OK, but that rifle was built for 7X57, which has a max pressure of 56,565 psi.

Max pressure when?

The 173 grain 7mm Mauser Cartridges captured in Cuba, during the Spanish American war had a velocity of 2200 fps out of a 29 inch barrel. These are 40 K psia loads.

These were M1893 actions and that is the correct pressure levels for these older actions.
