ABSTRACT:
A projectile for an air arm is integrally formed from a single piece of dense malleable material formed as a body of revolution about a longitudinal axis having a head portion dimensioned for free sliding in the bore of an air arm and a skirt-like portion of frusto-conical form. The rearward end of the skirt portion is dimensioned to be in slight interference fit with the bore and the forward end is joined with the head portion to define a reduced diameter waist. The frustum is shell-walled, having a central recess opening to the rear and extending forwardly into the head portion. The head portion has a parabolically shaped outer surface which transitions smoothly into a hyperbolically shaped outer skirt surface for aerodynamic efficiency. Vanes are formed on the head portion to enhance in-flight spiraling rotation.
