The 6.5 Creedmoor cartridge has rapidly gained popularity among long-range shooters, and the Hornady 147 ELD Match bullet is a significant reason why. This bullet's exceptional ballistic coefficient (BC) contributes to its renowned accuracy and downrange performance. This article delves into the Hornady 6.5 Creedmoor 147 ELD Match ballistics, providing a comprehensive understanding of its capabilities, limitations, and practical applications. We'll explore various aspects, including muzzle velocity, trajectory, energy retention, and effective range, utilizing data from Hornady's published information and other reliable sources.
Understanding Ballistics: What Affects Bullet Flight?
Before diving into the specifics of the 147 ELD Match, let's briefly cover the key factors influencing bullet ballistics:
-
Ballistic Coefficient (BC): This is a crucial measure of a bullet's ability to overcome air resistance. A higher BC means less drag, resulting in a flatter trajectory and less wind drift at longer ranges. The 147 ELD Match boasts a high BC, a key factor in its success.
-
Muzzle Velocity: This is the speed at which the bullet leaves the barrel. Higher muzzle velocity generally translates to a flatter trajectory and longer range, but it also increases recoil.
-
Twist Rate: The rate of rifling twist in the barrel affects bullet stability. An improper twist rate can lead to keyholing (the bullet tumbling in flight). The 6.5 Creedmoor typically uses a 1:8" or 1:7.7" twist rate, which is well-suited for the 147 ELD Match.
-
Altitude and Temperature: These environmental factors significantly impact bullet performance. Higher altitudes and lower temperatures result in thinner air, reducing drag and potentially increasing range.
Hornady 147 ELD Match Ballistics Data: A Sample Chart
While precise ballistic data varies slightly depending on factors like barrel length, twist rate, and atmospheric conditions, Hornady provides estimations for their ammunition. A typical ballistic chart (this is a sample, and you should consult Hornady's official data for your specific load) might look like this:
| Distance (Yards) | Velocity (fps) | Energy (ft-lbs) | Drop (inches) | Wind Drift (10 mph crosswind, inches) |
|---|---|---|---|---|
| 100 | 2750 | 2200 | 1.0 | 2.0 |
| 200 | 2550 | 1900 | 4.5 | 7.0 |
| 300 | 2400 | 1600 | 10.0 | 14.0 |
| 400 | 2250 | 1350 | 17.5 | 23.0 |
| 500 | 2100 | 1150 | 27.0 | 34.0 |
| 600 | 1950 | 950 | 38.5 | 47.0 |
| 700 | 1800 | 780 | 52.0 | 62.0 |
| 800 | 1650 | 630 | 67.5 | 79.0 |
| 900 | 1500 | 500 | 85.0 | 98.0 |
| 1000 | 1350 | 390 | 105.0 | 119.0 |
Note: This is a representative chart and may not reflect the exact performance of your specific setup. Always consult the manufacturer's data and conduct your own testing for precise results.
Factors Affecting Real-World Performance
The chart above provides a theoretical estimate. Real-world performance can be affected by:
- Barrel Length: Longer barrels generally yield higher muzzle velocities.
- Powder Charge: Slight variations in powder charge can significantly impact velocity and accuracy.
- Altitude and Temperature: As mentioned earlier, these factors influence air density, directly impacting bullet trajectory.
- Wind: Wind is a major factor at longer ranges. Crosswinds will cause significant drift, while headwinds and tailwinds will affect range.
Case Study: A Long-Range Shooting Example
Imagine a scenario where you're shooting at a target 600 yards away. The sample chart above shows approximately 38.5 inches of drop and 47 inches of wind drift (with a 10mph crosswind). To accurately hit the target, you would need to compensate for both drop and wind drift through scope adjustments and proper shooting techniques. This highlights the importance of understanding your ammunition's ballistics.
Conclusion: Mastering the Hornady 147 ELD Match
The Hornady 6.5 Creedmoor 147 ELD Match bullet is a high-performing option for long-range shooting. Understanding its ballistics characteristics is crucial for achieving accuracy and consistent results. By consulting reliable data sources, conducting thorough testing, and mastering proper shooting techniques, you can maximize the potential of this exceptional bullet. Remember to always prioritize safety and consult manufacturer's guidelines. Don't rely solely on theoretical charts; real-world conditions will always influence your results.
