Copper units of pressure or CUP, and the related lead units of pressure or LUP, are terms applied to pressure measurements used in the field of internal ballistics for the estimation of chamber pressures in firearms. These terms were adopted by convention to indicate that the pressure values were measured by copper crusher and lead crusher gauges respectively. In recent years, they have been replaced by the adoption of more modern piezoelectricpressure gauges that more accurately measure chamber pressur
Ballistic Pressure Sensor Reference Guide. In this pressure measurement system a small hole is drilled through one wall of the case in line with the piston hole generally at midcase location the gas check piston and copper crusher are installed and retained with the thumb screw when fired the gases vent out through the drilled hole and expand the
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. Another, similar, method uses lead crusher pellets and the resulting pressure values are called "Lead Units of Pressure," or LUP.
copper crusher edit . Copper Crusher Method [ edit ] Through the mid-1960s the most common way of measuring pressure was drilling a hole through the chamber of the barrel and inserting a copper slug that fit flush with the chamber walls When a cartridge is fired it compresses the copper slug It is then removed measured and compared to the original dimensions

Copper Crusher Method. Through the mid-1960s, the most common way of measuring pressure was drilling a hole through the chamber of the barrel and inserting a copper slug that fit flush with the chamber walls. When a cartridge is fired, it compresses the copper slug. It is then removed, measured, and compared to the original dimensions.
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.
