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.

Claims

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.
