ABSTRACT:
An improved rotating band for a projectile is disclosed. The rotating band omprises a plastic sleeve, two micarta inserts, and a retainer ring. One micarta insert, located in the middle of the plastic sleeve, contains grooves which increase the friction coefficient and elasticity of the rotating band. The second micarta insert, located further forward, provides additional barrel contact area. These improved characteristics enable the projectile to be retained in a hot gun when elevated or rammed at any velocity. A retainer ring is molded onto the aft end of the plastic sleeve to secure the invention to the projectile. The rotating band also acts as a seal and spins the projectile as it moves through the gun barrel. The rotating band disintegrates after the projectile exits the gun barrel.
