Abstract: Non-standard sport projectiles, in accordance with this invention, include at least one linear through hole. As this non-standard sport projectile passes through the air, after being hit by, for example, a golf club, the non-standard sport projectile spins. When the above-mentioned through hole is generally aligned with the projectile's direction of flight, air passes through the through hole, and the aerodynamic characteristics of the non-standard sport projectile are enhanced. When the through hole is not aligned with the projectiles direction of flight the aerodynamic characteristics are reduced. As a result, the non-standard sport projectile experiences rapidly repeating intervals of relatively high aerodynamic flight and relatively low aerodynamic flight as the non-standard sport projectile spins around the center cross section of the through hole.
