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.

1. A rotating tubular projectile for being discharged from a firearm, the firearm including a barrel having an open end extending into a bore of the barrel, said tubular projectile comprising:a cylindrical body having an open first end, said cylindrical body having an axial passageway extending therein through said open first end, said cylindrical body having a plurality of elongated slots circumferentially spaced about and extending through a peripheral wall thereof, each of said slots being generally angled with respect to a longitudinal axis of said cylindrical body; and a spiraled airfoil being mounted in said axial passageway of said cylindrical body for impinging a flow of air flowing through said axial passageway, thus causing said cylindrical body to rotate about its longitudinal axis while exiting through the barrel and away from the firearm, said spiraled airfoil having a plurality of vanes coupled to and radially-extending from a central axis portion of said spiraled airfoil, wherein each of said vanes is positioned in each of said elongated slots extending through said peripheral wall.
