Abstract

A jacketed hollow point bullet having a lead core and the method of making same with the core having a downwardly extending cavity having side portions terminating adjacent the peripheral edge of the jacket, with slits being formed in the peripheral edge of the jacket and down through the adjacent side portions of the core.

Claims

1. A mushrooming hollow point bullet having a base and a lead core having a central recess in a front open end of the core, the core being surrounded by a jacket which has a front open end terminating at the front open end of the core, the improvement comprising a plurality of downwardly projecting spaced slits extending through the front open end of the jacket to form spaced petals having side edges extending through the front open end of the lead core into the central recess to form petals of core material and jacket material between the spaced slits and wherein the jacket material extends into the slits to said central recess which permits the petals of core and jacket material to separate and form outwardly projecting petals.

2. The bullet of claim 1 wherein the front open end of the core extends downwardly toward the bullet base and terminates in an inverted ogive configuration.

3. The bullet of claim 1 wherein the bullet has a base portion and a driving band near the base portion.

4. The bullet of claim 1 wherein said slits are at an angle to a longitudinal axis of the bullet to form angularly disposed petals that are overlapped.
