peak pressure value to ensure a safe use of the weapon. Earlier, until the mid of the 1960s, the crusher gauge method, invented in 1860s by Nobel, was the only commonly used and standardized method for gas chamber pressure measurement [1]. A copper or lead cylinder is compressed by a piston fitted to a piston hole into the chamber of the barrel.

Because the indicated pressure from crushers is known to be off, SAAMI many decades ago began referring to the indicated pressure from their tests as "Copper Units of Pressure," a clumsy name commonly shortened to "CUP." For low pressure cartridges such as shotshells, lead is used for the crusher, and SAAMI refers to these numbers as …

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.
The first practical pressure gauge for measuring the pressure inside a gun was invented by Sir Alfred Nobel in the 1860s. 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
