WebFor example, the SAAMI maximum pressure for the 7.62 x 51 mm is given as 52000 psi (CUP), or 62000 psi (430 MPa); the .45-70, on the other extreme, is listed as 28000 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). WebSAAMI Standards Development and Maintenance Procedure – The purpose of this Procedure is to establish a uniform process that is accredited by the American National Standards Institute (ANSI) for of the development and maintenance of American National Standard (ANS) by Sporting Arms and Ammunition Manufactures’ Institute, Inc. (“SAAMI”).

WebJan 7, 2024 · PSI measures just the peak of the pressure curve. Two loads that have exactly the same PSI can have drastically different CUP measurements if the powders are different burn speeds. The faster powder will have a lower CUP and the slower powder will have a higher CUP. CUP is a better predicter of velocity than PSI. WebMar 10, 2024 · For example, our .30-’06 has a copper-crusher pressure MAP of 50,000 CUP and a piezo pressure MAP of 60,000 psi. An alignment fixture holds the conformal piezo transducer in the chamber port while the cartridge is fired through the test barrel. Piezoelectric Method burley shocks for harley road king

In 1896, the .32 S&W Long was introduced, which generated slightly higher velocities. The introduction of the .32 H&R increased pressures from 15,000 psi to 21,000 CUP, giving velocities of approximately 1,200 ft/s (370 m/s). halo mounting frame installation
