Lyman Pro Headspace Features The Lyman Pro Headspace Gauge for 6.5 Creedmoor is precision machined from corrosion-resistant stainless steel giving it a long service life free from rust even with regular handling and storage. Flat sides machined into the body of the gauge prevent it from rolling off a reloading bench a small but meaningful detail for a tool that is used repeatedly during die setup. An integrated O-ring provides a secure non-slip grip making the gauge easier to hold steady while taking a measurement. These design touches echo the features found in Lyman s well-regarded Pro Die Sets bringing that same attention to usability to a standalone measuring tool. This gauge is built to check both maximum and minimum cartridge headspace in addition to maximum case length all for the .264 diameter 6.5 Creedmoor cartridge. Headspace gauges like this one are recommended any time a reloader is setting up sizing dies for a bottle neck cartridge since improper headspace can lead to chambering issues or excessive case stretching. Taking accurate headspace measurements helps extend brass life and improves the safety and consistency of reloaded ammunition. For 6.5 Creedmoor reloaders who want a durable precise tool for dialing in their sizing dies the Lyman Pro Headspace Gauge is a dependable addition to the reloading bench.
