bullet, an elongated metal projectile that is fired by a pistol, rifle, or machine gun. Bullets are measured by their caliber, which indicates the interior diameter or bore, of a gun barrel.

Early bullets were round lead balls that were loaded down the muzzle of smoothbore weapons and propelled by the ignition of a physically separate charge of black powder. Modern bullets were developed in the 19th century for use in small arms that had rifled barrels. In these rifles, a system of helical grooves cut into the interior surface of the gun’s bore imparts spin to the bullet during its passage. The spin enables a bullet to maintain a point-forward attitude in flight, and under these conditions, an elongated bullet with a pointed tip is aerodynamically much superior to a round ball; it sustains its velocity much better in flight, thereby gaining in both accuracy and range.

Experiments with these “cylindroconoidal” bullets began about 1825, but a difficulty soon arose. The bullets had to fit tightly in the barrel, and it proved difficult to load a tight-fitting bullet in a muzzle-loading gun. The solution was found by Claude-Étienne Minié of France, who in 1849 developed a soft lead bullet with a cavity in its base into which a conical plug was fitted. The bullet’s diameter was small enough that it slid freely down the gun bore, and the sudden inflammation of the propellant charge upon firing drove the conical plug forward to expand the lead bullet tightly into the grooves of the rifled bore.

By the 1860s, percussion caps, which detonate upon being struck a sharp blow by the firing pin of a gun, had been incorporated into a metal cartridge case containing all the components for a complete round that could be used in breech-loading rifles. In the 1880s, the introduction of nitrocellulose, or guncotton, in place of black powder as the propellant charge provided the final element for the modern bullet.
