I see a lot of postings regarding the 9.3x62, but I rarely see anyone posting anything about the 9.3x64. Is the bigger 9.3x64 cartridge really popular in comparison to the 9.3x62? Looking at the velocities, the 64 really is the 375 while the 62 only comes close. The 64 fits into a 30/06 action length, so I would expect it to be pretty popular.

Odd case head size and hard-to-find brass and ammo are it's limitations. The x64 is certainly the equivalent of the 375; not too sure if the power advantage over the x62 is all that meaningful.
