FMJ Vs Hollow Point Comparison: Understanding the Key Differences
The jacket prevents the bullet from deforming upon impact, which allows it to maintain its velocity and trajectory over distance. Proper storage, handling, and ensuring the correct caliber for your firearm are non-negotiable practices for any responsible shooter.
This design also reduces barrel fouling compared with lead-only bullets, making it a practical choice for military training and combat where reliability is paramount. Law enforcement and military units often utilize modified FMJ variants, such as jacketed hollow points, for duty weapons, but standard FMJ remains the staple for high-volume training sessions due to its low cost and dependable performance.
