Abstract
A method for casting a rotating band onto a projectile having a metallic ll, with a nose at one end, a closed base at the other end, and a hollow core axially formed within said shell. The method comprises the steps of (a) forming a projectile mold having three sections, a first section for the nose, a second section for the closed base, and a third section for the rotating band seat; (b) casting hot metal into the mold; (c) removing the mold from the third section so as to expose the rotating band seat therein; (d) clamping a ring mold about the rotating band seat; (e) casting hot metal into the ring mold to form a rotating band within and above the rotating band seat; and (f) cooling the projectile.
