Thus a separate ‘No Go’ gauge is required for each different individual dimension. Gauge is a word that is used both as a noun as well as a verb as it refers to a scale of measurement and the act of measuring the quality or quantity of something. If a rifle closes on a FIELD gauge, its chamber is dangerously close to, or longer than, SAAMI’s specified maximum chamber size. Most gauge makers make it .006" longer than the min.
