The L.E. Wilson 6 XC case gage is a precision measuring tool built for reloaders who demand accurate headspace control and brass longevity. This one-piece gage lets you check fired cases quickly and reliably—a critical step before resizing that too many handloaders skip or get wrong. Oversizing brass is one of the most common reloading mistakes, and it kills case life fast. With this gage and a caliper, you can verify both overall length (to flag cases needing trimming) and datum-to-head length (to confirm proper headspace and prevent dangerous oversizing during the resizing stroke).
Proper headspace control starts at the press, and that means setting up your full-length resizing die correctly. The L.E. Wilson gage gives you the reference point to dial in your die so it sizes only what needs sizing—protecting your brass investment and ensuring safer, more consistent loads. The tool features a knurled middle section for a secure grip and is built to the tight tolerances Wilson is known for.
Whether you're a precision rifle shooter stretching brass life across dozens of reloads or a high-volume hunter looking to avoid premature case failure, this gage belongs in your reloading bench. It's straightforward to use, requires no setup, and works with your existing calipers and headspace tools.

Frequently Asked Questions
What cartridge does the L.E. Wilson 6 XC case gage fit?
This gage is designed for the 6 XC cartridge. The .473" large end ID and .347" small end ID dimensions are calibrated for 6 XC brass.
How do I use this gage to set up my resizing die?
Insert fired cases into the gage and measure them with a caliper at the datum line and from the case head. This tells you how much the case needs resizing. Adjust your full-length die so it reduces the case to the correct headspace without unnecessary oversizing.
Will this gage work with my digital caliper?
Yes. The gage works with any standard caliper—dial, vernier, or digital. The large and small end IDs provide reference surfaces for measuring overall length and headspace dimensions.
What comes in the box?
The package includes the case gage and instruction sheet, shipped in a cardboard box.
