Case capacity while giving an indication of the overall power potential of a cartridge it is most important to the ammunition reloader. While outside dimensions are rigidly controlled to industry specifications, the inside dimensions are easily influenced by construction differences between manufactures and can even change from lot to lot and from case to case in the same lot. Even though the outside dimensions might be similar, a cartridge made of thicker brass will have a smaller case capacity than one that has thinner brass. The cartridge with the smaller case capacity would show higher pressures when loaded with the same amount of powder than the cartridge with the thinner walls and thus larger capacity.
Case capacity can be found by filling the empty cartridge with water (leave the spent primer in the primer pocket) and then carefully weighing the water in the case.
