The Hornady 147 ELD Match bullet in 6.5 Creedmoor is a favorite among long-range shooters for its exceptional accuracy and ballistic coefficient. This post provides a detailed look at its ballistics, exploring factors influencing its performance and offering insights for optimizing your shooting experience. We won't be providing a simple chart, as ballistic data is highly dependent on several variables; instead, we'll offer you the tools and knowledge to understand how to generate the most accurate chart for your specific setup.
Understanding the Variables Affecting Ballistics
Before diving into specifics, it's crucial to understand that a single, universal ballistics chart for the Hornady 147 ELD Match in 6.5 Creedmoor is impossible. Several factors significantly impact bullet trajectory and performance:
-
Muzzle Velocity: This is the speed of the bullet as it leaves the barrel. Variations in powder charge, barrel length, and even environmental conditions (temperature, humidity) will affect muzzle velocity. A higher muzzle velocity generally translates to a flatter trajectory and longer range.
-
Barrel Twist Rate: The rate of twist in your rifle barrel influences bullet stability. An incorrect twist rate can lead to poor accuracy and keyholing. Hornady provides recommendations for their bullets; ensure your barrel's twist rate is compatible.
-
Altitude and Air Density: Air density significantly impacts drag. Higher altitudes and lower air pressure result in less drag, leading to a flatter trajectory. Conversely, higher air density at lower altitudes or on humid days increases drag.
-
Temperature: Temperature affects both the propellant burn rate and the density of the air, impacting both muzzle velocity and drag. Cooler temperatures generally lead to slightly higher velocities.
-
Wind: Wind is arguably the most significant factor affecting long-range accuracy. Wind speed and direction must be carefully accounted for when making adjustments for long-range shots.
How to Generate Your Own Ballistics Chart
Rather than providing a potentially inaccurate generic chart, let's equip you with the resources to create your own personalized ballistics data. There are several excellent ballistic calculators and software programs available, both online and as dedicated applications. These tools typically require you to input the following:
-
Bullet Data: Weight (147 grains), ballistic coefficient (BC), and sectional density (SD). Hornady's website provides this information for their ELD Match bullets.
-
Muzzle Velocity: This needs to be determined through chronograph testing with your specific rifle and ammunition load.
-
Environmental Conditions: Altitude, temperature, pressure, and relative humidity must be factored in.
-
Sight Height: The distance between the bore axis and the center of your scope.
-
Zero Range: The distance at which your rifle is zeroed.
Popular ballistic calculators and software include:
-
Hornady 4DOF: Hornady's own ballistic calculator, readily available online.
-
Strelok Pro: A comprehensive and highly-rated ballistic app for smartphones and tablets.
-
Applied Ballistics Mobile: Another popular mobile app with advanced features.
-
JBM Ballistics: A comprehensive online ballistic calculator.
By using one of these tools and inputting your specific data, you'll generate a significantly more accurate and reliable ballistics chart for your rifle and ammunition setup.
Optimizing Your 6.5 Creedmoor 147 ELD Match Load
Remember that even with meticulously generated ballistics data, achieving optimal performance requires careful load development. Factors like powder type and quantity, primer type, and seating depth all impact accuracy and consistency. Work with a qualified gunsmith or experienced reloader to fine-tune your load for maximum precision.
