Until the mid 1960's the only method commonly used for measuring chamber pressures was the copper crusher. Basically, a hole is drilled in the chamber of a firearm and a crusher chamber is attached to that hole. In this crusher chamber is placed a very precisely manufactured piece of copper.
When the gun is fired the copper pellet is crushed (deformed) by the pressure to some degree. The amount of this deformation is then precisely measured and a very standardized indication of pressure is determined.
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.
