Bars are what the CIP Piezo system is given in. My understanding is they locate their transducer gas sampling point near the case mouth which causes it to be a couple thousand PSI lower than the SAAMI mid-web readings on the same cartridge in bottleneck rifle rounds. But you'd never know it looking at their numbers. Some are higher and some are lower than U.S. numbers. I agree these absolutes can have somewhat iffy value in determining what is safe in a particular gun. I think any of us who've been shooting for awhile have occasionally seen commercial or military ammo that was too hot, and much more often that was pretty lame, relative to safe potential for the cartridge. Mostly these measuring systems are useful in the industry for adjusting charges of different lots of non-canister grade powders to produce matching peak pressures, and to keep lawyers satisfied.
