Lyman Pro Headspace Features The Lyman Pro Headspace gauge is precision machined from stainless steel a material choice that resists corrosion and keeps the gauge accurate through years of bench use. Its design is drawn directly from the Lyman Pro Die Sets giving reloaders a familiar feel and consistent build quality across their reloading tools. The outside flats are cut specifically to stop the gauge from rolling off the bench a small detail that saves time and frustration during a reloading session. Because it checks both maximum and minimum headspace on the same tool reloaders can dial in die adjustments with confidence rather than guessing at press settings. The o-ring fitted to the gauge body provides a non-slip grip so it stays steady in hand during repeated case checks without adding bulk to the tool. Checking maximum case length alongside headspace means a single gauge covers two of the most important measurements for safe reloading of bottle neck cartridges like .223 Rem. This dual-purpose function makes the Pro Headspace gauge especially useful when setting up a new sizing die or verifying an existing setup after a die change. For reloaders who want a durable accurate way to confirm their .223 Rem dies are set correctly the Lyman Pro Headspace gauge is a straightforward addition to the bench.
