.308 Winchester vs. 7.62x51mm NATO | The High Road

May 22, 2008 · In the 1960s, SAAMI and the reloading industry got together and agreed to list PSI values measured by the copper gauge as CUP. The US military standards predate this agreement and the military doesn't care, so they just list the pressure as PSI without indicating that it is a copper crusher .

Internal Ballistics

This method has been largely superseded by piezo-electric and strain gauge units which replace the copper slug with a crystal or strain gauge which changes its electrical properties in response to pressure or dimensional changes. Such measurements are stated in PSI. For low pressures a lead crusher can be used and measurements are in LUP.

Copper crushers - dynamic calibration in the laboratory

Copper crusher gauges are the traditional means to routinely determine peak pressures in large caliber weapons. Most attractive in this method is its simplicity in use. Questionable is the precision in reading the pressure in view of the cumbersome gauge calibration practice which is prone to errors, especially in the low temperature regime.

Cartridge Pressure Standards - kwk

Vieille in France, who developed the first military smokeless powder, also "invented a rotating recording crusher gauge with which pressure could be measured as it varies with the time." I have no details on Vieille's crusher, but I've read he was the first to detect pressure waves inside the chamber.

CUP vs. PSI — What's The Difference in Pressure Measurements

Oct 13, 2014 · The other fact, which I think is the main problem, is that the deformation of the crusher gauge is a record of the total force on the gauge over the entire internal ballistic cycle, not just a measure of the peak. Cartridges may have the same peak pressure, but different cycle times, so the total force and hence gauge deformation varies.

A strain gauge is attached to the barrel just forward of the chamber. Upon firing, the barrel stretches briefly, and this stretch is measured by the gauge. This method is generally reserved as a way of relatively comparing different cartridge loads as the strain gauge reading is not as accurate as a copper crusher or Piezo test.

Metallic Cartridge Chamber Pressure Measurement

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.
