Have you any links or further info about that? I am familiar with the S-Ball Plastik, but as a shotgun slug made by Sellier and Bellot some years back. A good one too, it was made of plastic with a solid iron core, but of course it was nothing like the one pictured n the OP, which looks exactly like Norma PPDC I've used, even down to the yellow colour on the plastic point.
