Question: 1 / 400

What is the primary cause of a failure to extract a spent casing from a chamber?

A weak powder charge

The primary cause of a failure to extract a spent casing from a chamber can be linked to issues with the ammunition being used, specifically a weak powder charge. When a round is fired, the pressure created by the combustion of the powder is what propels the bullet and also helps to force the casing backwards against the extractor. If the powder charge is insufficient, the pressure may not be enough to fully cycle the action of the firearm, which can lead to the spent casing not being properly ejected from the chamber.

In contrast, having a clean chamber typically facilitates the extraction process, as it allows for smoother operation of the casing during cycling. A properly functioning extractor is essential for the removal of the casing, and an intact rim on the case ensures the extractor can grip it effectively. Therefore, while a weak powder charge directly impacts the force applied during extraction, the other factors mentioned would support the proper functioning of the firearm's cycling mechanism.
