1. A method of sealing an ammunition cartridge during an ammunition manufacturing process, the method comprising the steps of:
providing a cartridge case having a projectile receiving mouth with an inner surface;
applying a thin circumferential film of a liquid light curable sealant to the inner surface;
forming a cured thin circumferential film by curing the thin circumferential film of liquid light curable sealant using an effective curing light from an optical light spectrum; and
assembling the ammunition cartridge including inserting a projectile 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.
