  • Patent number: 9562753
    Abstract: A projectile according to exemplary embodiments generally includes a jacket with nose, middle, and heel portions. The nose portion includes a forward cavity. The heel portion includes a rearward cavity having sidewalls. A dense core is within the rearward cavity and bonded to the sidewalls. Upon upset of the projectile, the portion of the jacket forming the forward cavity peels generally back toward the heel portion thereby forming petals, and the sidewalls and the dense core axially compress and radially expand to define a bulge portion, with the jacket material substantially covering the dense core material thereby inhibiting exposure of the dense core material to the upset media.

  • Publication number: 20110088537
    Abstract: A bullet includes at least a mid core and a rear core in tandem alignment. The hardness of the mid core is greater than the hardness of the rear core. A jacket envelops both the mid core and the rear core. The jacket has a generally cylindrical sidewall, which is in contact with the mid core, and a boat-tail, which is in contact with the rear core. The rear core is substantially contained within the boat-tail. The mid core and the rear core may be substantially lead-free. In one embodiment, the bullet includes a front core in tandem alignment with the rear core and in contact with a nose portion of the jacket. In another embodiment, the mid core extends from the nose portion of the bullet to the boat-tail.
