What is the edge on the base of a cartridge case that stops the progress of the case into the chamber?

Explanation:
The edge is the rim. The rim is a raised circle around the base of the cartridge case. It sits against the breech face and is engaged by the extractor when the round is chambered. That rim provides a positive stop, so the cartridge cannot be pushed further into the chamber, which helps establish proper headspace and ensures reliable chambering and extraction. The other parts—case (the container), bullet (the projectile), and primer (the ignition source)—have other roles, but they do not function as the stopping edge.
