A casing bottom for a propelling charge including a circular ring shaped (annular) base plate (1) which accommodates a centrally arranged primer sleeve (7) in a form-locking manner. In order to be able to unload ammunition, particularly two-part ammunition including sub-caliber projectiles, the rear surface of the primer sleeve is provided with a recess for form-fittingly receiving an extractor. Preferably the recess is of a size which can be accommodated on a sub-caliber projectile.
