One piece gauge that will check overall length to indicate the need for trimming, datum to head length to assure correct headspace and to prevent over sizing. Available for most popular rimless cases. The Cartridge Case Gage was designed with safety in mind and was invented by our founder Sam (L.E.) Wilson in 1935 after a fellow shooter approached him for help in solving a case-separation issue. The gauge allows you to see just how much you are sizing back your shoulder on your cases.
This is best done by following the steps below.
  • Measure a case in AS-FIRED condition. Note headspace measurement
  • Resize case on current die setting
  • Then place back in the gauge to see just how much you are sizing the shoulder back. This can be measured by using the Case Gage Depth Micrometer
  • Finally, adjust sizing die accordingly to desired shoulder set back.

After sizing your cases, there is a good chance the brass will lengthen. The gauge will also check min/max case length and will point out the need for case trimming. This is an essential tool for every reloader.

Also see the Wilson Case Gauge micrometer top and base block to fit onto this tool. (Separate purchase). This additional tool make the measuring job much easier and the one micrometer unit can be used on several different Wilson Case Gauges. https://www.brtshooterssupply.com.au/product/wilson-case-gauge-depth-micrometer/

Note: Does not measure body diameters. This gage is intended to be used with fired cases to determine a basis for full length sizing and trimming.
