What is one potential consequence of firing more than 250 rounds without interruption?

Firing more than 250 rounds without interruption can lead to a potential cook-off, which is a hazardous situation. A cook-off occurs when the heat generated in the chamber of a firearm becomes sufficient to ignite the propellant in a round that is still in the chamber, even without the trigger being pulled. This can happen after sustained firing that causes the barrel and chamber to reach very high temperatures.

When a firearm is fired continuously, particularly in rapid succession, the components can experience significant heat buildup. This excessive heat can compromise the safety mechanisms and functioning of the weapon, leading to a loss of control over when rounds may be discharged. Understanding this risk emphasizes the necessity for periodic breaks during firing to allow for the cooling of the weapon, maintaining both the effectiveness and safety of the shooting.

In contrast, while firing more rounds might imply greater experience or familiarity with the weapon, it does not inherently lead to a cleaner firing capacity or improved shooting precision. Enhanced weapon reliability requires proper maintenance and cooling procedures, not just prolonged firing.
