Pressures in CUP are effectively useless. Some have PSI - it will be good when all are in PSI
 
CUP, BAR, etc, are confusing and less useful than PSI, but once you know the standard, CUP works just as well. And there is a very accurate conversion formula for PSI vs CUP.

Published pressures are just a guide, to keep you safe.

The interesting thing to me in this online data are the newer powders, like 4955, and Hybrid 100V.

They aren't useless, exactly, just the standard used by SAAMI at the time the cartridge was registered. There is a conversion that is about 93% accurate when dealing with hunting type cartridges. Multiply CUP by 1.516 and subtract 17902=PSI I tried it on a few cartridges and it was close.~Muir
