The Hornady Lock-N-Load 40 S&W Cartridge Gauge is a precision-machined reloading tool that verifies proper case and ammunition dimensions against SAAMI chamber specifications. It checks both fired cases and completed cartridges, so handloaders can confirm that rounds will chamber correctly before heading to the range.

Built for reloaders who demand consistency and safety, the gauge serves as a dedicated quality-control step for every 40 S&W round produced at the bench.
