<p>An ammunition projectile (10) of enhanced flight characteristics, having a boattail portion (16) and including a circular land (18) provided on the rear surface (17) of the boattail portion and concentric with the longitudinal centerline (23) of the projectile, the land having a circular concave wall (22) extending from the flat rear face (17) of the boattail portion to a circular flat surface (22) of the land. Among other things, the projectile exhibits a lesser rate of velocity deceleration along its flight path to a target than like projectiles that do not include the land.</p> |
