Copper units of pressure - Wikipedia

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 In recent years, they have been replaced by

Copper Unit of Pressure (CUP) Defined by Hodgdon «

18/04/2015  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.

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. Lead is more easily deformed than copper, and the LUP

Rimfire Firing-Pin Indent Copper Crusher (part 1) 2017 ...

The copper crusher measures firing-pin load pressure using a solid bar machined of high-purity copper, from which the mini copper bars are sliced and machined to the exact size and shape of the many rimfire cartridge designs (e.g., short, long rifle, magnum). A single copper indent crusher is placed in the firing chamber of a firearm and the trigger is pulled, causing the firing pin to strike and leave an indent mark

1. Introduction - Hindawi

Copper crushers and piezoelectric sensor methods both have their pros and cons for chamber pressure measurement. Copper crusher technique is simple enough to obtain a rapid estimation of the peak pressure in ammunition testing but it has drawbacks for being of limited accuracy and only gives the peak pressure [3]. Similarly, for higher pressures the deformations noted are lower in comparison to that
