Projectile with enhanced ballistic efficiency

A projectile for use with a firearm having a rifled barrel including helical grooves extending longitudinally along an inner surface thereof, the projectile comprising:

• a substantially cylindrical projectile body having at a front end an ogival nose section and at a rear end a tail section;
• a driving band section formed on the projectile body between the nose section and the tail section;
• a bore rider section formed on the projectile body between the nose section and the tail section;
• and
• a driving band lead-on section formed on the projectile body adjacent to the driving band section on a forward side thereof and having an angled surface, with respect to a horizontal axis of the projectile body, that forms a transition from the driving band section to a portion of the projectile body adjacent to the driving band lead-on section on a forward side thereof,
• wherein the driving band lead-on section is formed having an LD-Haack profile.
