Cartridge Concentricity Gauge
As Featured in Glenn Zediker's Book "Hand Loading For Competition"

Proper mechanical analysis of cartridge cases and loaded ammo has a profound effect on accuracy. 20 years ago, the late Creighton Audette researched this out and found that one of the most critical factors in really good ammunition was truly concentric cartridge case walls measured just above the solid head of the cartridge case; about 1/2" on a .308 W case. The CCG Tool Measures this and 3 other critical dimensions.
