Aself-loading rifleorautoloading rifle is a rifle with an action using a portion of the energy of each cartridge fired to load another cartridge. Self-loading pistols are similar, but intended to be held and fired by a single hand, while rifles are designed to be held with both hands and fired from the shoulder.[1]
Early breech-loading firearms were single-shot devices holding a single cartridge. When that cartridge had been fired, the person using the firearm would remove the empty cartridge, find another cartridge from a pocket or other carrying apparatus, and load that cartridge into the firearm chamber before another shot could be fired. Later repeating rifles and pistols were equipped with a magazine holding several cartridges with a spring to push those cartridges into position to be loaded by manually operating the action of the firearm—as by a lever, bolt, or pump mechanism—thus avoiding the procedure of locating and manually positioning each new cartridge. Later first developed in the early 1900s[2] self-loading firearms avoid manual operation of the action by using energy of the cartridge being fired to operate the action, so the shooter may fire additional cartridges without manually operating the firearm action until the magazine is empty.[3]
