L.E. Wilson Inc. 6mm/6.5 Creedmoor Case Gage

The Case Gage was designed with safety in mind and was invented by our founder Sam (L.E.) Wilson in 1935. 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.
