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 bullets had to fit tightly in the barrel, and it proved difficult to load a tight-fitting bullet in a muzzle-loading gun. 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.Įxperiments with these “cylindroconoidal” bullets began about 1825, but a difficulty soon arose. 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. Modern bullets developed in the 19th century for use in small arms that had rifled barrels. ( See bore.)Įarly 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. Bullets are measured by their calibre, which indicates the interior diameter, or bore, of a gun barrel. The 155 mm howitzer round is one of the most requested artillery rounds of the Ukraine warīullet, an elongated metal projectile that is fired by a pistol, rifle, or machine gun.
