The L.E. Wilson 300 Savage case gage is a precision measuring tool built for reloaders who want to dial in accurate headspace and avoid the costly mistake of over-sizing brass. This one-piece gage lets you check both overall case length and datum-to-head distance—the two measurements that tell you whether your fired cases are ready for resizing or need trimming first. If you're setting up 7/8"-14 press-type full-length resizing dies for 300 Savage ammunition, this gage belongs in your bench setup.
Headspace control is where case longevity lives. Too many reloaders jump straight to the sizing die without verifying their fired cases first, which leads to unnecessary work-hardening and premature case failure. A quick check with the L.E. Wilson gage and a caliper tells you exactly where you stand before you run a single piece of brass through the press. It's a small tool that prevents big mistakes.
Built from solid steel with a knurled grip section for control, the gage is designed to last through thousands of cases. The stepped bore accommodates the 300 Savage cartridge dimensions, and the straightforward one-piece design means there's nothing to adjust or maintain—just grab it, measure, and move on. Comes with instructions in a cardboard box.
| Product | L.E. Wilson 300 Savage Case Gage |
| Overall Length | 2.494" |

| Outside Diameter (OD) | .991" |
| Material | Steel with knurled grip |
| Finish | Silver |
| Included | Gage and instructions |
Insert a fired case into the gage—it will rest in the stepped bores. Use a caliper to measure the gap between the case shoulder and the gage's datum reference point to verify headspace, and check overall length against the gage to see if trimming is needed.
Over-sizing brass during the resizing process work-hardens the case and drastically shortens its life. By measuring headspace on fired cases first, you ensure your resizing die is set up correctly and you resize only as much as necessary.
Yes. This gage is designed specifically to help you set up 7/8"-14 press-type full-length resizing dies, allowing you to dial in the correct die height and ensure proper headspace control.
