Chamber (firearms)
In firearms, the chamber is the cavity at the back end of a breechloader's gun barrel, barrel or cylinder (firearms), cylinder, where the cartridge (firearms), cartridge is inserted before being fired. The rear opening of the chamber is the breech, and is sealed by the breechblock or the bolt (firearms), bolt. Function Rifles and pistols generally have a single chamber integral to their barrels, but revolvers have multiple chambers in their cylinder, and no chamber in their barrel. Thus, rifles and pistols can usually still be fired with the magazine (firearms), magazine removed as long as a Cartridge (firearms), cartridge is inserted into the chamber, while a revolver cannot be fired at all with its cylinder cylinder (firearms)#Swing out cylinder, swung out. The act of ''chambering'' a cartridge means the insertion of a round into the chamber, either manually or through the firearm action, action of the weapon, e.g., pump-action, lever-action, bolt action, or Firearm action#A ...

Automated Firearms Identification
Automated Firearms Identification refers to the use of computers to automate the process of matching a piece of recovered ballistic fingerprinting, ballistic evidence (which can be either bullets or cartridge cases, or fragments thereof), against a database. Automated ballistic identification systems Every firearm leaves unique, reproducible markings on expended (used) bullet and cartridge cases that it fired. The barrel, firing pin, firing chamber, extractor, ejector and other parts of the gun leave these marks, called toolmarks, on the bullet and cartridge case faces. Individually and collectively, these markings function as the “ballistic signature” of the firearm. Traditional firearms identification involves the use of a Comparison Microscope. A firearms examiner visually compares the ballistic signature of a bullet/cartridge recovered from a crime scene with those in the police files. This process and its outcome, while accurate and acceptable in court, is extremely time ...

Shooting
Shooting is the act or process of discharging a projectile from a ranged weapon (such as a gun, bow and arrow, bow, crossbow, slingshot, or blowgun, blowpipe). Even the acts of launching flamethrower, flame, artillery, dart (missile), darts, harpoons, grenades, rockets, and guided missiles can be considered acts of shooting. When using a firearm, the act of shooting is often called firing as it involves initiating a combustion (deflagration) of chemical propellants. Shooting can take place in a shooting range or in the field, in shooting sports, hunting or in combat. The person involved in the shooting activity is called a shooter. A skilled, accurate shooter is a ''marksman'' or ''sharpshooter'', and a person's level of shooting proficiency is referred to as their ''marksmanship''. Competitive shooting Shooting has inspired competition, and in several countries rifle clubs started to form in the 19th century. Soon international shooting events evolved, including Shooting ...

Forensic Firearm Examination
Forensic firearm examination is the forensic process of examining the characteristics of firearms or bullets left behind at a crime scene. Specialists in this field are tasked with linking bullets to weapons and weapons to individuals. Obliterated serial numbers can be raised and recorded in an attempt to find the registered owner of the weapon. Nitric acid (HNO3) is the most common reagent used for this. Examiners can also look for fingerprints on the weapon and cartridges. Fingerprints are key pieces of evidence. If crime scene investigators find prints at a scene, they will be dusted, photographed, collected, and analyzed both by hand (using comparison microscopes) as well as compared to databases for potential references. By examining unique striations, scratches left behind on the bullet and weapon, individual fired rounds can be, but not always are, linked back to a specific weapon. These striations are due to the rifling inside the barrels of firearms. Rifling spins the b ...

45 ACP
The .45 ACP (Automatic Colt Pistol) or .45 Auto (11.43×23mm) is a Rim (firearms)#Rimless, rimless straight-walled handgun Cartridge (firearms), cartridge designed by John Moses Browning in 1904, for use in his prototype Colt's Manufacturing Company, Colt semi-automatic pistol. After successful military trials, it was adopted as the standard chambering for Colt's M1911 pistol. The round was developed due to a lack of stopping power in Sulu experienced in the Moro Rebellion using the .38 Long Colt. This experience and the Thompson–LaGarde Tests of 1904 led the Army and the Cavalry to decide a minimum of .45 caliber was required in a new handgun. The standard issue military .45 ACP round has a 230-Grain (unit), grain bullet that travels at approximately 830 feet per second when fired from the government issue M1911A1 pistol. It operates at a relatively low maximum chamber pressure rating of , compared to for both 9×19mm Parabellum, 9mm Parabellum and .40 S&W, which due to a lo ...
