Internal Ballistics
Studying internal ballistics is all about accuracy—what accuracy is, where it comes from, and how the shooter can improve it. It's possible for the shooter to do something about accuracy problems once he or she understands the origins of their problems and takes the right steps to correct them.

Copper units of pressure | Military Wiki | Fandom
Copper units of pressure or CUP, and the related lead units of pressure or LUP, are terms applied to pressure measurements used in the field of internal ballistics for the estimation of chamber pressures in firearms.These terms were adopted by convention to indicate that the pressure values were measured by copper crusher and lead crusher gauges respectively.

Ammunition Pressure Testing
The copper crusher is placed on top of the piston and is trapped between the piston and an anvil attached to the test-barrel's receiver. When the round is fired, the pressure blows a hole in the side of the cartridge case, and the gas pressure drives the piston upward compressing the copper crusher cylinder between the piston and anvil.

commonly known as a "crusher gauge". To make a crusher gauge, drill a hole through the barrel into the chamber, fit the hole with a sliding piston, and let the sliding piston crush a small piece of lead against an anvil when the shot is fired. The higher the pressure, the more the lead cylinder is deformed. The crusher
