Abstract: A projectile for a large caliber gun including a fall-back preventer ring disposed within a fall-back preventer recess defined by the projectile. The fall-back preventer ring engaging the barrel of the large caliber gun during a loading cycle and releasing from the barrel when the projectile is fired. The fall-back preventer ring is a multifaceted split ring device sized for both axial and radial movement within the fall back preventer recess. The present invention thus maintains the projectile safely within the barrel during loading and in the presence of other external forces.
