Copper units of pressure - Wikipedia

For example, the SAAMI maximum pressure for the 7.62×51mm is given as 52,000 psi (CUP), or 62,000 psi (430 MPa); the.45-70, on the other extreme, is listed as 28,000 in both CUP and psi (190 MPa). SAAMI standards for a given cartridge may be expressed in CUP units, LUP units, or in standard units of pressure (psi or MPa).

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.

Metallic Cartridge Chamber Pressure Measurement

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 method is normally used for measuring relatively low chamber pressures, such as those generated by shotgun shells, while copper crushers (CUP) are used for measuring the pressure of handgun and rifle cartridges.

04-01-2011  Pressure against the piston shortens the crusher. We measure the crusher and consult a table of pressure values provided with each crusher lot. Starting at 0.499 inch, the table lists decreasing lengths in thousandths of an inch and, beside each length, the pressure in copper units of pressure (CUP) that it takes to shorten that much.

Copper crushers - dynamic calibration in the

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.

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.

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.

CUP, psi amp; Reloading Data - Shooting Times

04-01-2011  A copper crusher is placed on the upper end of the piston. Crushers are made to high material and dimensional standards, and each lot is calibrated to ensure consistent deformation. To provide the resistance that ensures the "crush" and captures the crusher, the pressure barrel has a heavy yoke--basically an inverted "U."

18-04-2015  Copper Unit of Pressure (CUP) Defined by Hodgdon. When you look at a loading manual with load data, you will usually see pressure ratings for stated load. Sometimes these are listed in PSI numbers, which most people correctly understand to be Pounds per Square Inch of pressure. However, powder-makers also commonly list pressure in CUP numbers.

Firearms History, Technology Development:

Therefore, when measurements are made using crusher gauges, the pressure is listed in mega-pascals (MPa - the SI standard unit of pressure) or pounds per square inch (psi - the imperial standard unit of pressure) followed by the letters CUP or LUP to indicate that the measurements were done using crusher

Bullet Ballistics 101: Pressure, Velocity Distance

Lead crushers (.325 x .500) typically register the low-pressure loads in rimfire guns and shotguns (though small-diameter copper crushers can be used too). Crushers are calibrated in a test press. Pounded by high pressures, crushers don’t register peak pressure accurately because the flow of copper is slower than the change of pressure in the chamber.
