The SAAMI (voluntary) Maximum Average Pressure (MAP) for this cartridge is piezo pressure or (37,000 CUP). This is considerably lower than the C.I.P. pressure limit and is done for liability reasons, in case a 7.92×57mm Mauser "S-bore" cartridge is fired in an "I-bore" rifle that has a narrower throat and barrel diameter. Most European ammunition manufacturers load to a lower C.I.P. pressure limit - Pmax piezo pressure for the 8×57mm I civilian "Patrone 88" offspring - for I-bore cartridges and use diameter projectiles; while the US based manufacturer Hornady followed their lead in their (now discontinued) EuroSpec brand 8×57 JS load.
