The L.E. Wilson 257 Roberts case gage is a precision measuring tool built to solve one of reloading's most common problems: oversized brass and improper headspace. Whether you're prepping once-fired ammunition or setting up your full-length resizing die, this gage lets you verify case dimensions quickly and accurately—using nothing more than your caliper and a few seconds of your time. It's the kind of simple, deliberate tool that separates careful reloaders from guesswork.
Correct headspace is the foundation of safe, consistent ammunition. Fired cases naturally grow; if you resize them back too aggressively, you accelerate case wear and shorten brass life dramatically. The L.E. Wilson 257 Roberts gage checks two critical dimensions: overall length (to flag cases needing trimming) and datum-to-head length (to confirm your resizing is doing exactly what it should, no more). This one-piece gage works with any dial or digital caliper, making it equally at home on a minimalist workbench or a fully equipped reloading room.
Built from solid material with knurling in the middle for a confident grip, the gage is compact and durable. It ships with instructions so you're never guessing how to use it. If you're running a 257 Roberts and you care about case longevity and ammunition quality, this is the kind of $20 decision that adds years to your brass and confidence to your loads.
| Overall Length | 2.494" |
| Large End ID | .473" |
| Small End ID | .347" |
| Outside Diameter | .991" |
| Finish | Silver with knurled center |
| Includes | Gage and instructions |
Insert the gage into the case mouth and slide it to the correct shoulder position. Then measure the distance from the gage's head end to the case head using your caliper. This datum-to-head measurement tells you whether your resizing die is set correctly. Compare your fired cases to the gage to verify you're not oversizing.
Fired cases naturally grow during firing. If your full-length resizing die removes too much material, you'll shorten the life of your brass significantly. The case gage ensures your die is set to do only what's necessary—restore the case to proper dimensions without excessive removal. This is especially important if you're reloading the same brass multiple times.
Yes. The gage also measures overall length, so you can quickly identify any cases that have grown beyond specification and need trimming before they're resized.
