Forster Products 30-06 Springfield Rimless Headspace Gauge Set

Description: manufactures precision headspace gages to maximize safety and accuracy in your rifle. These gages are necessary when finish chambering a barrel, or when checking the chamber of a used gun to be sure the headspace dimensions are within safe limits. Machined from A2 tool steel, these gages are held to tolerances within 0.00015" to ensure accurate testing of your rifle's chamber. 30-06 SPRINGFIELD: Use to check headspace of 25-06, 6.5-06, 270 Win., 30-06, 8mm-06, 338-06, & 35 Whelen. RIMLESS CARTRIDGE HEADSPACE: The proper use of Headspace Gauges is the most reliable way to test rifle chamber length. Headspace in a rimless cartridge is the distance between the bolt face and a datum line, determined by SAAMI, where the front of the cartridge rests on its shoulder when the bolt is closed. NO-GO: Corresponds to the maximum headspace we recommend for gunsmiths’ chambering new bolt-action rifles. This is not a SAAMI-maximum measurement. If a rifle closes on a NO-GO Gauge, it may still be within SAAMI specifications, or it may have excessive headspace. To determine if there is excessive headspace, the chamber should then be checked with a FIELD Gauge. The NO-GO Gauge is a valuable tool for gunsmiths’ reaming new chambers, in order to ensure tight and accurate headspace PRECISION MACHINED: Manufactured from top-quality, hardened steel and precision ground to ANSI and SAAMI tolerances. Headspace tolerance ground to a very exacting ±.00015. Each Headspace Gauge thoroughly inspected with NIST-certified measurement tools to ensure the highest quality product. MEASURING MEANINGFUL HEADSPACE: Properly speaking, and for safety purposes, one measures “headspace” as the difference between the length of a standard cartridge, as represented by a Gauge, and the gun’s actual chamber length , when the head of the cartridge is flush against the bolt face.
