We ran tests on blowing up rifles (in a blow up chamber). There is or was back in 1969, a big difference on what different pressures different manufacturer's rifle would take.
Blowing up rifles was one thing, escaping gases that would shoot back into the shooters face was another. At that time all rifles were not equal in that regard also, I believe that they still are not.
If I were interested in getting the highest velocity (highest pressure) out of a certain cartridge I certainly would be choosy on which manufacturer's rifle I'd use.
But that isn't me! If I want more velocity, I use a larger cartridge.
The other thing I'd like to add about high pressure is temperature sensitive powders. I've had real bad luck with some powders in heat after developing in mild temperatures. High temperature with heat sensitive powder can cause blown primers, gases in the shooters face and damaged rifles.
