The Lyman Pro Headspace Gauges are engineered for precision and durability offering unmatched performance compared to the rest of the industry. Crafted from corrosion-resistant stainless steel these gauges are designed for a long-lasting rust-free experience. Inspired by our renowned Lyman Pro Die Sets the gauges feature flat sides to prevent rolling and O-rings for a secure non-slip grip. Designed to measure both maximum and minimum cartridge headspace as well as maximum case length these gauges are an essential tool when setting up sizing dies for bottle neck cartridges.
