Countless pieces of roe deer have already been shot with the legendary GECO partial jacket. The bullet can be used universally and can cope with almost all hunting situations. It responds reliably in the game's body and has a good target ballistic effect. The thin-walled bullet jacket is the secret of this successful design. The deformation is initiated by the pronounced lead tip and the sheath adapts to the target resistance. The deformation process can only be controlled to a limited extent on strong game, so that a reject cannot always be expected.
