Is there a difference in effectiveness between hollow-point and FMJ?

Choosing the Right Ammunition for Defense

When it comes to prepper defense sidearms, the type of ammunition used can significantly impact its effectiveness. Hollow-point ammunition, also known as expanded ammunition, is designed to expand upon impact, creating a larger wound channel. This can be beneficial in self-defense situations where the goal is to stop the threat as quickly and efficiently as possible. The expansion also helps to increase the surface area of the wound, making it more difficult for the threat to continue to fight.

Comparison of Hollow-Point and FMJ Ammunition

In contrast, FMJ ammunition, also known as full-metal jacket ammunition, is designed to penetrate more deeply and maintain its shape upon impact. While this can be beneficial in certain situations, such as hunting, it may not be the best choice for prepper defense sidearms. FMJ ammunition can over-penetate, potentially causing damage to bystanders or valuable equipment. In a self-defense scenario, the last thing you want is to cause collateral damage.

Real-World Considerations

In a real-world scenario, the effectiveness of hollow-point ammunition can be seen in its ability to stop threats quickly. For example, a 9mm hollow-point round may expand to 0.6-0.7 inches in diameter, creating a larger wound channel and increasing the chances of stopping the threat. In contrast, a 9mm FMJ round may only penetrate 12-18 inches before coming to a stop, increasing the risk of over-penetration and collateral damage. When it comes to prepper defense sidearms, the choice of ammunition should be based on the specific needs of the situation.
