Abstract: A method of mass-producing one-way luminescent projectiles includes providing projectiles each including a body having a nose and a trailing end including a perimeter edge and a rear surface, and that is symmetrical about an axis that extends centrally through the body from the nose to the rear surface, securing the projectiles in a nose down, trailing end up orientation leaving the rear surfaces exposed, depositing a quantity of a hardenable photoluminescent material centrally on each rear surface, the quantities being identical and hardening over a period of time, and maintaining the projectiles in the nose down, trailing end up orientation during the period of time such that each quantity of photoluminescent material forms an identical solid photoluminescent body adhered to the respective rear surface, that is concentric with, and extends outwardly no further than, the perimeter edge, and radially symmetrical relative to the axis.

Abstract: A projectile for piercing armor includes an outer jacket built around a penetrator assembly. The penetrator assembly includes an inner jacket, a penetrator, and an incendiary charge. The inner jacket includes a leading part and a trailing part. The incendiary charge is carried by the leading part of the inner jacket. The penetrator is made of an armor-piercing material and includes an armor-piercing leading extremity, a trailing extremity, and an outer surface. The armor-piercing leading extremity extends into the trailing part of the inner jacket, and the inner jacket bears against the outer surface of the penetrator between the armor-piercing leading extremity and the trailing extremity. An empty space within the inner jacket is between the armor-piercing leading extremity of the penetrator and the incendiary charge.
