The test cartridge must be inserted into the chamber in such a way that the hole in the test cartridge case lines up with a gas port hole that channels the gas pressure from the cartridge case to the face of the sensor. The measurement accuracy of the pressure measurements with 21st century high-pressure sensors is expected to be ≤ 2%. [7]
The C.I.P. almost exclusively uses one type of Piezoelectric sensor (called a "channel sensor") made by the Swiss company Kistler [13] [14] or the Austrian-made HPi GP6 that both require drilling of the cartridge case before firing the proofing cartridge in a specially made test barrel.

In cartridges, the cannelure is a band pressed into the case which helps prevent cartridge setback when the case mouth is properly crimped onto the cannelure. [4] Bullet setback of .1" can increase pressure beyond safe limits and possibly cause a catastrophic failure.
The .460 Rowland / 11.43×24mm is a rimless, straight walled handgun cartridge designed in 1997 [1] by Johnny Rowland and developed in conjunction with Clark Custom Guns as a derivative of the .45 ACP [2] with the goal of producing a cartridge which can achieve true .44 Magnum [3] ballistic performance and be fired from a semi-automatic platform.
