40x46 SHOCK PDB

Does anyone have information on a 40x46 SHOCK less lethal baton round?
Who is PDB?

Any chance to see the complete round and possible other markings including the headstamp?

This cartridge was made by Nobel Sport France. I don’t have documentation explaining its meaning, but I think it stand for “Point-de-Buis”, that is the location of one of their factories.

Fede

I only had the one photo prepared. The round is not mine, it is in an ongoing auction.

Thank you Fede.
