Abstract: A projectile for use with a firearm having a rifled barrel can include: a substantially cylindrical projectile body having at a front end a 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 pilot band section formed on the projectile body forward of the driving band section. The nose section can be formed having an LD-Haack profile.

Abstract: A projectile for use with a firearm having a rifled barrel can include: 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-off section formed on the projectile body adjacent to the driving band section on a rearward 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-off section on a rearward side thereof. The driving band lead-off section can be formed having an LD-Haack profile.

Abstract: A projectile for use with a firearm having a rifled barrel including helical grooves extending longitudinally along an inner surface thereof can include: 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 pilot band section formed on the projectile body forward of the driving band section.
