Plastic bullet
First Claim
1. A bullet projectile comprising:
- a body portion having a blunt forward end and a rearward end, said body portion being frustoconically shaped and including a larger base comprising said forward end and a smaller base comprising said rearward end, whereby, during travel in a firearm barrel, said frustoconically shaped body creates air turbulence along the side of said body portion to coact with any rifling in the barrel, said body portion defining a plurality of pockets about the body circumference, said pockets being separated by ribs longitudinal to said body, each of said pockets terminating short of said forward end of said body, each of said ribs tapering from said forward end to said rearward end, each of said pockets including a floor comprising a segment of a right circular cylinder; and
means for securing said rearward end of said body portion to a bullet casing, said securing means being concentric with and diametrically smaller than said rearward end of said body portion.

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.

6. An improved bullet including a projectile, having a stud, and a casing having a chamber wall defining a chamber for closely receiving said projectile stud to retain said projectile in said casing, the improvement comprising:
-
a plurality of annular, uniformly axially spaced ridges extending from said stud; and said chamber wall having a plurality of annular, uniformly axially spaced serrations, the spacing of said serrations being different from the spacing of said ridges, whereby not all of said ridges and said serrations will matingly engage at one time regardless of the axial orientation of said stud within said chamber, whereby said projectile releases from said casing relatively smoothly. - View Dependent Claims (7)
