A muzzleloader is a type of firearm that is loaded from the front, or muzzle, of the barrel. This loading method typically involves placing a projectile, such as a bullet or ball, along with gunpowder into the barrel before firing. Muzzleloaders can be powered by either black powder or modern substitutes and are often used for hunting and sport shooting. Muzzleloaders come in various styles, including rifles and shotguns, and can be single-shot or multi-barrel. They have historical significance, as they were commonly used from the 16th century until the mid-19th century, before the advent of breech-loading firearms. Today, they are popular among enthusiasts and are often featured in events like the National Muzzle Loading Rifle Association competitions.
