Hollow Tube Projectiles and Launch Systems Thereof

A hollow tube projectile configured with a leading edge to first exit a firearm barrel and a trailing edge to follow there through, the hollow tube projectile comprising:

• an annular airfoil slug, a cross section thereof resembling an airplane wing having a rounded leading edge and a sharp trailing edge and an outer lifting surface there around and an inner pressure surface;
• a plurality of three or more fins distributed equidistantly around the annular airfoil slug, each fin having an inner edge complementary to the outer lifting surface of the annular airfoil slug and an outer edge parallel to a major axis through the annular airfoil slug;
• and
• a launch wafer adapted to contain combustion gases during a launch of the annular airfoil slug, the launch wafer also adapted to concentrically position the annular airfoil slug within a hollow tube cartridge.
