Armor piercing projectile construction

Abstract

A firearm projectile including a penetrating central body, a tip at the forward end of the body. An outer encasement component around a portion of the central body. A displacement shroud around the outer encasement arranged to provide force specific energy transfer and projectile stabilization during integral flight from a firearm.

1 . An armor penetrating projectile cartridge comprising,
 a cylinder cartridge hull having an open end in an oppositely disposed brass head closure,   a bi-metal projectile within said cartridge hull having a hardened steel central core and a hardened steel jacket thereabout,   said steel jacket having a central cylindrical opening partially within,   said bimetal projectile having a cylindrical body portion engaged within said steel jacket's central cylindrical opening and a fusto conical portion extending from said steel jacket,   a one-piece sabot engaged around and abutting said steel jacket and extending there beyond,   a resilient pad between said steel jacket and sabot,   a cartridge wad in abutment with sabot and a propellant in said cartridge hull,   said central core having a higher density than armor plate for penetration thereof.   
     
     
         2 . The armor piercing projectile cartridge of  claim 1  wherein said steel jacket has an annular sidewall and an integral base of increased dimensional thickness to that of said sidewall. 
     
     
         3 . The armor piercing projectile cartridge of  claim 1  wherein said cartridge wad in abutment with said sabot has an oppositely disposed concave surface. 
     
     
         4 . The armor piercing projectile cartridge of  claim 1  wherein said one-piece sabot comprises, an annular sidewall, annular spaced cuts in said sidewall, an integral solid base of a dimensional thickness equal to that of said know cartridge wad. 
     
     
         5 . The armor piercing projectile cartridge set forth in  claim 2  wherein said steel jacket annular sidewall has a tapered free edge in angular registration with said central core frustro conical portion. 
     
     
         6 . The armor piercing projectile cartridge set forth in  claim 2  wherein said composite bi-metal projectile frustro conical portion end is in planar alignment with said sabot's annular sidewall upper free edge. 
     
     
         7 . The armor piercing projectile set forth in  claim 1  wherein said cylinder cartridge hull has a crimped free annular open end engaging said sabot. 
     
     
         8 . An armor penetrating firearm projectile comprises, in combination, a cylindrical outer hull,
 a bi-metal projectile within said hull comprising a hardened steel center core and a hardened steel jacket partially there about,   a sabot having a face and an integral upstanding sidewall receiving said bi-metal projectile,   a resilient pad between said steel jacket and sabot base,   a cartridge was in abutment with said sabot,   a propellant and primer in said hull in communication with said wad,   said steel center core having a fusto conical target engagement end portion.
