Metallic Cartridge Chamber Pressure Measurement
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.

This gauge is commonly known as a "crusher gauge". To make a crusher gauge, drill a hole through the barrel into the chamber, fit the hole with a sliding piston, and let the sliding piston crush a small piece of lead against an anvil when the shot is fired. The higher the pressure, the more the lead cylinder is deformed. The crusher gauge is ...
