Smoothbore firearms are guns that have a barrel without rifling, meaning the inside of the barrel is smooth. This design allows for the firing of various types of ammunition, including shotgun shells and cannonballs. Smoothbore firearms are often used for hunting and sport shooting, as they can effectively fire multiple projectiles at once. These firearms are typically less accurate than rifled guns at long distances, but they excel in close-range situations. Common examples of smoothbore firearms include shotguns and muskets. The versatility of smoothbore designs makes them popular for both recreational and military applications.
