Abstract
A projectile rotating band (7) is firmly connected, through openings (9) in the projectile casing (2), to a sealing section (10) at the rear of the projectile inside the projectile casing (2). The rotating band (7) is formed together with the sealing section (10) in the course of a single step of the manufacturing process by injecting a synthetic material into the projectile casing (2) through its open back. The band (7) is prevented from twisting off during firing by the unitary construction, and will not abrade the barrel since it is non-metallic.
