A sequence of photos showing a frangible bullet fracturing when subjected to high velocity strain waves
Frangible bullets are intended to disintegrate into tiny particles upon target impact to minimize their penetration of other objects. Small particles are slowed more rapidly by air resistance, and are less likely to cause injury or damage to persons and objects distant from the point of bullet impact.
Most frangible bullets are subject to brittle failure upon striking a hard target. This mechanism has been used to minimize the tendency of malleable lead and copper bullets to ricochet from hard targets as large, cohesive particles. Brittle failure may occur at subsonic velocity. Attempting to crimp a brittle frangible bullet into the cartridge case may break the bullet.[1] Brittle frangible bullets may break during the self-loading cycle of semi-automatic firearms;[2] and those fired from revolvers often break as the bullet encounters the barrel forcing cone after leaving the cylinder.[3]
