OverviewCUP and LUP pressures vs. transducer pressuresMethodologyComparing unitsExternal links
Until the invention of measurement transducers in the 1960s, crusher guns were the only reliable method for estimating chamber pressures. With the availability of inexpensive, reliable transducers since the 1960s for actually making chamber pressure measurements, the industry almost universally has begun to move away from crusher guns for estimating chamber pressures, towards favoring making actual measurements. Transducers are also faster to use in practice, as they do not require the careful measu

Copper Unit of Pressure (CUP) Defined by Hodgdon « Daily
Apr 18, 2015· Copper Unit of Pressure (CUP) Defined by Hodgdon. 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. Replacement of copper crusher gauge (CUP) test equipment for
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.

crusher installed onto a pressure barrel. In this pressure measurement system, a small hole is drilled through one wall of the case in line with the piston hole, generally at mid-case location. The gas check, piston, and copper crusher are installed and retained with the thumb screw. When fired,
Differences in pressure measurement systems Shooters Forum
Jun 22, 2014· Only SAAMI segregates copper crusher and Piezo transducer results with different units (CUP and psi). Everyone else uses the same pressure units for both, be it psi, MPa, or bar (tenths of an MPa), and you just have to have the inside track on which instrument made the measurement to know what you are looking at.
Chamber pressure Wikipedia
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.

In the late 1850s, a constantly repeatable means of measuring chamber pressure was devised. It depended on the use of copper or lead “crusher” rods. A port was drilled through the chamber In the late 1850s, a constantly repeatable means of measuring chamber pressure was devised. It depended on the use of copper or lead “crusher” rods. A port was drilled through the chamber wall of a pressure‐testing barrel, and a steel piston was placed in the port.
