Hello,

I want to cast my two cents after posting myself recently about this cartridge. An article I read suggested the hitch with the caliber is its 60,000 psi which is probably how they can get the velocity etc to match the 375 H and H if my understanding of ballistics is correct. For this reason it probably won't do so well in hotter climes where pressure concerns are very real.

What author wrote this nonsense? The pressure standards for the .375 H & H Magnum, both SAAMI and CIP, are 62,000 PSI. In other words, it's a HIGH pressure cartridge. Contrast that with the .375 H & H Flanged Magnum at 47,000 PSI. The Ultra Mags, Weatherby Mags, WSMs, etc., can run on up to 65,000 PSI but that isn't enough difference to spit at. To my knowledge, the pressure standard for the .375 Ruger hasn't been released yet, but it will be close enough to the .375 H & H to make no difference whatsoever.

The .375 Ruger isn't based on the 8X68S. The 8X68 has a base diameter of .522", while the new .375 Ruger uses a base diameter of .532".
