A boron steel high pressure cartridge case and method of manufacturing the same is provided. The method includes cold forming a cartridge case into a drawn blank or a tubular component; annealing the cartridge case using a belt furnace, flame furnace, induction furnace, or a batch furnace; performing a machine ejector slot and trim on the cartridge case; forming the shoulder and neck of the cartridge case; performing a heat treatment of the cartridge case; tempering the cartridge case; and coating the cartridge case with a zinc nickel plating. The cartridge case is fabricated of boron steel including 1.0% boron.

Ammunition casings are described that include a base, a body coupled to the base, and one or more patterns on the body.

A method of sealing an ammunition cartridge during an ammunition manufacturing process. The method including providing a cartridge case having a projectile receiving mouth with an inner surface and applying a thin circumferential film of a liquid light curable sealant to the inner surface. A cured thin circumferential film is formed by curing the thin circumferential film of liquid light curable sealant using an effective curing light from an optical light spectrum. A projectile is inserted into the mouth of the cartridge case with the cured thin circumferential film forming an air and moisture impermeable seal between the inner surface and the projectile.
