Upset jacketed bullets
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.
1. A projectile comprising a jacket including nose, middle, and heel portions, the nose portion including a forward cavity, the heel portion including a rearward cavity having sidewalls, and a dense core within the rearward cavity and bonded to the sidewalls, a tip at least partially positioned within the forward cavity, the projectile configured so that upon upset of the projectile, the portion of the jacket forming the forward cavity peels generally back toward the heel portion thereby forming petals, 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.
2. A projectile comprising a jacket including nose, middle, and heel portions, the nose portion including a forward cavity, the heel portion including a rearward cavity having sidewalls, the jacket is softened adjacent the rearward cavity, and a dense core within the rearward cavity and bonded to the sidewalls, configured so that upon upset of the projectile, the portion of the jacket forming the forward cavity peels generally back toward the heel portion thereby forming petals, 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.
