Abstract

This is a study of commercially available .22 caliber rimfire ammunition manufactured to explode on bullet impact. Factors considered were bullet velocity, angle of impact, missile deformation, and depth of penetration and cavitation in ordnance gelatin. Microscopic, radiographic, and high speed motion picture photographic techniques were employed. This study found that the angle of impact was critical for detonation of the bullet.
