L.E. Wilson Case Length Headspace Gauge Brass 223 Remington

L.E. Wilson .223 Remington Brass Case Gage. E. Wilson Brass Case Gage is precision machined from U.S. solid brass bar stock. This brass version is an upgrade to our standard steel line offering excellent corrosion resistance and a smooth surface finish ideal for consistent case measurement. This one-piece gage checks critical case dimensions including overall case length and datum-to-head length. These measurements indicate when trimming is required and help ensure correct headspace while preventing over-sizing during the reloading process. Originally designed with safety in mind the Cartridge Case Gage was invented by our founder Sam (L.E.) Wilson in 1935 after assisting a fellow shooter with a case-separation issue. The design allows reloaders to clearly see how much the shoulder is being set back during resizing. How to Use the Brass Case Gage Measure a case in its as-fired condition and note the headspace measurement Resize the case using your current die setting Place the resized case back into the gage to observe shoulder setback For precise measurement use the Case Gage Depth Micrometer Adjust your sizing die as needed to achieve the desired shoulder setback After resizing brass often lengthens. The Brass Case Gage also checks minimum and maximum case length helping identify when trimming is required. Note: This gage does not measure body diameters. It is intended for use with fired cases to establish a reliable baseline for full-length sizing and trimming. Package Contents: L.E. Wilson Brass Case Gage L.E.
