    CUP vs. PSI — What’s The Difference in Pressure

    Oct 13, 2014 CUP Pressure Measurement The CUP system uses a copper crush cylinder which is compressed by a piston fitted to a piston hole into the chamber of the test barrel. Pressure generated by the burning propellant causes the piston to move and compress the copper cylinder. This will give it a specific measurable size that can be compared to a set

    Apr 01, 2010 These copper cylinders are actually made for the crusher method measurement of chamber pressure. When measuring percussion energy, the intention is to press the copper cylinder tightly against the weapon breech face. The firing pin impact causes an indent on the copper cylinder . The depth of the indent is then measured and the result used for
