Metallic Cartridge Chamber Pressure Measurement
No method of measuring chamber pressure is accurate. If you measure 100 rounds of exactly the same load, in exactly the same gun, with exactly the same test equipment using the crusher method the measurements will typically vary plus or minus 5% from round to round. Some rounds may be off from the average for that group by 10% or more.

The difference in crusher length before and after firing is then converted mathematically to a pressure range, in units of CUP or LUP (copper units of pressure or lead units of pressure). Copper crushers are generally either .146 in diameter and .400 long to start with, or .225 in diameter and .500 long. Choice depends on application.

How do they measure cup pressure
Posts: 1,558. C.U.P is measured with a copper crusher. Basically it is a hole precisely drilled into the chamber of the test gun. The hole is there to accept a copper pellet that is measured before and after the cartridge is fired. The amount of difference in length of the copper pellet is used to calculate the pressure.

The accuracy class of a pressure gauge defines the permissible deviation of the display in percent of the full scale value. For plastic cases, this is 4 % or 2.5 %, whereas for chrome steel or stainless steel instruments it is 1.6 % or 1.0 %. For test gauges, the accuracy class is 0.6 %, 0.25 % or even 0.1 %, depending on the display range used.
