About MAP (CUP) and MAP (PSI): SAAMI publishes Maximum Average Pressure (MAP) using two different test methods. CUP values come from the legacy copper crusher system, while PSI values are measured with modern piezoelectric transducers. These methods are not directly interchangeable, and their values do not correlate numerically. A “—” value indicates that either Crusher or Piezo pressures were not established for that specific load. Always rely on the test method used for your cartridge’s official pressure rating.

Important: Pressure values shown are derived from publicly available data. Always verify chamber pressure limits, MAP values, and official test methods directly in the official SAAMI Centerfire Rifle Standard document. Consult SAAMI documentation before developing or modifying handloads. If you notice any information that appears incorrect or incomplete, please contact the support team so we can review and correct it promptly.
