Special purpose firearms projectile
摘要:
A small arms bullet with controlled flight characteristics fireable at high velocities from conventional small arms. The bullet has a projecting spike tip forming a supersonic shock wave cone. The bullet travels inside this shock wave cone and has low aerodynamic drag at supersonic velocities. The bullet is light weight and has a blunt drag face providing a high aerodynamic drag configuration for the bullet at subsonic flight velocities to rapidly decelerate the bullet after a preselected initial combat range, thereby reducing its long range danger to bystanders and property. Within the preselected combat range the shape and velocity characteristics of the bullet provide high ''''stopping power'''' yet a reduced lethality.
