摘要： A projectile (110) is provided with a projectile tip (120) having enhanced aerodynamic properties to improve accuracy of the projectile. The tip has a body having a base or lower end (128), an upper end (133) and a curved, side wall (163) between its upper and lower ends that defines an ogive tip length. The tip is received with a projectile jacket (140) and also can have a series of aerodynamic features (155) formed in its body to modify air flow about the body of the projectile in flight.
