Chemical analysis of the lead cores and hardness and thickness measurements of the jacket components and lead cores of five caliber .45 M1911 pistol ball projectiles indicate that four of the projectiles are similar. The lead core of one projectile is more highly alloyed and consequently hardner than the others. Slightly lower ballistic limits against helmet and body armor steel are expected from bullets similar to the harder one.
