Abstract: A copper crusher gauge holder for testing internal pressures of cartridges during test firing is provided. The copper crusher gauge holder has a circular aluminum upper plate and a circular aluminum lower plate having a layer of urethane rubber approximately 3/4 inch thick sandwiched between the plates. The gauge holder is bored to hold copper crusher gauges and center-bored to fit over a cartridge centerline primer tube. A series of machine screws hold the plates together and allow for tightening the screws once the copper crusher gauge holder is in place in a cartridge to be tested. As the machine screws are tightened, the urethane rubber expands laterally gripping the inside of the cartridge and gripping the copper crusher gauges. A method to manufacture the gauge holder is provided.
