A rotating tubular projectile for increasing the stability of the projectile and the accuracy of the firearm. The rotating tubular projectile includes a cylindrical body having an open first end. The cylindrical body has an axial passageway that extends through the open first end. Additionally, a spiraled airfoil is mounted in the axial passageway of the cylindrical body for impinging a flow of air flowing through the axial passageway. In one embodiment of the present invention the spiraled airfoil rotates the cylindrical body with respect to a longitudinal axis of the cylindrical body as it travels through the barrel and away from the firearm.
