Abstract

A full-caliber projectile having a cylindrical guide region (5) and an ogival projectile tip (7). To improve the stabilization of the projectile (1) inside a gun barrel (2) in a simple manner, and therefore improve the intermediate ballistics and hit accuracy over those of comparable projectiles, a guide ring (8), which is segmented in the circumferential direction, and whose outer diameter is smaller than the inner diameter of a gun barrel (2) of the same caliber, is secured to the projectile tip (7) such that the radially spaced guide-ring segments (9) detach from the projectile (1) in the gun barrel (2) when a predetermined firing acceleration occurs in the gun barrel, and the segments (9) are pushed toward the projectile (1), axially relative to the cylindrical guide region (5), by dynamic pressure until they rest against the inside wall (18) of the gun barrel (2) and against the projectile (1).
