A training cartridge projectile for use in either a plastic cartridge case or a conventional metal cartridge case is disclosed that contains no explosive material. The projectile has an insert having a body portion and a front end, a container overmolded onto the body portion of the insert, a frangible ogive fastened to the front end of the tubular insert; and a payload module within the ogive in front of the container carrying a nonexplosive signature material for providing a visual indication of projectile impact to an observer upon projectile impact with an object. The module includes a hollow frangible ampoule containing the signature material, and a generally disc shaped base member engaging the insert and closing the ampoule. The base member preferably has a set of axially extending vanes engaging the signature material during spin-up as the projectile is accelerated through the bore of the weapon firing the projectile.
