The Hornady 62 grain FMJ (Full Metal Jacket) bullet is a popular choice among shooters, finding applications in various disciplines from target practice to self-defense. This comprehensive guide delves into the specifics of this projectile, exploring its ballistics, performance characteristics, and suitability for different uses.
Understanding the Hornady 62 Grain FMJ
Hornady, a renowned ammunition manufacturer, produces the 62 grain FMJ in various calibers, most notably the ubiquitous 5.56x45mm NATO and .223 Remington. The 62-grain weight offers a balance between velocity and stability, making it a versatile round. The full metal jacket construction ensures consistent performance and minimizes leading in the barrel, contributing to longer barrel life.
Key Features and Specifications:
- Full Metal Jacket (FMJ): This design completely encases the lead core with a harder metal jacket, typically copper-plated. This offers better accuracy and less fouling than lead bullets.
- 62 Grain Weight: This weight provides a good balance between velocity and downrange energy for various applications.
- Caliber Variations: Available in multiple calibers, the 5.56x45mm NATO/.223 Remington variants are particularly well-known.
- Consistent Performance: The FMJ design generally delivers predictable ballistic performance, minimizing variations in accuracy and trajectory.
Ballistic Performance and Trajectory
The ballistic performance of the Hornady 62 grain FMJ varies slightly depending on the specific cartridge and barrel length. However, generally, you can expect:
- Moderate Recoil: The 62-grain weight minimizes felt recoil, making it comfortable for extended shooting sessions.
- Flat Trajectory: The bullet's weight and design contribute to a relatively flat trajectory, simplifying target acquisition at moderate ranges.
- Good Accuracy: With proper ammunition and firearm maintenance, the 62 grain FMJ delivers acceptable accuracy for target shooting and plinking.
Factors Affecting Performance:
- Barrel Length: Longer barrels generally yield higher velocities and flatter trajectories.
- Twist Rate: The rifle's twist rate affects bullet stability, impacting accuracy and downrange performance.
- Powder Charge: Variations in powder charge can influence velocity and overall ballistics.
Applications of the Hornady 62 Grain FMJ
The Hornady 62 grain FMJ proves its versatility across a range of shooting disciplines:
1. Target Practice and Plinking:
This round is an excellent choice for target practice due to its affordability and consistent performance. The moderate recoil makes it suitable for both novice and experienced shooters.
2. Competition Shooting:
In certain shooting competitions where FMJ ammunition is allowed, the 62-grain projectile’s accuracy and reliability make it a competitive choice.
3. Self-Defense (Considerations):
While the Hornady 62 grain FMJ is suitable for target practice and some competition shooting, it's crucial to acknowledge that its full metal jacket design might not expand upon impact. This limits its effectiveness in self-defense scenarios where maximum stopping power is paramount. For self-defense, consider expanding ammunition options specifically designed for that purpose.
Conclusion: A Versatile and Reliable Round
The Hornady 62 grain FMJ is a dependable and versatile round suitable for various applications. Its accuracy, consistent performance, and moderate recoil make it a popular choice for target practice and certain types of competition shooting. However, it's crucial to choose the correct ammunition for its intended purpose, understanding the limitations of FMJ projectiles in self-defense situations. Always prioritize safety and responsible firearm handling.
