The Hornady Lock-N-Load Cartridge Gauge for 6mm ARC delivers precise headspace and case length measurements essential for consistent handloading results. This machined aluminum gauge eliminates guesswork in cartridge preparation, ensuring optimal chamber fit and reliable feeding in 6mm ARC firearms.
What Makes This Different
Unlike generic go/no-go gauges, the Lock-N-Load system provides exact measurements rather than simple pass/fail results. The precision-machined chamber replicates SAAMI specifications within 0.001 inches, allowing reloaders to identify case stretch, proper sizing, and optimal cartridge overall length. This level of accuracy translates directly to improved consistency and reduced pressure variations.Key Features
