ABSTRACT:
To improve the combustion behavior of a two-part large-caliber ammunition round (10) composed of a primary charge (20) and a projectile charge (30), an annular transfer charge (29) is provided in the primary charge (20) underneath a charge casing cover (28) which terminated the primary charge toward the top. The projectile charge (30) is also provided with an annular transfer charge (39) above its propelling charge casing bottom (38). The transfer charge (29) disposed in the primary charge (20) results in rapid destruction of the charge casing cover (28) and of the casing bottom (38). The annular transfer charge (39) disposed in the projectile charge (30) improves the ignition of the tubular propellant (32) disposed in the projectile charge (30) and of the loose powder charge (36) without noticeable time delays relative to the primary charge (20).
