Paati,

I'm wondering if the reason for your question is that you have such a Sauer drilling with a rifle barrel in a caliber you have been unable to identify. If that is the case, I would recommend having a chamber cast made and comparing the dimensions of the chamber cast with the known dimensions of the various 11mm cartridges you have listed. Since there can be a great deal of difference in the pressures generated by the various 11mm loadings, it is certainly important to have exact information concerning the cartridge you are dealing with.

Don't forget to have an accurate cast of the rifle bore made, as well. Exact bullet size is another important factor.
