Description
If you're loading for the 22 Hornet, this little gage from L.E. Wilson is one of those tools that earns its spot on the bench fast. It's a one-piece, precision-machined steel cylinder that lets you check both headspace and overall case length without any guesswork. Drop a fired or resized case in, and the milled step cutouts tell you whether your brass is sitting where it should be. That's it. No fiddling, no moving parts to drift out of spec.
What the 22 Hornet Case Gage Does on the Bench
The most valuable job this gage handles is setting up your full-length sizing die. One of the easiest mistakes in reloading is pushing the shoulder back too far, which stretches brass and shortens its life. By comparing an as-fired case against a resized one in the gage, you can see exactly how much you're bumping the shoulder and dial your die in for a setback of around .001 to .003 inches. Lay the gage flat on the bench and look across the top, and you'll also know whether a case has grown past max trim length and needs to go to the trimmer.
Why Reloaders Keep Reaching for the Wilson Case Gage
L.E. Wilson has been a family-run operation since 1927, and they produced the very first case gage back in 1935 after the founder was asked to help solve a case-separation problem. That heritage shows in the build. The gage checks against minimum SAAMI chamber dimensions, so you know your loaded rounds will chamber reliably and safely. It's made in the USA and built to hold tolerances over years of use.
Pairing Your 22 Hornet Gage With a Depth Micrometer
You can read this gage with calipers, a depth micrometer, or even feel the step with a fingernail in a pinch. For folks who want exact, repeatable shoulder-bump numbers, the gage drops right into the L.E. Wilson Case Gage Depth Micrometer, which fits all of their standard gages and reads in .001-inch increments. One note worth knowing up front: this gage checks headspace and length, not case body diameter.

Frequently Asked Questions
What does the L.E. Wilson 22 Hornet Case Gage actually measure?
It checks two things: headspace (the datum-to-head dimension) and overall case length for your 22 Hornet brass. Drop a fired or resized case in and the milled step cutouts show whether the case is within minimum and maximum spec. Keep in mind it does not measure case body diameter.
Do I need a micrometer or calipers to use this case gage?
Not strictly. You can get a quick read by feeling where the case head sits against the gage steps with your fingernail, which works fine for a go/no-go check. For precise shoulder-bump numbers you can use calipers, a depth micrometer, or the L.E. Wilson Case Gage Depth Micrometer, which drops right onto this gage and reads in .001-inch increments.
How do I use the 22 Hornet gage to set up my sizing die?
Measure a fired case in the gage and note where the head sits, then resize it and check again. The difference tells you how much you've pushed the shoulder back. Adjust your full-length die until you get a setback of roughly .001 to .003 inches, which keeps the case fitting your chamber without overworking the brass.
Is this the same as the L.E. Wilson 22 Hornet case trimmer holder?
No, they're two different tools. This is the case gage (CG-22HOR) for checking headspace and trim length. The trimmer case holder (CH-22HOR) is a separate piece that holds brass in a Wilson case trimmer for trimming, deburring, and reaming.
