As John pointed out, the latest 'super magnum' revolver cartridges are really hot numbers. They run serious pressures, comparable to rifle cartridges (or beyond).
But, even .327 Federal Magnum, with it's "low" 45k psi, is considered to be a very high pressure revolver cartridge. (Just for comparison, even .44 Mag is considered 'high pressure' at 36k psi.)
