System for Inspecting the Mass Center of a Fire Arm Bullet

摘要

Appraise the properties of bullets synthetically, a fine instrument for inspecting the mass-center of a small bullet precisely is developed. The instrument is used to inspect the place of axial center of gravity and the radial eccentricity of small bullet. The composition and working principle of the system are expounded, the measuring precision of the system has been analyzed theoretically, the results measured have been given.
