L.E. Wilson Case Length Headspace Gauge, 32-20 WCF
The Wilson Case Gauge is a one piece gage that will check the overall length of the cartridge case and indicate if the case is within min/max case length parameters.
It also measures min/max Headspace but does not measure body diameters. This gauge is intended to be used with fired cases to determine a basis for full length sizing and case trimming to the correct length.
