Hollow bullet with internal structure

摘要

A bullet has a cylindrical body portion and a conical tip monolithically formed with the body portion. The bullet is hollowed out to form an internal cavity. A sidewall defines the structure of the body portion and the conical tip. Bullet structure provides for a bore size, low weight, high velocity, and low recoil projectile having a full-bore size that does not have to expand to a larger diameter during firing in order to transfer its energy to a larger wound channel. In one embodiment, a plurality of recesses is provided on the body portion and extends through the sidewall. The recesses are disposed circumferentially in the radial direction and are offset longitudinally along a longitudinal axis of the bullet. The internal cavity includes a plurality of trusses extending in a radial direction. Instead of or in addition to, the trusses, the wall of the internal cavity may include one or more ridges.

主权项

1. A bullet for use with a weapon having a barrel, the bullet comprising:
a hollow, cylindrical body portion; a conical tip monolithically formed with the body portion, the body portion and the conical tip defining an internal cavity; a plurality of recesses provided on at least one of the body portion and the conical tip, the plurality of recesses extending at least partially through a sidewall of the bullet; and at least one truss extending radially across a portion of the internal cavity from an interior portion of the sidewall, wherein the at least one truss includes a plurality of spokes extending radially outward from a central longitudinal axis of the internal cavity to an interior portion of the sidewall, the plurality of spokes separated by empty hollow spaces extending through a full thickness of the at least one truss, wherein the recesses are disposed circumferentially in the radial direction of the bullet and are offset longitudinally along a longitudinal axis of the bullet, wherein the at least one truss has an upper surface facing the conical tip and a lower surface opposite the upper surface, and wherein the sidewall of the bullet is thickened in a location of the at least one truss.
