Modern Marvels - Season 10 Episode 47 Bullets

From "safe" bullets that stop hijackers but leave aircraft unscathed to bullets that chain-saw through steel and "smart" bullets computer-programmed to hit a target, this explosive hour examines the evolution of bullets from origin in the 1300s–stones and round lead balls shot from iron and bamboo tubes. Lead balls ruled until 1841 when a conical-shaped bullet changed ammo forever. We learn how to construct a modern cartridge, and at pistol and rifle ranges view demonstrations of modern firepower.
