    gun chamber pressure is an important parameter in proofing of ammunition to ensure safety and reliability. It can be measured using copper crushers or piezoelectric sensor. pressure calculations in copper crusher method are based on linear plastic deformation of copper after firing. however, crusher pressure deformation at high pressures deviates from the corresponding values measured by In the late a constantly repeatable means of measuring chamber pressure was devised. It depended on the use of copper or lead crusher rods. port was drilled through the chamber wall of a pressuretesting barrel, and a steel piston was placed in the port.
