The L.E. Wilson 25-06 Remington case gage is a one-piece headspace and length measuring tool built for reloaders who want to dial in their full-length resizing dies with precision. Whether you're handloading for a high-velocity varmint cartridge or a long-range hunting round, this gage helps you verify that your brass hasn't been oversized during the resizing process—a mistake that costs case life and creates safety risk. It's the kind of tool that separates careful handloaders from those who guess.
Using a case gage and caliper together, you can quickly measure the fired case's headspace and confirm overall length to identify when trimming is needed. This routine check catches problems before they compound. The L.E. Wilson gage is designed to work with standard 7/8"-14 press-type full-length resizing dies, making it a natural fit into an established reloading workflow. The single-piece construction is simple, durable, and straightforward to use—no adjustments, no complications.
Built with a knurled grip in the middle for comfortable handling, the gage features a large end (that seats the case shoulder) and a small end (for datum line reference). It arrives with instructions and ships in a cardboard box, ready to go into your reloading bench or range bag alongside your calipers and sizing equipment.

Frequently Asked Questions
What is a case gage used for in handloading?
A case gage measures headspace and overall length of fired brass. It helps you confirm that your full-length resizing die is adjusted correctly and that brass hasn't been oversized during the resizing process. Combined with a caliper, it ensures consistent, safe ammunition while extending case life.
What dies does the L.E. Wilson 25-06 Remington case gage work with?
This gage is designed for use with 7/8"-14 press-type full-length resizing dies, the standard thread size for most reloading presses.
Do I need a separate measuring tool to use this gage?
Yes, you'll need a caliper to measure the dimensions of your fired cases against the gage. The gage itself serves as the reference standard; the caliper provides the measurement reading.
Is this gage suitable for belted magnum cartridges?
This is a regular, non-adjustable gage. L.E. Wilson makes an adjustable-style gage specifically for belted magnum cases, which require special handling to preserve case life. Check your cartridge type before ordering.
