A single fragment cannot be accelerated very well and undisturbed by an unconfined high explosive charge. The converging shock and release waves eject a higher number of very small spall debris of the fragment in the firing and target direction. This means, the fragment is considerably deformed and looses some mass. In addition, the release waves reduce the high pressure zone after the fragment very fast. Therefore, only moderate velocities are achieved.
