That Hallowell 9.3x64 is quite sweet, and appears to be well made.

All these large metrics are great calibers, but have little or nothing to offer over the .338, 375. Mostly they are another caliber to play with, and they are good ones..Comparison is a waste of time, the buffalo will never know it.

I love my 9.3x62s that come and go around here, but the 338-06, 35 Whelen, 338 Win, 375 H&H or Ruger are all about the same when the bullet hits big boys, its always gotta be in the right spot in which case the end result never changes.
