More DetailsThe old method of pressure measuring was the copper crusher or lead in some from FIREARM TECHNOLOGY BBS 100 at Sonoran Desert School
More DetailsIn this method, the test barrel is placed over the cartridge case and a steel piston touches the case. A soft copper rod (crusher) sits atop the piston and is restrained by an anvil. When the cartridge fires, pressure pierces the case and drives the piston into the copper crusher. This force shortens the crusher and the length is measured.

More Details· Without measuring each cartridge at the base, you''ll never read the correct peak pressure. The other fact, which I think is the main problem, is that the deformation of the crusher gauge is a record of the total force on the gauge over the entire internal ballistic cycle, not just a measure …

The indentation must measure 0.014 inch (read to the nearest 0.0005 inch) with only a 0.001-inch variation to indicate a passing indentation test. Copper Used in the Crusher Both variations of the copper-crusher measuring system (to
More DetailsThe amount of this deformation is then precisely measured and a very standardized indication of pressure is determined. To this day, most published chamber pressure (MAP) data for metallic cartridges is taken by the copper crusher method of measurement. The proper name for this type of measurement is CUP, or Copper Units of Pressure.

The copper crusher gauge holder has a circular aluminum upper plate and a circular aluminum lower plate having a layer of urethane rubber approximately 34 inch thick sandwiched between the plates. The gauge holder is bored to hold copper crusher gauges and center-bored to fit over a ...
More Details· The difference in crusher length before and after firing is then converted mathematically to a pressure range, in units of CUP or LUP (copper units of pressure or lead units of pressure). Copper crushers are generally either .146 in diameter and .400 long to start with, or .225 in …

More DetailsThe piezoelectric transducers and the copper crusher gauge can be installed in the same mounting position in respect to barrel length but displaced by 90 degrees to each other. The copper crusher gauge had a nominal height of 4.91 mm and a nominal diameter of 3.0 mm. Figure 2. Transducers and crusher installation Figure 3. Copper crusher gauge ...
More DetailsCopper crusher method. Through the mid-1960s, the most common way of measuring pressure was drilling a hole through the chamber of the barrel and inserting a copper slug that fit flush with the chamber walls. When a cartridge is fired, it compresses the copper slug. It is then removed, measured, and compared to the original dimensions.

More Details· 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.
