Forster .350 Legend SAAMI Dimensioned Go Length Rimless Headspace Gauge

Every gunsmith knows that the proper use of a headspace gage is the most reliable method to test the length of a rifle chamber. "Headspace" refers to the distance between the face of the breech and the base of the cartridge when the action is closed. Excessive headspace can be dangerous and impair accuracy. For example, unsupported brass fired in a rifle with excessive headspace can rupture, causing gas to blow rearward like rocket exhaust, which is a significant safety hazard. Forster Headspace Gages are crafted with meticulous care and stringent manufacturing standards to ensure precise testing of your rifle's chamber. If a rifle closes on a GO gage, it guarantees that the chamber will safely accept ammunition made within SAAMI (industry standard) specifications, ensuring both safety and optimal performance.
