Abstract
A small arms projectile containing a series of vents or apertures in a geometric arrangement such that the projectile's leading edge is capable of penetrating the target without structural failure and depositing the majority of its residual energy in the target. In addition, the design of the body allows the projectile to be spin stabilized when fired from any suitable weapon.
Claims1
A projectile for small arms ammunition to be fired from a small caliber gun at a lightly protected target consisting of:
- an elongated tubular body provided with a forward end and a rear end all of which is symmetrical about a center axis,
- a center axial hole passing through the entire length of said body and symmetrical about said center axis,
- a plurality of hollow venting straight passages in spaced radial relationship around said body, and
- each of said passages in said forward end having an entrance in an outer surface of said body, and an exit communicating with said center hole, and
- each of said passages longitudinally directed inwardly towards the rear end and oriented on an axis angularly displaced at least 45.degree. from said longitudinal center axis, whereby a rapid energy deposition occurs upon entering said target without over-extending the same.
