Abstract
A ball or projectile for small caliber ammunition is disclosed. The projele is useful in training ammunition for the training of personnel on firing ranges having a limited area and a maximum range which is below the range of the standard service round for the weapon on which the training is conducted. The projectile has a body including an ogival forward section, a cylindrical center section, and a conical trailing section. A plurality of fins is mounted longitudinally on the conical trailing section for generating spin dampening torque to cause gyroscopic instability and thereby create high aerodynamic drag upon said projectile when fired from a weapon.
