, such as .45-70-405, means .45″”diameter, 70 as the weight of the powder charge, and 405 as the weight of the bullet in grams; many of these old designations were incorporated into modern smokeless powder nomenclature, but the second figure is meaningless. Designations such as .250-3000 refer to caliber and muzzle velocity; 8 mm. X 56 refers to caliber and length in millimeters.

CAM A rotating or sliding projection that either imparts to or receives a motion from a counteracting part, such as roller, pin, etc. Thus, a camming action.

CENTIMETER 1/100 of a meter, or 0.3937 inch.

CHAMBER The compartment at the rear of a gun barrel that holds a charge or cartridge one of the compartments in the cylinder of a revolver. Also the action of inserting a round of ammunition in the chamber or a firearm.

CHAMFER To bevel. Chamfering a cartridge case means beveling the inside of it’s by cutting or rolling the edge.
CHARGER Any container used in muzzle end of a shotgun barrel that controls the shot pattern; the difference between bore and parallel diameters, expressed in thousandths of an inch, or points. The wider the pattern desired, the less the amount of choke required. Degree of choke is measured by approximate percentage of pellets striking within a 30” circle at forty yards.

CHOKE Constriction at the muzzle end of a shotgun barrel which controls the shot pattern; the difference between bore and parallel diameters, expressed in thousandths of an inch, or points. The wider the pattern desired, the less the amount of choke required. Degree of choke is measured by approximate percentage of pellets striking within a 30” circle at forty yards.

CHRONOGRAPH An electric or electronic device for recording a projectile’s time of flight from which velocities are computed.

CLIP (Most misused term in the shooting world-authors note). 1. Cartridge clip—open top and bottom metal container for cartridges that is pressed into the magazine well. Cartridges are fed from it into the chamber by the loading mechanism; automatic ejection of the clip follows feeding of the last cartridge. 2. Mannlicher clip—Mauser-type clip or charger is a metal band which holds the cartridge for stripping into the magazine from the top by manual pressure. This type of clip does not remain in the magazine but is either removed before firing or ejected by the closing of the bolt.

COCK (the verb not the noun) To draw the hammer or cocking piece back into firing position either manually or by pressure on the trigger; also, to top set the trigger for firing. In a half cock position, the hammer or cocking piece is partially retraced but mechanically prevented from contacting the firing pin.

COMPENSATOR A device used on the barrel of a weapon to reduce recoil.

CROSS BOLT A movable, locking bar at right angles to the bore, which either locks or strengthens the locking mechanism of a closed breech, usually that of a break-type shot-gun. Some bolt action guns may use a cross bolt to lock the bolt in an open position.

CYLINDER (1.) True diameter of the bore of a shotgun barrel, hence without any degree of choke. Delivers a 25% to 35% shot charge pattern. See choke. 2. A round steel block, the inside of which is bored with multiple chambers for cartridges. Used as the loading device for revolvers; formerly in some types of rifles—notable Colt.

DECIBEL A unit of measure used in evaluation sound levels. Measurement is made by a sound level meter. Example: sound in a quiet business office is about forty decibels; average street traffic one hundred feet away is from sixty to seventy decibels; a gunshot registers about one hundred decibels; and a boiler shop is about one hundred and thirty decibels, just below the limit of endurance of the human ear.

DOUBLE ACTION That type of firing action whereby a single pull of the trigger both cocks and fires the weapon. It is employed in revolvers and old types of rifles and shotguns. It contrasts with single action, which requires the hammer to be cocked by hand prior to firing by pulling the trigger. See single action.
