Copper Unit of Pressure (CUP) Defined by Hodgdon « Daily

Apr 18, 2015· A: Copper Unit of Pressure (CUP) is a measurement used in the ammunition industry to determine the chamber pressure created by a cartridge load. Originally, a precisely formed copper slug was placed in a fixture over the chamber. When the cartridge was fired, the amount of crushing measured on the slug allowed engineers to determine the pressure.

REDESIGN OF COPPER CYLINDER USED FOR M4, M16, AND

primarily used to measure pressure for ammunition testing. To measure pressure, a copper crusher cylinder is compressed by a piston fitted to a piston hole into the chamber of the test barrel. Pressure generated by the burning propellant acts on the base of the piston, forcing the piston to move, thereby permanently compressing the copper cylinder.

.223 vs 5.56: The Ultimate Comparison & Review Gun Digest

Sep 12, 2012· The old way of measuring pressure was known as the copper crusher method. In it, a test barrel would have a hole drilled through it to a specified set of dimensions. Then, a little copper cylinder was clamped in place over the hole. When the round was fired, the copper cylinder got hit with the pressure and was compressed.

7.62 NATO vs. .308: Is There a Difference? The Armory Life

“The first 7.62×51 NATO pressures were retrieved by copper crusher. Current piezo-electric reads on .308 ammo are more precise and repeatable, often higher.” Popular in National Match competition, the .308 yields about 4½ inches to 10-mph wind at 600 yards. Jeff Hoffman at Black Hills Ammunition notes differences in measurement location.

Nonlinear Material Behavior Analysis under High

Gun chamber pressure is an important parameter in proofing of ammunition to ensure safety and reliability. It can be measured using copper crushers or piezoelectric sensor. Pressure calculations in copper crusher method are based on linear plastic deformation of copper after firing. However, crusher pressure deformation at high pressures deviates from the corresponding values measured by
