Repeater
An action fed from a magazine so successive rounds can be chambered and fired without loading each one by hand.
A repeater is any rifle whose action draws fresh cartridges from a magazine, letting the shooter chamber and fire several rounds before reloading. As the bolt cycles, it strips the top round off the stack and feeds it into the chamber, so the shooter never has to place each cartridge by hand. This is the standard arrangement for virtually every field, hunting, and tactical bolt gun.
The repeating design trades a little receiver rigidity for a decisive gain in speed and follow-up capability, which matters in timed precision matches and any situation needing a quick second shot. Modern precision repeaters usually feed from a detachable box magazine, so empty mags swap out fast and the rifle returns to action quickly. The contrast is the single-shot, which loads one round at a time for maximum stiffness.
