ABSTRACT:
A shotgun slug having a frusto-conical body that increases a diameter from front to rear and which further includes a plurality of vanes projecting radially from the body which extend obliquely along the length thereof. The top lands of the vanes describe a truncated cone that is axially aligned with the body and which provide an interference fit with the bore of the gun barrel. The pitch of the cone described by the vanes is steeper than that of the supporting body so that the height of the vanes decrease from front to rear. Sufficient radial depth is given to the vanes so that the vanes retain their shape after the slug has been swagged in the barrel during firing. Accordingly, a stabilizing spin is imparted to the slug as it moves through the air towards the target. The slug is further provided with a nose heavy geometry which further enhances its flight characteristics thereby improving both range and accuracy.
