The Area 419 Zero Headspace and Ogive Measurement Gauge Kit is a precision reloading tool engineered for handloaders who demand accuracy and repeatability. Built on world-class DMG Mori lathes from American steel, each gauge is cut with reamers for maximum consistency and then nitrided to ensure a lifetime of reliable use. The kit includes all headspace gauge sizes, all bullet ogive gauges, the gauge body, anvil, and a custom storage tray - giving serious reloaders everything they need to measure seating depth and headspace with true, repeatable precision. Whether you are comparing loads with fellow shooters across the country or fine-tuning performance at the bench, the ZERO measurement gauges ensure your caliper readings always mean something concrete.
The headspace gauges use a traditional datum-style design cut with a reamer for consistent diameter, face, and radius measurements. The ogive gauges take an even more refined approach, utilizing custom tooling that replicates the lead area of your barrel chamber (based on the standard 1.5-degree lead), so you can measure seating depth and jump relative to your actual chamber. This dramatically reduces gauge-reading variation between different projectile classes. Note: These kits are designed to work with Mitutoyo calipers, which are not included. Other calipers may fit but are not guaranteed.
