Which malfunction occurs when the bullet does not exit the barrel?

A bullet that does not exit the barrel indicates a significant issue during the firing sequence, which is indicative of a squib load. A squib load occurs when a bullet is improperly loaded, resulting in insufficient propellant charge. This can lead to the situation where the bullet does not have enough force to exit the barrel after being fired.

Recognizing a squib load is crucial because if the shooter continues to fire subsequent rounds without addressing the underlying issue, it can lead to catastrophic failure, including potential barrel obstruction. Immediate attention is required to ensure the firearm is safe and operational.

Understanding this type of malfunction is essential for safe shooting practices, particularly in recognizing and resolving issues related to ammunition and its performance.
