The Lyman Pro Maximum Cartridge Gauge for .40 S&W is a precision inspection tool built for reloaders who refuse to compromise on ammunition quality. Whether you're loading for competition, duty carry, or the range, this stainless steel gauge lets you verify critical dimensions before you fire a round—case length, case diameter, and overall cartridge length—giving you the confidence that comes with a properly built cartridge.
Competitive shooters and serious handloaders have made cartridge gauging a non-negotiable step in their reloading process. Lyman's Pro Maximum line delivers the precision and durability required for that level of scrutiny. Machined from corrosion-resistant stainless steel, this gauge resists rust and wear through years of use. The knurled exterior flats prevent the tool from rolling on your bench, while the integrated o-rings grip your hand without slipping—practical details that matter when you're checking dozens or hundreds of rounds.
This is the kind of tool that separates meticulous reloaders from casual ones. It's not glamorous, but it's exactly what you need to catch dimensional problems before they become reliability problems. If you're serious about your handloads, the Pro Maximum Gauge belongs in your reloading setup.
