ABSTRACT:
A mold for a grooved hollow point bullet having a pair of separable mold halves which are mounted in a bullet molding apparatus for movement between a closed position and an open position. Each mold half has a flat parting surface which has a bullet shaped groove and an elongated shallow groove which extends from the bullet shaped groove to one end of the mold half. When the mold halves are in the closed position so that the parting surfaces of the mold halves abut, the bullet shaped grooves of the mold halves combine to form a bullet shaped cavity and the elongated shallow grooves combine to form a bore which leads from the bullet shaped cavity to the end of the mold. An elongated pin for forming a hollow point bullet is mounted on one of the mold halves so that it extends through the bore and into the bullet cavity. The pin is mounted on one of the mold halves so that it remains with the mold half throughout the casting process, including the separation of the mold halves and ejection of the cast bullet from the mold.
