A bolt-action is a type of firearm mechanism that requires the shooter to manually operate a bolt to load and eject cartridges. This design allows for precise shooting, as the action is typically more stable than semi-automatic systems. Bolt-action rifles are commonly used in hunting and target shooting due to their accuracy and reliability. The mechanism consists of a handle that the shooter lifts and pulls back to open the chamber, allowing for a new cartridge to be inserted. Once the bolt is pushed forward and locked, the rifle is ready to fire. Popular examples of bolt-action rifles include the Remington 700 and Mauser 98.
