Ballistics Calculator App Formula
t ≈ Distance / (Avg. Velocity)
V_final = V_initial * exp(-k * Distance)
Reference: Hornady External Ballistics Resources
Variables Explained:
- Muzzle Velocity: The speed of the bullet as it leaves the barrel, measured in feet per second (fps).
- Ballistic Coefficient (BC): A measure of a bullet’s ability to overcome air resistance in flight. We use the G1 standard.
- Bullet Weight: Measured in grains, affecting momentum and energy retention.
- Zero Range: The distance at which your sights are perfectly aligned with the bullet path.
- Target Distance: The actual distance to your intended target.
What is Ballistics Calculator App?
A ballistics calculator app is a specialized tool used by shooters to predict the flight path of a projectile. By accounting for gravity, air resistance (drag), and initial velocity, the app provides precise adjustments for optics, often expressed in Inches, MOA (Minutes of Angle), or MRAD (Milliradians).
Modern external ballistics models, such as the Siacci method or point-mass models, allow for high-accuracy predictions even at distances exceeding 1,000 yards. This technology is essential for long-range hunting and tactical shooting where “first-shot hits” are critical.
How to Calculate Ballistics (Example)
- Enter your Muzzle Velocity (e.g., 2800 fps).
- Input your bullet’s G1 Ballistic Coefficient (e.g., 0.510).
- Define your Zero Range (usually 100 yards).
- Select the Target Distance (e.g., 400 yards).
- Press Calculate to see the hold-over adjustment.

Frequently Asked Questions (FAQ)
What is the G1 vs G7 Ballistic Coefficient? G1 is for flat-base bullets, while G7 is more accurate for modern boat-tail long-range bullets.
Does temperature affect bullet drop? Yes, colder air is denser and increases drag, causing the bullet to drop more quickly.
Why is my zero range important? Your zero range defines the baseline for all trajectory adjustments. Most hunters prefer a 100-yard zero.
Is windage included in this calculation? This simplified app focuses on vertical drop; windage requires lateral wind speed inputs.
