I have been interested in the 9.3X64 for quite some time. It is a cartridge that deserves more credit that it is getting. I have heard that the Russian army are now using it as their answer to our .338 Lapua. I think it is the same cartridge with the same C.I.P. specifications. An interesting point is that from the 1970s on Steyr Mannlicher chambered their rear locking lug rifles in this caliber. That is not the case with their newest rifle, nor is the M12 Mauser chambered for this round. Pity I would have liked to have purchased one. It is really great cartridge. I guess I will have to stay with my .375 H&H
