Pressures, Case Strength and Back Thrust
This copper unit of pressure is simply a description of how chamber pressure came to be gauged by use of a crusher gauge, invented by Alford Noble in about 1860. Small carefully controlled cylinders of soft metal, copper, called "crushers" are placed in a tool attached to the chamber area of a rifle barrel where a hole has been bored through ...

Copper units of pressure | Military Wiki | Fandom
Copper cylinders are used at high pressures, such as are generated by most handgun and rifle cartridges, and lead cylinders are used for low pressures such as are generated by shotgun shells. The crusher gun has a hole in the chamber that is linked to a piston, and upon firing, this piston is subjected to the pressure of firing.
