FMJ or Hollow Points?

Duration: 1:04

This video explains the fundamental differences between Full Metal Jacket (FMJ) and Hollow Point (HP) ammunition. FMJs, with their lead core encased in metal, are ideal for range practice due to reliability and cost-effectiveness. Hollow points are designed for self-defense, expanding on impact to increase stopping power and reduce over-penetration, with some variations featuring fillers to prevent premature expansion.

Quick Summary

FMJ (Full Metal Jacket) ammunition features a lead core fully encased in metal, designed for reliable feeding and cost-effectiveness, making it ideal for range practice. Hollow point ammunition has a cavity at the tip that causes it to expand on impact, increasing stopping power and reducing over-penetration, which is crucial for self-defense applications.

Frequently Asked Questions

What is the primary difference between FMJ and Hollow Point ammunition?

FMJ (Full Metal Jacket) ammo has a lead core fully encased in metal, designed for reliable feeding and range use. Hollow points have a cavity at the tip that causes them to expand on impact, increasing stopping power and reducing over-penetration, making them ideal for self-defense.

Why is FMJ ammunition recommended for range practice?

FMJ rounds are generally less expensive and widely available, making them a cost-effective choice for frequent shooting. Their full metal jacket construction also ensures smooth and reliable feeding in most firearms, minimizing malfunctions during practice sessions.

How do hollow point bullets improve self-defense effectiveness?

The cavity in a hollow point bullet is designed to expand upon hitting a target. This expansion increases the bullet's diameter, creating a larger wound channel for enhanced stopping power and also helps to prevent the bullet from passing completely through the target (over-penetration).

Are there variations of hollow point ammunition?

Yes, some hollow point bullets feature fillers, like colored rubber, in the tip cavity. This is to prevent premature expansion when the bullet encounters materials like thick clothing, ensuring it expands effectively only upon impact with the intended target.
