After extracting the spent cartridge, what happens during the ejection step?

During the ejection step, the spent cartridge has already been extracted from the chamber, and at this point, it is propelled out of the firearm. This process is crucial for allowing a new cartridge to be loaded into the chamber for the next shot. Ejection ensures that the chamber is clear of any spent ammunition, preventing any possible jams or misfires.

The ejection step is a vital part of the firearm's cycling process, allowing for efficient operation and readiness for the next round. By successfully removing the spent cartridge from the chamber, this step sets the stage for the subsequent loading of a fresh cartridge, ensuring the firearm continues to function smoothly.

The other options do not accurately represent what happens during the ejection step, as the cartridge is neither being loaded into the chamber, locked in position, nor cooled at this stage. The focus of this step is solely on the removal of the used cartridge, which is essential for the proper cycling of the firearm's action.
