Boat Tailing - Tapering that part of the projectile behind the driving band so as to reduce air resistance (drag), especially at low velocities. This type of design gives a projectile greater range but tends to increase wear on the gun barrel. It was long thought that boat tailing caused greater dispersion in the impact pattern, but a study published in 1978 by the US Army's Ballistic …
