The L.E. Wilson 280 Remington case gage is an essential reloading tool for anyone working up ammunition in this classic magnum caliber. Whether you're fine-tuning a new load or maintaining quality control across multiple reloading sessions, this single-piece gage gives you a straightforward way to check fired cases and confirm proper headspace before resizing. It's the kind of simple but critical tool that separates careless reloading from safe, consistent ammunition.
Case gages serve two main functions: they let you verify overall case length (so you know when trimming is needed) and they measure datum-to-head length to ensure your resizing dies aren't oversizing the brass. Oversizing is one of the most common reloading mistakes, and it hammers case life. By catching it early with a gage and calipers, you'll get more reloads per case and more consistent performance down the line. For 280 Remington specifically, this tool fits the cartridge dimensions precisely, removing guesswork from the setup process.
The gage itself is a durable one-piece design with a knurled grip in the middle for easy handling at the bench. Its stepped design accommodates the shoulder and head dimensions of 280 Remington brass, and the small end (.347" ID) and large end (.473" ID) are sized to your cartridge. Pair it with a standard caliper and you've got a quick, repeatable way to verify headspace and case length without expensive equipment or complicated procedures.

Frequently Asked Questions
What's included with the L.E. Wilson 280 Remington case gage?
The gage comes with the tool itself and printed instructions. You'll need to supply your own caliper to take measurements.
How do I use a case gage to set up my resizing die?
Insert a fired case into the gage, then measure the distance from the head of the case to the shoulder using a caliper. This datum-to-head measurement tells you whether your resizing die is set correctly. Adjust the die height to keep brass from being oversized, which extends case life significantly.
Will this gage work with my fired 280 Remington brass?
Yes—the gage is dimensioned specifically for 280 Remington cases. The stepped design accommodates the shoulder and body diameter of this cartridge.
Do I need a caliper to use this gage?
Yes, a standard caliper is required to measure the distance between the case head and shoulder while the case is in the gage. This measurement ensures proper headspace and die setup.
