Thanks, Phil. That is basically what I recalled--and have experienced!
Haven't used the 9,3x62 much in Alaska, just on a couple of bear hunts--though one of them was was with the 9.3 Barsness-Sisk wildcat, which was designed to get the same ballistics in a short-action case.
But have plenty of experience with both the "modern loaded" 9.3x62 and 375 H&H in Africa, and also some in the Lower 48, with a wider variety of bullets. So far still haven't been able to discern any difference in field performance.
