As has been said by others the 9.3x62 is NOT a 375H&H. But it is very nearly almost. I own rifles chambered for both cartridges and love both.

IMO the biggest thing that the 375H&H has going for it over the 9.3x62 is that, should you need to buy ammunition in far flung places, your more likely to be able to obtain cartridges for the 375 than the 9.3.
