The L.E. Wilson 32-20 Winchester case gage is a precision measuring tool designed for reloaders who want to verify proper headspace and overall case length before resizing. This one-piece gage works with standard dial or digital calipers to quickly check fired brass and help you avoid the common mistake of over-sizing during the resizing process. Whether you're setting up your 7/8"-14 press-type full length resizing dies or maintaining consistency across your brass inventory, this tool gives you the confidence that your ammunition is within spec.
Proper headspace control is essential for safe, consistent handloads and long case life. The L.E. Wilson gage measures both overall length (to flag cases needing trimming) and datum-to-head length (to ensure correct headspace). By catching out-of-spec brass before it goes back into the die, you'll reduce unnecessary work hardening and extend the useful life of your components—a real advantage if you're precision reloading for hunting rifles or benchrest applications.
Constructed as a single rigid piece with a knurled grip section, this gage is built to handle repeated use in the reloading room. The design is straightforward and reliable: no adjustments, no moving parts to wear. If you're serious about reloading 32-20 Winchester or simply want to raise your quality control standards, this is a practical addition to your bench setup.

Frequently Asked Questions
How do I use a case gage to set up my resizing dies?
Insert a fired case into the gage. Using a dial or digital caliper, measure the datum-to-head distance on the gage with the case seated. This reading tells you the headspace of your fired brass. When you adjust your full length resizing die, you'll resize fired cases to match this dimension, ensuring proper headspace without over-sizing.
Will this gage work for other cartridges?
This gage is designed specifically for 32-20 Winchester. L.E. Wilson manufactures gages for other calibers, so verify the cartridge marking on the tool matches your reloading application.
What comes in the box?
The package includes the case gage and printed instructions. You'll need to supply your own dial or digital caliper to take measurements.
Can I use this gage to check brass before I reload it?
Yes. The gage lets you measure both overall length (to identify cases that need trimming) and headspace dimensions on any fired case, fired or unfired, helping you maintain consistent ammunition quality.
