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 gage allows you to see just how much you are sizing back your shoulder on your cases. This is best done by measuring a case in AS-FIRED condition. Take a measurement. Then place back in the gage to see just how much you are sizing the shoulder back. Finally, adjust sizing die accordingly. After sizing your cases, there is a good chance the brass will lengthen. The gage will also check min/max case length and will point out the need for case trimming. This is an essential tool for every reloaded. Compatible calibers: 223 Remington/5.56 Nato.
