From RWS:

For more than a century now, ammunition products have been manufactured at the RUAG Ammotec GmbH Stadeln factory. The company has had a lively history. In 1855, Heinrich Utendoerffer received permission to set up a laboratory for the production of ignition charges. Utendoerffer then sold his company, which was then still located in Nürnberg, in 1877 to the "Rheinisch Westfälische Sprengstoff-Actien-Gesellschaft" (RWS) founded in 1886 in Troisdorf.

After there were repeated problems in Nürnberg with regards to concession allocations, the factory was moved in 1894 to today's Fürth district of Stadeln. A wide range of products with an "explosive character" are still being produced here today under the control of RUAG Ammotec GmbH. All RWS rifle cartridges are exclusively produced in Germany at the Stadeln location. Production is carefully monitored so that you can hunt successfully and safely.

There is a problem with the double shoulder on your case. I doubt very much that it is an untouched factory round. Looks like some one was playing around with that case. The angles are all wrong and there is some bulging.
