The Burris Ballistic Calculator is a specialized tool designed to assist shooters in making precise long-range shots. It helps you calculate crucial information such as the velocity of your bullet at a specific range and the energy it retains at that distance. These calculations are vital for determining the trajectory and performance of your ammunition, allowing you to make more accurate shots.
Formula of Burris Ballistic Calculator
Velocity at Range
The velocity at a given range is calculated using the following formula:
velocityAtRange = initialVelocity - (range * 0.1)
- Initial Velocity: This is the speed at which the bullet leaves the firearm, measured in feet per second (ft/s).
Energy at Range
The energy at a specific range is determined using the formula for kinetic energy:
energyAtRange = 0.5 * (bulletWeight / 7000) * Math.pow(velocityAtRange, 2)
Now, let’s break down the components of this formula:
- Bullet Weight: This refers to the weight of the bullet in grains (gr). The Burris Ballistic Calculator allows you to input this value for precise calculations.
- Velocity at Range: We calculated this in the previous step, and it represents the bullet’s speed at the chosen range.
These formulas provide valuable insights into your ammunition’s performance at different distances, helping you adjust your aim and make more accurate shots.
General Terms Table
To make the most of your Burris Ballistic Calculator, it’s essential to understand some general terms frequently used in long-range shooting. Here’s a handy table of terms that can assist you in using the calculator more effectively:
| Term | Description |
|---|---|
| Ballistic Coefficient | A measure of a bullet’s ability to overcome air resistance. Higher values indicate better aerodynamic performance. |
| MOA (Minute of Angle) | A unit of angular measurement often used to express accuracy and adjust rifle scopes. |
| Wind Drift | The effect of wind on the trajectory of a bullet. |
| Bullet Drop | The vertical distance a bullet falls below the line of sight at a specific range. |
| Twist Rate | The rate of rifling twist in the barrel, affecting bullet stability and accuracy. |
| Zeroing | The process of adjusting a scope to align with the point of impact at a specific distance. |
Understanding these terms will enhance your ability to interpret the results provided by the Calculator and make more informed decisions while shooting.
Example of Burris Ballistic Calculator
Let’s illustrate how the Calculator works with an example:
Suppose you have a rifle with an initial velocity of 3000 ft/s, a bullet weight of 150 grains, and you’re shooting at a range of 500 yards. Using the calculator, you can determine the velocity at 500 yards and the energy retained by the bullet at that distance.
- Velocity at Range:
velocityAtRange = 3000 - (500 * 0.1) = 2500 ft/s - Energy at Range:
energyAtRange = 0.5 * (150 / 7000) * (2500^2) = 2607.14 ft·lbf
These calculations provide valuable data that can help you adjust your shot placement accurately, taking into account the bullet’s velocity and energy at the specified range.
