Essential single-piece case gage checks overall length and headspace for 6mm/6.5 Creedmoor. Monitors shoulder setback during sizing and indicates when trimming is needed for safe, consistent reloads.
The Wilson Brass Case Gage for 6mm/6.5 Creedmoor is a precision instrument designed to take the guesswork out of case preparation. This single-piece gage has been the standard in reloading shops since its invention in 1935, when founder Sam Wilson created it to solve case-separation problems.
Headspace Control The gage allows you to measure and monitor headspace with precision, ensuring your cases are sized correctly to prevent dangerous pressure spikes and case failures.
Shoulder Setback Monitoring One of the gage's most valuable features is its ability to show exactly how much you're sizing the shoulder back with each pass through your sizing die. This direct feedback lets you dial in your dies for optimal performance.
Case Length Verification After sizing, brass often lengthens. The gage checks both minimum and maximum case length, alerting you when trimming is necessary to maintain safe, consistent ammunition.
This gage is designed for use with fired cases and does not measure body diameters. It provides the foundation for proper full-length sizing and case preparation.
For reloaders serious about safety and consistency, the Wilson Brass Case Gage is non-negotiable equipment.
