Accuracy One Concentricity Gauge
The Accuracy One Concentricity Gauge allows you to measure the runout of ammunition and ammunition components.
The Concentricity Gauge measures the internal and external neck runout of your cartridge case as well as seated bullet runout. It can also measure the runout of the ogive, bearing surface and boat-tail of individual bullets and can even measure your primer pocket runout.
Our Concentricity Gauge allows you to easily check the effectiveness of your reloading equipment. It also allows you to check and organize the quality of your factory-loaded ammunition. Starting the bullet straight into the barrel's rifling is essential for accurate shooting. The smallest improvements in your accuracy are worth every penny.
