A semi-automatic shotgun is a type of firearm that automatically reloads after each shot, allowing the shooter to fire multiple rounds without manually cycling the action. This mechanism uses the energy from the fired shell to eject the spent cartridge and chamber a new one, making it faster than a pump-action shotgun. These shotguns are popular for various uses, including hunting and sport shooting. They can accommodate different types of ammunition, such as birdshot, buckshot, and slugs, providing versatility for different shooting scenarios. Semi-automatic shotguns are often favored for their ease of use and rapid follow-up shots.
