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

Apr 18, 2015· 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.

A (Very) Short Course in Internal Ballistics - Fr. Frog's Pad

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.

Chamber pressure - Wikipedia

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.

Metallic Cartridge Chamber Pressure Measurement

The amount of this deformation is then precisely measured and a very standardized indication of pressure is determined. To this day, most published chamber pressure (MAP) data for metallic cartridges is taken by the copper crusher method of measurement. The proper name for this type of measurement is CUP, or Copper Units of Pressure.
