Abstract: The present invention relates to a deformation and/or partial fragmentation projectile comprising a jacket and a two-part core arranged within the jacket and having a projectile front-sided core part and a projectile rear-sided core part, the core being attached to the jacket such that the projectile rear-sided core part is more strongly attached to the jacket than the projectile front-sided core part.

Abstract: The present invention relates to a projectile for ammunition, in particular rimfire ammunition, comprising a preferably ogive-shaped nose section and a projectile tail which has an annular recess at an end face, an annular edge circumferentially surrounding the annular recess and radially outwardly delimiting the recess in the circumferential direction, and a projection arranged in the annular recess and extending in the longitudinal direction of the projectile, wherein the annular edge, the projection and optionally the nose section are manufactured in one piece.

Abstract: A magnet holder for attaching a sensor magnet to a motor shaft of an electric motor, including a receiving recess for the sensor magnet and an attachment region for attachment to the motor shaft, wherein the receiving recess is radially delimited by a wall that, over the circumference thereof, includes a plurality of weak spots which have a reduced wall thickness and are designed so that free spaces remain between the weak spots and the sensor magnet arranged in the receiving recess. The invention further relates to a sensor magnet assembly, to an electric motor comprising a sensor magnet assembly, and to a method for producing a sensor magnet assembly. It is the object of the present invention to very reliably and durably attach a sensor magnet to the end of a motor shaft in a very economical and simple manner, wherein adhesive methods are to be dispensed with.
