A rifled gun is a type of firearm that has spiral grooves cut into the inside of its barrel. These grooves, known as rifling, help to spin the bullet as it travels down the barrel, which stabilizes its flight and improves accuracy. This design allows for greater range and precision compared to smoothbore guns, which lack these grooves. Rifled guns can be found in various forms, including rifles and handguns. They are commonly used in hunting, sport shooting, and military applications. The invention of rifling significantly advanced firearm technology, leading to more effective and reliable weapons in history, such as those used in the American Civil War and by famous figures like Daniel Boone.
