Abstract
A projectile having improved accuracy when fired over long ranges is formed from a monolithic block of a copper alloy. Proceeding from a nose to a heel of the projectile, is a fore portion with arcuate side walls, a body portion of substantially constant cross-sectional area that minimally contacts a rifled gun barrel, a drive band having a diameter effective to seal propellant gases and an aft portion that continuously decreases in diameter terminating at the heel. A cylindrical bore extends from an opened end at the nose to a closed end proximate to a transition plane between the fore portion and the body portion.
