Materials for Bullet Cores

The properties of the materials used for the most common types of small arms bullet cores are discussed. For mass-produced high-penetration, it is most rational to use high-carbon low-alloy steels with the structure of a natural composite and a hardness of about 70 HRC. The best alternative to tungsten alloys, as the materials of the cores of special-purpose armor-piercing bullets, are sparingly alloyed high-speed steels with a high bending...
