Hello,
I have this Ammunition here with the following information:
WR .500 SCHÜLER stamped on it. I have been looking for some
information on this Ammo but couldnt find anything.

On the packaging it says: NITRO EXPRESS CARTRIDGES .500 Schüler 12,7x70
535 GRAIN BULLET SOLID. by WR Ammunition (GERMANY)

Has anyone got pressure information on this Ammo? or any papers
that can help me?
