The L.E. Wilson Pistol Max Gage 380 Auto is a precision case measurement tool built for reloaders who demand accuracy in every round they produce. If you're sizing and prepping .380 ACP brass, this gage gives you a straightforward way to verify that your cases meet spec before they go into the press—catching problems that can lead to unsafe loads or poor feeding. It's the kind of tool that separates careful reloaders from those who guess.
Overproduction of brass during full-length resizing is one of the most common mistakes in pistol reloading, and it's often invisible until a round fails to chamber. The Pistol Max Gage lets you spot that problem immediately by measuring the dimensions that matter: case mouth diameter, base diameter, rim thickness and diameter, and overall case length. Pair it with a digital or dial caliper, and you have a complete picture of whether your sized brass is in the safe zone or needs adjustment.
This is a no-fuss, no-batteries tool—just a solid gage body that works with any caliper you already own. It's particularly valuable when you're setting up a new die set or returning to loading after some time away; it removes the guesswork from establishing proper headspace and case dimensions. Whether you're prepping once-fired range brass or carefully maintained handloads, the Pistol Max Gage 380 Auto helps ensure consistency and safety every session.
