Is FMJ Good For Self-Defense?

Full metal jacket (FMJ) bullets are a type of ammunition that is commonly used in military and law enforcement applications. They are designed to penetrate through hard targets, such as body armor or metal barriers, and to minimize the risk of ricochet. However, there is some debate as to whether or not FMJ bullets are a good choice for self-defense.

Advantages of FMJ Bullets

  • Penetration: FMJ bullets are designed to penetrate through hard targets, making them effective against body armor or other hard barriers.
  • Accuracy: FMJ bullets are typically more accurate than other types of ammunition, making them easier to hit a target at long range.
  • Reliability: FMJ bullets are very reliable and are less likely to jam or malfunction in a firearm.

Disadvantages of FMJ Bullets

  • Overpenetration: FMJ bullets can overpenetrate a target, meaning that they can continue to travel after they have hit their intended target and potentially injure or kill innocent bystanders.
  • Ricochet: FMJ bullets can ricochet off of hard surfaces, such as concrete or metal, and potentially strike unintended targets.
  • Lack of Stopping Power: FMJ bullets do not expand when they hit a target, which means that they can cause less damage than other types of ammunition.


Whether or not FMJ bullets are a good choice for self-defense is a matter of debate. There are both advantages and disadvantages to using FMJ bullets for self-defense, and the best choice for an individual will depend on their specific needs and circumstances.

If you are considering using FMJ bullets for self-defense, it is important to carefully weigh the advantages and disadvantages of this type of ammunition and to make sure that you are aware of the potential risks involved. You should also consult with a qualified firearms instructor to get training on how to use FMJ bullets safely and effectively.
