Availability: In Stock
The L.E. Wilson Case Gage 7mm WSM is a precision measuring tool built to help reloaders dial in safe, consistent headspace and avoid the common mistake of oversizing brass. Whether you're setting up a full-length resizing die or checking fired cases before their next reload cycle, this one-piece gage gives you the control you need to extend case life and maintain accuracy round after round.
Proper headspace is foundational to safe reloading, and this gage makes it simple: use it alongside a caliper to measure overall length (to flag cases needing trimming) and datum-to-head length (to confirm correct headspace and prevent over-resizing). For 7mm WSM shooters, getting this right means fewer split cases, better performance, and peace of mind at the bench. The tool itself is compact and durable—silver-finished steel with a knurled grip section for confident handling.
L.E. Wilson gages have been the reloader's choice for decades because they're straightforward, accurate, and built to last. If you're serious about brass management and die setup, this gage belongs in your reloading kit.
| Overall Length | 2.494" |
| Large End ID | .473" |
| Small End ID | .347" |
| Outside Diameter | .991" |
| Finish | Silver with knurled middle section |
| Includes | Gage and instructions |
Insert a fired case into the gage and measure the datum-to-head length with a caliper. Adjust your full-length resizing die until freshly resized cases match or fall slightly shorter than that measurement. This prevents over-resizing and preserves case life.
L.E. Wilson's one-piece design measures both overall length (to indicate trimming need) and datum-to-head length (to verify correct headspace) in a single, compact tool. It's designed for standard 7/8"-14 press-type dies and is calibrated specifically for the 7mm WSM cartridge.
Yes. Slide a fired case into the gage, then measure the distance from the small end of the gage to the head of the case using a standard or digital caliper to check headspace.
This is the regular-style gage. L.E. Wilson also makes an adjustable-style case gage designed for belted magnum cartridges. Confirm your cartridge type before ordering to ensure proper fit and function.
