Metallic Cartridge Chamber Pressure Measurement

To this day, most published chamber pressure (MAP) data for metallic cartridges is taken by the copper crusher method of measurement. The proper name for this type of measurement is CUP, or Copper Units of Pressure. Another, similar, method uses lead crusher pellets and the resulting pressure values are called "Lead Units of Pressure," or LUP.

Chamber pressure - Wikipedia

Copper crusher method. Through the mid-1960s, the most common way of measuring pressure was drilling a hole through the chamber of the barrel and inserting a copper slug that fit flush with the chamber walls. When a cartridge is fired, it compresses the copper slug. It is then removed, measured, and compared to the original dimensions.

8 MIL (.008 inches thick) 32 gauge: The 8 mil copper is approximately 11 - 12 times thicker than typical aluminum foil and 1.5 times thicker than the 5 mil. This is a heavy-duty tooling foil. 8 mil can be cut fairly easily with scissors and is still very pliable. It may hold shape a little better than the 5 MIL, but will not bear much weight and will yield to increasing pressure.
