Abstract
The specification discloses a plastic bullet having improved accuracy and reusability. The bullet comprises a projectile, including a body and a stud, and a casing, defining a chamber for closely receiving the projectile stud. The projectile body has a reverse frustoconical shape and a blunt forward end defining a spherical segment depression. A plurality of pockets are defined by the body about its circumference. Both the case chamber wall and the projectile stud include interfitting serrations having different axial spacings to improve compression and releasability during firing. The projectile is hollow having a wall-mass-to-diameter ratio providing an improved gyroscopic effect. The casing includes a thick-wall blast chamber providing improved strength and reusability and enabling the use of high force primers.
