Gun Head Space Problems

Seeing stretch marks on shell casings or shell casings tear near the bottom of the shell casing (called the head). If you are reloading check to make sure that you are sizing the shell cases appropriately.  If the shell casing is sized to low it will create false head space problems. Guns over time have the locking lugs wear as well as the bolt flatten. When this happens the gun needs service and to have the barrel set back. It is then checked with a "Go" and "No Go" gauge by the gun smith and the gun is safe to shoot again. In an emergency (like a war but under no other circumstance)  using a gun with head space problems just neck size the shell casings that were last shot in the gun and load the gun with a lighter powder charge.  Richard W Norman

If they pass laws against guns then you will either make your supplies at home, salvage or do without.

They knew the public could not get a meter in an emergence so this was designed so anyone could build one with stuff you had around the house.3) US Ammunition Price list from 1912.
