Gentlemen,

Johannsen in Germany makes custom rifles in this caliber.
(www.johannsen-jagd.de)

Cases are not listed in the Horneber standard catalogue (http://www.huelsen-horneber.de/frame.html) but he produces also cases for custom orders.
If we find enough people interested in this caliber, we can make a collect order...
I would step in with both feet! :-)

Energy level:
Assumed that the .375 H&H is equal to 9,3x64, then the 9,3x70 should be similar to the .375 Weatherby.

And now with the 320grs bullets in 9,3mm from Degol (or Woodleigh?) available!

best regards
Rolf
