Briefing: Two kinds of musket

A musket is a firearm loaded from the muzzle. In a smoothbore musket, the inside of the barrel is smooth. In a rifled musket, spiral grooves inside the barrel make the bullet spin as it travels. That spin generally improved accuracy, especially at longer distances. In the early 1800s, many armies relied on smoothbore flintlock muskets. They were comparatively quick to load, and soldiers often used them in close formations. By the Civil War (1861–1865), many soldiers carried rifled muskets, including percussion-cap models. The commonly issued .58-calibre Springfield rifle-musket could be accurate at several hundred yards under suitable conditions, but battlefield accuracy depended on training, visibility, ammunition, and other factors. A smoothbore’s useful range was much shorter, often described as roughly 50–100 yards for aimed fire. These figures are estimates, not guarantees. Rifling did not make every shot hit its target. Loading a muzzle-loading rifled musket could be slower, and soldiers still faced smoke, noise, difficult terrain, and limited visibility. Even as weapon accuracy improved, armies sometimes used close formations and frontal attacks. Historians study this mismatch between new technology and old tactics when examining Civil War battles.
