The expanding bullet assembly incorporates a bullet head which incorporates an axial borehole extending from the rear of the bullet head towards the tip but not reaching the tip. The bullet head can incorporate longitudinal serrations or grooves and/or circumferential grooves which aid in separation upon impact. The borehole receives a shaft made of brass, copper or other metal harder than the leaden bullet. The shaft (or pin) extends from the back of the bullet and is connected to an inertial fragmenter, which is separated somewhat from the bullet head. The fragmenter can have tapered or sloped sides adjacent the back of the bullet for wedging into and forcing apart the fragments of the bullet. The bullet head can be round, pointed or hollow pointed. The shaft end near the bullet tip can alternatively be an integral expanded shaft tip having the shape of a sphere. Upon impact of the bullet head, the fragmenter slams into the back of the bullet causing the shaft portion to be forced towards the tip and forcing the bullet apart into fragments.
