Abstract
A projectile particularly for use in rapid fire weapons and high performance guns comprises a hollow projectile body having an exterior surface with an annular groove therearound and with a plurality of openings formed in the groove at spaced circumferential locations. A rotating band is positioned in the groove and secured against displacement caused by centrifugal and accelerating forces, portions of the band which extend through the openings. The band is advantageously injection molded directly in the groove so that portions thereof form into the openings and extend through the openings and form a closed ring on the interior of the shell of the projectile body.
