Area 419 Headspace & Ogive Measurement Kit

The Area 419 Headspace & Ogive Measurement Kit includes all sizes of headspace gauges, all bullet ogive gauges, and the gauge body, anvil and storage tray. To make these measurement gauges, they all needed to be the same. Exactly the same. And they had to stay that way. All of these parts are made on world-class DMG Mori lathes, from American steel, cut with reamers for consistency, and then nitrided to help them last a lifetime. Headspace gauges don’t need the be complicated, they just need to be correct, and exceedingly consistent. This led Area 419 to use a traditional datum-style gauge – as they believe it provides the most true measurement – cut with a reamer to keep the diameter, face, and radius as consistent as possible. Again, this is in an effort to allow you to compare your measurements with someone from North Dakota or Nevada or the Netherlands, knowing that the numbers on your caliper mean something. While most ogive comparators work on a standard datum measurement, like the headspace gauges, Area 419 engineers thought there was a much more appropriate way to measure the ogive of a bullet. They have designed and are using custom tooling that allows them to replicate the lead area of your barrel’s chamber (if it has the standard 1.5* lead). The goal here is to allow you to measure seating depth and jump the only way that it matters, and that’s relative to your chamber. This will reduce the large swings in gauge readings from one projectile class to another, allowing you to see what really matters. Note: These kits were designed to work with Mitutoyo calipers, but do not include them. Other calipers may fit, but are not guaranteed.
