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).

Ammunition

An ignition transfer body for a propellant-charge module is coaxially surrounded by a supporting tube and includes at least one clear ignition channel. The ignition transfer charge is composed of a first propellant-charge powder generating thermal energy in a range of 3 kJ/g to 4.5 kJ/g, and the supporting tube is composed of a second propellant-charge powder. Preferably, the second propellant-charge powder forming the supporting tube is pressed powder which is extruded or pressed in a mold.
