  • Rimfire Firing Pin Indent Copper Crusher (part 1) 2017

    The difference in crusher bar length before and after firing is measured and then converted mathematically to a pressure, in units of CUP (copper units of pressure). It is important to realize that CUP cannot be interchanged with another common unit of pressure, namely pounds per square inch (PSI).
