Because your safety is on the line Forster Headspace Gages are made with painstaking care and exacting manufacturing standards to ensure accurate testing of your rifles chamber. If a rifle closes on a GO gage the rifle chamber will accept any ammunition that is made within SAAMI (industry standard) specifications. If a rifle closes on a NOGO gage the rifle chamber might have excessive headspace. Most gunsmiths chamber a rifles headspace between the GO and NOGO dimensions. If a rifle closes on a FIELD gage the rifle chamber is dangerously close to or already over the SAAMI specified maximum chamber size.
