Abstract

An anti-personnel projectile launched from a weapon shell required at impact to have a low lethality consequence, in which the projectile is fitted in the shell in a shape characterized by a blunt end in the direction of flight and maintained in this shape by oppositely directed air resistance and propelling forces to obviate a change of shape during flight that might cause a serious injury.

Independent Claims | See all claims (10)

  1. 1. A method of shaping a projectile so as to have a specified low lethality consequence upon impact against an individual, said shaping method comprising the steps of using an empty 12 gauge shotgun shell having a cylindrical wall bounding a projectile compartment and a front edge and a rear edge at opposite ends of said cylindrical wall respectively bounding a front and a rear opening into said projectile compartment, closing said rear opening of said 12 gauge cartridge shell with projectile-propelling explosive means, using preliminarily an unfilled tubular projectile body of fabric construction material having a closed front end and a rear edge bounding a rear opening thereinto, filling through said rear opening of said tubular projectile body a selected amount of lead shot, constricting said tubular sock-like projectile body forward of said rear opening to close said rear opening thereby forming a tail, inserting said tail of said tubular sock-like projectile body into said projectile compartment front opening, urging in movement said lead shot-filled closed front end of said tubular projectile body fully into said projectile compartment to an extent causing said tail thereof to contact against said closed 12 gauge shotgun shell end and said lead shot-filled closed front end to expand radially into contact with said 12 gauge shotgun shell cylindrical wall so as to assume said cylindrical shape thereof characterized by a blunt front end, whereby upon igniting said projectile-propelling means said tubular projectile body exits from said 12 gauge shotgun shell projectile compartment in said blunt-ended cylindrical shape against a force of air resistance to flight exerted against a front thereof and pushed by a force urging said shape in flight exerted against a rear thereof such that said blunt-ended cylindrical shape is maintained during flight and prior to impact to thereby contribute to a low lethality consequence.
  2. 9. A method of shaping a projectile so as to have a specified low lethality consequence upon impact against an individual, said shaping method comprising the steps of using an empty 12 gauge shotgun shell having a cylindrical wall bounding a projectile compartment and a front edge and a rear edge at opposite ends of said cylindrical wall respectively bounding a front and a rear opening into said projectile compartment, closing said rear opening of said 12 gauge cartridge shell with projectile-propelling explosive means, using preliminarily an unfilled tubular projectile body of fabric construction material having a closed front end and a rear edge bounding a rear opening thereinto, filling through said rear opening of said tubular projectile body a selected amount of lead shot, delineating said tubular sock-like projectile body forward of said rear opening to close said rear opening thereby forming a tail, inserting said tail of said tubular sock-like projectile body into said projectile compartment front opening, urging in movement said lead shot-filled closed front end of said tubular projectile body fully into said projectile compartment to an extent causing said tail thereof to contact against said closed 12 gauge shotgun shell end and said lead shot-filled closed front end to expand radially into contact with said 12 gauge shotgun shell cylindrical wall so as to assume said cylindrical shape thereof characterized by a blunt front end, whereby upon igniting said projectile-propelling means said tubular projectile body exits from said 12 gauge shotgun shell projectile compartment in said blunt-ended cylindrical shape against a force of air resistance to flight exerted against a front thereof and pushed by a force urging said shape in flight exerted against a rear thereof such that said blunt-ended cylindrical shape is maintained during flight and prior to impact to thereby contribute to a low lethality consequence.
