Ogive:
Ogive is the curved portion of a bullet ahead of the cylindrical, or shank, section. Also, the radius of this curve, usually expressed in calibers.
Our 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.
