I began guiding in Alaska 43 years ago with a 375 H&H and decided to give the 9.3x62 a try almost 30 years ago.
I have killed a lot of big bears with both and "know" the 375 has to be a better killer. But I have seen no examples to prove it.

Anyone who claims the 30-06 is not effective has either not used one, or else is unwittingly commenting on their marksmanship.
