Abstract: A spinning, rolling, or roll-stabilized vehicle, such as a projectile, includes a fuselage that rotates about its longitudinal axis (spins) during flight. A collar is positionable relative to the fuselage to steer the projectile, with the collar having ailerons to provide a roll force to position the collar.

The ailerons passively change angle of attack with changes in the dynamic pressure of the projectile. At low speeds the ailerons have a relatively large angle of attack, and at high speeds, the ailerons resiliently reduce their angles of attack, avoiding large rolling forces on the collar.

Abstract: The current invention is directed to a cost effective method of manufacturing bullets or projectiles for firearms which are identifiable after firing and undergoing damage. The mass production of low cost ammunition makes adoption of a requirement that projectiles be so identifiable unlikely unless manufacturing methods and costs are not substantially disrupted.

The tags may have repeated indicia in each projectile and some indicia may be accessible from the outside of a completed round of ammunition. The swaging process retains the identification tags which are protected by the body of the projectile for recovery after the projectile is used.
