What is a squib load?

A squib load refers to a situation where the primer of a cartridge ignites, but the powder charge either fails to ignite completely or there is not enough powder to propel the bullet with sufficient force. As a result, the bullet does not exit the barrel and becomes lodged somewhere within it. This is a dangerous condition because if another round is fired afterward, it can create a dangerous obstruction that leads to a catastrophic failure of the firearm.

Recognizing a squib load is critical for maintaining safety during shooting practices, as it requires immediate action to clear the firearm before firing again. Understanding these characteristics helps shooters remain vigilant and responsive to potential issues that may arise during training or while handling firearms.
