What is a 'squib load'?

A 'squib load' refers to an insufficiently charged cartridge that fails to build adequate pressure for the projectile to exit the barrel. This situation can lead to dangerous consequences, as the bullet may become lodged inside the barrel, posing a significant risk of a catastrophic failure if another round is fired behind it. Recognizing a squib load is crucial for safety because it requires immediate action to clear the obstruction before continuing to use the firearm. Understanding this term is essential for firearm safety and malfunction diagnosis, helping shooters manage and respond to potential issues effectively.
