There are four main causes of hunting incidents. Which cause includes having an obstructed barrel or improper ammunition?

• A. ignoring firearm safety rules
• B. lack of control and practice
• C. judgment mistakes
• D. mechanical failure

Answer: (D)

Mechanical failure covers problems inside the firearm or with the ammunition itself. An obstructed barrel, blocked by mud, snow, or debris, creates abnormal pressure when the gun is fired and can lead to a dangerous discharge. Improper ammunition can misfire, fail to fire, or cause unpredictable pressure, all of which are failures of the firearm/ammunition system rather than a shooter’s behavior. The other options describe unsafe actions or poor judgment, not a malfunction of the gun or ammo. So the scenario of an obstructed barrel or improper ammunition fits mechanical failure.
