Forster Products Sammi Dimensioned Headspace Gage, Rimless, Hardened Steel, Precision Ground, 350 Legend, GO

  • 350 LEGEND: Use to check headspace of 350 Legend..
  • RIMLESS CARTRIDGE HEADSPACE: The proper use of Headspace Gages 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..
  • GO: Corresponds to the minimum chamber dimensions. If a rifle closes on a GO gage, the chamber will accept ammunition that is made to SAAMI maximum specifications. The GO gage is essential for checking a newly-reamed chamber in order to ensure a tight, accurate, and safe chamber that will accept SAAMI maximum ammo..
  • 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 Gage 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 gage, and the gun’s actual chamber length , when the head of the cartridge is flush against the bolt face..
