Abstract
An elongated tubular projectile is provided comprising a tubular side wall structure having inner and outer surfaces and an annular chamber formed between the inner and outer surfaces for receiving explosive material. The annular chamber can be provided with an internal peripheral surface adjacent to the outer surface of the tubular side wall and a grid of intersecting grooves formed in the internal peripheral surface to facilitate the production of a uniform distribution of fragments. Additionally, the projectile can be provided with a central portion and a nose portion having inner and outer walls adjoining the central portion. The inner wall of the nose portion can comprise a liner which, upon ignition of the explosive material, collapses upon itself and is propelled forward to define a self-forging armor piercing fragment.
