A Rifled Muzzle Loader is a type of firearm that has a rifled barrel, meaning it has grooves cut into the inside of the barrel. These grooves help to spin the projectile as it is fired, improving accuracy and range. Muzzle loaders are loaded from the front, or muzzle, of the barrel, which is where the name comes from. This type of firearm was commonly used in the 19th century, especially during the American Civil War. The design allowed for greater precision compared to smoothbore guns, making it a significant advancement in firearm technology. Examples of rifled muzzle loaders include the Springfield Model 1861 and the Enfield Pattern 1853.
