It may not be in the league of the 375 H&H ..but it surely is neck n neck with the 338 wm loaded with 250 grain bullets. There won't be much contention with the abilities of 338wm and large toothsome beast here in NA.
Not much of an argument from me here, I feel the same way about my 338/06 as you do about the 9.3. Both darn good rounds and to my mind they'll do all that a good 338 will do.
Good comments.
