Abstract

A practice projectile without an explosive for firing against a practice target with large-calibered weapons, wherein the projectile incorporates a projectile body which is in the configuration of a cylinder and which possesses a conical nose cone. The projectile includes a nose cone which is constructed in the shape of a truncated cone having a flat leading end surface with a diameter of about 0.08 to 0.1 that of the projectile caliber, wherein the nose cone forms a sharp contact edge with the cylinder of the projectile; a ratio in the length of the nose cone to that of the cylinder of approximately 1:1.+-.5%; a location of the center of gravity of 3 to 3.5 times the projectile caliber, measured commencing from the leading end surface; and a ratio of 4.0 to 7.0 for the moments of inertia between the transverse and longitudinal moments.
