US12422231 - Spinning projectile

A projectile, includes a head having a forward tip and a rear end, a stem extending from the rear end of the head and formed integrally with the head, and a sleeve positioned adjacent to the head and being collinear with the head and coaxial with the stem. The sleeve is hollow and substantially cylindrical and has an inner diameter and an outer diameter. A base is formed integrally with the stem by pressing a rearward end of the stem and expanding a rear dimension of the stem to capture the sleeve between the base and the head. The head and the base are rotatably dependent upon each other by connection with the stem, and the head, stem, and base are rotationally independent of the sleeve.
