Abstract
Anchoring of a spin-stabilized projectile with a sabot body is provided by grooves arranged on the fin-stabilized projectile, which are engaged by ring-shaped protrusions provided in an axial bore of the sabot body. The distance of the first protrusion from the predetermined breaking points of the sabot body and the height of the protrusions are selected in such a way that the deformation at the predetermined breaking points in case of assembly-related spreading of the segment lies in the resilient range.
