A target practice ammunition round includes a missile consisting of a projectile component and a stabilizer component which is equipped with fins and is connected to the projectile component by at least one heat-destructible or combustible connecting element. A delay train commences its operation at the time of the missile launch in that the delay train is ignited by the hot propellant gases which propel the missile during its launch. The delay train ignites a combustible composition the combustion gases of which destroy or ignite the connecting element, so that the latter immediately or eventually releases the two components of the missile for travel in separate trajectories and at speeds which are highly retarded with respect to the speed of the missile due to the increased air resistance following separation. The time delay is so selected that the missile, which would otherwise travel beyond the boundaries of the practice range, disintegrates well within this range and the components thereof fall to the ground still within the range. The missile is a sub-caliber missile which is assembled for the launching operation with a segmented sabot which dissociates itself from the missile immediately after leaving the bore of the launcher.
