An impact part on a projectile permits the activation of detonation systems within a large angular range of contact with a target. The impact part is provided with annular recesses with embedded circular rings that engage with the target and prevent the projectile from rebounding. A thin-walled, dome-shaped tip prevents relatively large disruptive effects upon the projectile's hollow charge. As a result of dimensioning the impact part in accordance with the rules of fracture mechanics, it is possible to achieve a desired fragmentation on the target.

An impact part according to claim 1, characterized in that the embedded elastomers are in the form of annular seals. 3. An impact part according to claim 2, characterized in that the annular seals are O-rings of silicone rubber. 4. An impact part according to claim 1, characterized in that the internal shape of the impact part has in internal shape with a profile which displays discontinuities. 5. An impact part according to claim 1, 2 or 3, characterized in that the impact part has an external thread, the thread and an external shape of the impact part being adapted to a contour of a head of the projectile. 6. An impact part according to claim 1, characterized in that an external shape of the impact part and the grooves are selected to be such that a line of contact with a target forms an angle a of from 15째 to 90째 to the flight direction F. 7. An impact part according to claim 1, characterized in that the tip is dome-shaped and has a wall thickness and material selected such that the tip shatters at least in part upon impact with a hard target at an angle of from 80째 to 90째. 8. An impact part according to claim 1, characterized in that it comprises an untempered heat-treatable steel.
