L.E. Wilson 220 Swift Case Gage

The L.E. Wilson 220 Swift case gage is a precision reloading tool built to help you dial in your full-length resizing die setup and verify headspace on fired brass. For handloaders working with 220 Swift cartridges, proper headspace management and case length control are critical—they affect both rifle safety and brass longevity. This one-piece gage lets you quickly check overall length (to flag cases needing trim) and datum-to-head length (to confirm your resize die isn't over-sizing), helping you avoid the common mistake of crushing your brass with excessive die pressure.

L.E. Wilson gages are built to tight tolerances and designed to work with standard calipers for fast, repeatable measurements at the reloading bench. The 220 Swift gage dimensions are sized to your cartridge's specifications, and the knurled middle section gives you a solid grip during use. It's a simple, durable tool that doesn't rely on electronics or complicated setup—just a solid reference to keep your reloads within spec.

If you're serious about brass life and consistent, safe ammunition, a case gage belongs in your reloading kit. The L.E. Wilson 220 Swift gage is the kind of unglamorous tool that catches problems before they become disasters on the range or in the field.

Frequently Asked Questions

What is a case gage used for in reloading?

A case gage lets you measure headspace and overall case length quickly and accurately using a caliper. It's essential for setting up your full-length resizing die correctly and verifying that your fired brass isn't being over-sized during the resize process—both of which extend brass life and ensure safe, consistent ammunition.

How do I use the L.E. Wilson 220 Swift case gage?

Insert a fired case into the gage and use a caliper to measure from the head of the gage to the point where the case shoulder contacts the gage's datum line. Compare this measurement to your target headspace. You can also check overall case length against the gage's reference dimensions. The gage itself and the included instructions provide the reference geometry for your 220 Swift cartridge.

Why is this gage one-piece, and does that affect how I use it?

The one-piece design is durable and straightforward—it checks both overall length and datum-to-head distance without adjustments. Simply measure your fired cases against the gage reference. The knurled middle gives you a secure grip while you're measuring.

What's included with this gage?

The gage comes with the tool itself and printed instructions in a cardboard box. You'll need to supply your own caliper for measurements.
