Abstract
A part of a cover is pressed radially into a circumferential groove contour in a projectile body by a preferably rigid die, which need only be moved axially and which is provided with a special outer contour. An outer contour should be matched to the groove contour or vice versa, so that the material of the cover that is formed radially by the forward-moving die can be pressed into the groove contour of the projectile body, and the cover no longer has any degrees of freedom after the forming, so that it is secured with respect to the tracer or the like. The cover is preferably a cover ring.
