Where is a breech face mark located?

Breech face marks- These marks come from the area surrounding the firing pin of the gun. After the cartridge powder is ignited by the firing pin striking the primer cup, tremendous pressure is exerted in the chamber of the weapon, forcing the back of the cartridge case against the breech face of the weapon.

What is a breech block on a firearm?

: the block in breech-loading firearms that closes the rear of the barrel against the force of the charge and prevents gases from escaping.
