Module 05 :: Pressure

When the cartridge fires, pressure pierces the case and drives the piston into the copper crusher. This force shortens the crusher and the length is measured. Postfiring lengths are compared to calibration tables accompanying each lot of crushers to find the pressure value for each shot.

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."

SAAMI pressure derating over time | The High Road

 · I believe the difference in pressures is due to better measuring equipment. Old copper crusher equipment did not measure pressure real time, and it did not measure peak pressure. Having bent several pre WW2 pistols, older guns are just not as hard or as strong as later stuff. I would not hot rod a 1930's, 40's, or 50's 357.

CUP - Copper Units of Pressure. In this pressure measuring technique a hole is drilled in the chamber and a piston fitted that presses on a calibrated copper slug (or crusher). (Some set ups also drill the cartridge case which changes the results compared to non-drilled cases.) The whole assembly is held in place with a yoke.

Copper Unit of Pressure (CUP) Defined by Hodgdon « Daily ...

 · 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.

It is then removed, measured, and compared to the original dimensions. Using the known properties of copper, the chamber pressure can then be calculated and expressed in copper units of pressure (CUP). While there are now more accurate methods of measuring chamber pressure, the copper crusher method is still used for verification purposes.
