I don't know why some think 62,000psi is too high for Africa or hot climates anywhere - .270Win, 7mm and .300 mags all of them - Weatherby ctgs. - all run 62,000 to 63,000psi as well as the .416 Taylor andother wildcats - 63,000psi - no problem with correct powders. Even my daughters .260 and my .375 IMP, 9.3x62- they all run 63,000psi - normal pressure. I guess if you say 50,000 to 55,000CUP or CIP, it sounds better.
It almost makes one wonder how the much beloved .375 H&H with its heralded modern performance could ever be used in Africa or any other hot climate environment considering its SAAMI’ 62,000 psi rating...guess they’d rather hear the 53,000 cup rating instead and think that it’s a low pressure cartridge.
