The L.E. Wilson Case Gage for 30-30 Winchester (brand part no. CG-3030) is a one-piece precision tool made in the USA by L.E. Wilson for checking fired brass before it goes back through a sizing die. It gives a single reading for both overall case length and headspace, so lever-gun reloaders can confirm their 30-30 brass is still within safe tolerances before the next load. It is compact enough for a range bag and simple enough to use on every case. Reloaders who shoot this classic cartridge regularly treat the check as a routine part of the process.
