The 14.5×114mm has 42.53 ml (655 [[grain (measure)|grains]] H<sub>2</sub>O) cartridge case capacity. The exterior shape of the case was designed to promote reliable case feeding and extraction in [[bolt action]] rifles and [[machine guns]] alike, under extreme conditions. | The 14.5×114mm has 42.53 ml (655 [[grain (measure)|grains]] H<sub>2</sub>O) cartridge case capacity.

According to the official guidelines the 14.5×114 case can handle up to 360 MPa (52,213 psi) piezo pressure. In [[C.I.P.]] regulated countries every rifle cartridge combo has to be [[Proof|proofed]] at 125% of this maximum C.I.P. pressure to certify for sale to consumers. | According to the official guidelines the 14.5×114 case can handle up to 360 MPa (52,213 psi) piezo pressure.
