Now you no longer have to guess what gauge you are looking at. What is Headspace? In simple terms, headspace is the clearance allowed between the base of the cartridge case and the face of the bolt. Too little headspace and the bolt may not function correctly. Too much headspace may cause ruptured cases that can harm the gun and may cause personal injury and/or death. When purchasing a used firearm, it is very important to always check the headspace before firing it – especially surplus military rifles! Military surplus rifles have had thousands of rounds put through them and were often exposed to harsh use. You never know what kind of condition your gun may be in. It’s best to play it safe and check the headspace.
