Abstract
A multi-stage fragmenting projectile has a number of grooves and slots that are strategically placed on and around the periphery of the projectile. After the projectile engages an object, a first set of fragments separates from a main body of the projectile. A second set of fragments separate a short time later after the projectile has traveled farther in the object.
