CNPG - Manual 2018-06-05 CNPG / Vers. 1.0 CS Shooting Performance
This manual describes the CNPG, a caliber measuring system from CS Shooting Performance that measures the neck wall thickness of cartridge cases with a dial gauge. It explains why a constant and symmetrical neck wall thickness matters for accurate shooting performance, listing benefits such as better concentricity between bullet and case, smaller muzzle velocity differences between shots, and cases that can be reloaded more often.
The document covers the components of the gauge (dial gauge with 1/1000 mm reading, hardened centering bolt, mushroom-shaped ball, caliper baseplate, system carrier and rotable casing ring), the measuring process step by step, an application example for reading wall thickness differences, and how reloaders who turn their cases can check the effective neck wall thickness.

Questions answered in CS Shooting Performance manuals
How do I measure the neck wall thickness with the CNPG?
Put the case neck between the centering bolt and the ball taster, first turning the ring of the gauge to the 0 position, then read the deflection of the pointer while turning the case in small angle steps.
