L.E. Wilson 270 WSM Case Gage

The L.E. Wilson 270 WSM Case Gage (part no. CG-27SM) is a go/no-go style gauge from L.E. Wilson that checks 270 WSM case length and headspace-critical dimensions against SAAMI reference specs after sizing or trimming. Handloaders use it on the bench after full-length sizing or trimming to confirm 270 WSM brass is within safe, reliable dimensions before loading and firing. It’s a straightforward quality check that catches undersized or oversized cases before they cause a chambering problem at the range or in competition.
