L.E. Wilson
The L.E. Wilson 6.5mm Grendel case gage is an essential single-piece tool for reloaders who want to verify headspace and control case dimensions before they become a problem. Whether you're running a progressive or single-stage press, this gage lets you spot oversizing—one of the most common reloading mistakes—before fired brass gets damaged. By measuring headspace quickly and accurately with a caliper, you'll know exactly when your dies need adjustment and when cases need trimming, which extends brass life and keeps your ammunition safe and consistent.
Setting up your full-length resizing dies correctly is where a case gage earns its keep. The 6.5mm Grendel case gage checks both overall length and datum-to-head length in one go, giving you the data you need to dial in your 7/8"-14 press-type dies without guesswork. This one-piece design is straightforward and durable—no fussy adjustments or moving parts to wear out.
If you reload 6.5mm Grendel regularly, this tool pays for itself the first time it catches an oversized case or alerts you that trimming is due. Reloaders who skip the gage step often end up replacing brass prematurely or dealing with chambering problems. A few seconds with a gage and caliper at the bench beats troubleshooting at the range.
| Overall Length | 2.494" |
| Large End ID | 0.473" |
| Small End ID | 0.347" |
| Outside Diameter | 0.991" |
| Finish | Silver with knurled center grip |
| Includes | Gage and instruction card |
You'll need a dial or digital caliper to measure the gage when checking your brass. The gage itself and a caliper together give you the data to compare fired case dimensions against loaded specs.
Yes, this gage is designed specifically to help set up 7/8"-14 press-type full-length resizing dies. It lets you verify headspace and dial in your die height before running production.
This is manufactured for 6.5mm Grendel. The inside diameters and overall length are specific to that cartridge. L.E. Wilson makes separate gages for other calibers.
By catching oversizing early, you prevent work-hardening and premature cracking. Regular gage checks also let you trim cases right before they exceed maximum length, which keeps cases in service longer and maintains consistent headspace.
