Until the mid 1960's the only method commonly used for measuring chamber pressures was the copper crusher. Basically, a hole is drilled in the chamber of a firearm and a crusher chamber is attached to that hole. In this crusher chamber is placed a very precisely manufactured piece of copper. ... Strain gauge results are reasonably accurate but ...

The M-11 Copper Crusher Gage is a device which measures peak pressure developed in the chamber of large caliber weapons. This gage is one of two models used by the U.S. …

A copper crusher is a type of pressure gauge that is used in firearms to measure the pressure of a cartridge during firing. The copper crusher works by measuring the deformation of a copper ...

The copper crusher is a mechanical procedure in which a test . barrel is modified to contain a small piston installed over a . ... Twelve (12) gauge . is the most common, followed by 20 gauge, 16 gauge, .410, 10 gauge, and 28 gauge. Note that .410 is technically not a gauge size. All shot shells are centerfire cartridges. 11.

The US military uses the copper crusher gauge for 7.62 NATO standards, which is 50,000 PSI (CUP). They don't follow the convention because they don't care.

April 18th, 2015. Copper Unit of Pressure (CUP) Defined by Hodgdon. When you look at a loading manual with load data, you will usually see pressure ratings for stated load. Sometimes these are listed in PSI …

To measure pressure, the copper-crusher method uses a test barrel, gas check, piston and copper crusher cylinder. Above, right, is a close-up of an assembled gas check, piston and copper crusher. ...

Copper crusher gauges are the traditional means to routinely determine peak pressures in large caliber weapons. Most attractive in this method is its simplicity in use. Questionable is the precision in reading the pressure in view of the cumbersome gauge calibration practice which is prone to errors, especially in the low temperature regime.

The M-11 Copper Crusher Gage is a totally self contained unit, which is basically cylindrical in shape with steel parts fabricated from 300 grade maraging steel. It measures 38 mm (1.50 in.) in length and 19 mm (0.75 in.) in diameter. The gage consists of a body, cap, and other inner working components as shown in Figure 1.

This study examined the operation of a pressure gauge for measuring the internal pressure of a barrel. During the ammunition performance evaluation test, the internal pressure of the barrel was measured mainly using a copper crusher gauge. The internal piezo gauge (IPG) was used to replace the pressure measurement method, and the test results were …

A pressure-measuring device called the electronic crusher gauge is described. The volume of the gauge is small enough (38 cm/sup 3/) that it can be placed in the powder chamber of large- or medium-caliber guns, with chamber volume not less than 4 dm/sup 3/. The gauge is characterized by digital data recorded with a sampling frequency from 0.1 …
