I own a M70 in .375 H&H and I like it.
The reasons I like the 9.3x62 over the .375 H&H are real simple:
(I'm speaking of the CZ in this regard, which I also like)
1.) Proven medium bore power in a lighter, -'06 sized action.
2.) Six available shots without reloading (5 in mag, one in chamber).
The rest is fodder for reloading bench banter.
