Of course they do!

I asked my rhetorical question of beretz, about whether his 7mm Mashburn loads were put together with pressure-tested data, because the usual reason wildcats get very high velocities is pressures are higher than the maximum 65,000 PSI SAAMI allows with ANY cartridge.

This doesn't mean pressures above 65,000 PSI are unsafe (though SAAMI does prefer a little safety margin). But it means comparing wildcat velocities with factory-cartridge velocities usually involves a pressure advantage for the wildcat. The most accurate comparison would occur with both loaded to the same pressure.
