All I'm saying, and I've done the profiles using 2 different ballistics software, is that the 9.3 X 62 is in the same ballpark as the 375 H&H, when each is loaded with the best NP available for each, barrel lengths equal.

www.bigbores.ca Could you post the pressure curves for each? I'm curious how a cartridge with less capacity, by almost 25%, can run with a larger capacity case given same barrel length and pressures.
The key to all miraculous velocities is always contained in the phrase "in my rifle". Physics usually don't apply when that phrase is utterred. I think the phrase is magic.
