The DWM Modelo Argentino 1909 is the best original mauser action made. They did not rush things in Berlin back then

The .500 Jeffery is a great killer you can use mine all you want.
The .500 Jeffery is 10 mm shorter then the Gibbs but more powerfull 100 fps

Then .500 Jeffery can be made on a DWM Modelo Argentino 1909 action with modifications. Harald Wolf has done it many times. He made on for Tony Sanchez Arino. Now he is sponsered by DUMOULIN-HERSTAL http://www.dumoulin-herstal.com/index_fr.htm

Fine company.

The CZ action is ok but does not feel like the DWM you know what I talk about

Cheers,
