Abstract

Improvements in a multi-capability projectile having a heavy primary penetration element surrounded by a splintering and fragmenting secondary penetration element which extends forwardly of the primary penetration element to form a cavity having a bursting charge therein, the projectile having a nose portion forwardly of that cavity with an ignition charge therein. The rear of the secondary penetration element is stepped inwardly to form a smaller recess which receives and holds the rear end of the primary penetration element. A shoulder adjacent this smaller rearward portion can be formed in accordance with an improved method with an annular groove, according to which the portion of that shoulder radially inwardly of the groove is urged against the side of the primary penetration element to form a rimmed part which secures the same. The annular space surrounding the forward end of the primary penetration element can be filled with an incendiary charge, the bursting charge being located forwardly thereof. The forward end of the secondary penetration element can be tapered inwardly to better confine the charge.
