Cartridge Pressure Standards
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 "LUP."

Old SAAMI Specs for pistol ammo??
All now use piezoelectric pressure transducers, but the methods of use differ. So firing of identical rounds of ammunition using those three methods will produce three numerically different pressure results. It is doubtful if any halfway modern ammunition manufacturer on Earth still uses the old copper crusher pressure measurement method.

The non-linearity in the copper crusher readings is just starting to show at around that pressure. For example, the 45-70 is rated at both 28,000 CUP and 28,000 psi because, in that chamber, at that pressure range, the two measure the same.

Copper Unit of Pressure (CUP) Defined by Hodgdon
A: Copper Unit of Pressure (CUP) is a measurement used in the ammunition industry to determine the chamber pressure created by a cartridge load. Originally, a precisely formed copper slug was placed in a fixture over the chamber. When the cartridge was fired, the amount of crushing measured on the slug allowed engineers to determine the pressure.
