What is the primary distinction between a push feed and a control feed bolt action rifle?

The primary distinction between a push feed and a control feed bolt action rifle lies in the way the cartridge is fed into the chamber. In a control feed system, the extractor is designed to engage the cartridge rim as it is being fed into the chamber, ensuring that the cartridge is held securely during feeding. This mechanism allows for reliable extraction after firing, even in adverse conditions.

In contrast, a push feed system relies on the bolt pushing the cartridge forward into the chamber without the extractor engaging the cartridge until it is fully chambered. This can lead to situations where a cartridge may not be entirely controlled by the extractor during the feeding process, making it slightly less reliable in certain situations, such as when the rifle is tilted or if there are issues with the magazine.

Thus, the correct answer highlights the specific function of the extractor in relation to the feeding process, which is the key differentiator between these two types of bolt action rifles.
