The L.E. Wilson 6.8mm Remington SPC case gage is a simple but essential tool for handloaders working with this intermediate rifle cartridge. Whether you're setting up a full-length resizing die or verifying that fired brass is within spec, this one-piece gage lets you catch the most common reloading mistake: oversizing. A quick check with calipers tells you if your cases need trimming and confirms headspace is correct—keeping your brass alive longer and your ammunition safe.
Reloaders who don't use a case gage often discover too late that their press is crushing brass or creating dangerous headspace issues. This tool removes guesswork by letting you measure both overall length and the critical distance from the datum line to the case head. It's the first step in a repeatable, accurate reload process and pays for itself in brass saved and ammunition reliability.
The gage is machined steel with a knurled grip section, designed to nest your fired or resized cases while you take measurements with standard calipers. It works with any reloading press and fits into any serious handloader's bench setup.

Frequently Asked Questions
How do I use a 6.8 SPC case gage?
Insert a fired or resized case into the gage, then use a set of calipers to measure from the small end of the gage to the headspace reference point on your case. This tells you the datum-to-head distance. Also measure the overall length of your case against the gage to see if trimming is needed. The instructions included with the gage walk you through the process.
Will this gage work with my reloading press?
Yes. The L.E. Wilson case gage is universal and works alongside any full-length resizing die and standard 7/8"-14 press setup. It's not a press tool itself—it's a standalone measurement device you use before, during, or after resizing to verify your die settings and case dimensions.
What's included in the box?
The package includes the case gage itself and printed instructions. You'll need your own calipers to take measurements.
Why is a case gage important for reloading?
Oversizing is one of the most common reloading errors and shortens case life dramatically. A case gage lets you set your resizing die correctly the first time and confirm that each batch of brass is within spec, preventing dangerous headspace issues and stretching that ruins cases prematurely.
