Forster Headspace Go Gauge Belted Magnum, 300 Winchester Magnum, 7mm. Mounts The Mini Scabbard will accommodateEvery gunsmith knows that proper use of a headspace gage is the most reliable way to test the length of a rifle chamber. "Headspace" is the distance between the face of the breech and the base of the cartridge when the action is closed and excessive headspace can be dangerous as well as impair accuracy. For instance unsupported brass fired in a rifle action with excessive headspace can rupture allowing gas to blow rearward like a rocket exhaust.
