Forster Headspace Go 303 British u224 Shock ResistantEvery gunsmith knows that proper use of a headspace gauge 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 rocket exhaust.
