Interactive Burris Ballistic Calculator
Enter your load and setup data to generate a quick trajectory and wind chart. This is a simplified field calculator for planning and practice.
For educational use only. Always confirm with real-world range data and your optics/manual before making adjustments.
How this burris ballistic calculator helps
A ballistic calculator gives you a faster way to estimate bullet behavior at distance. Instead of guessing holdover, you can build a practical starting chart for drops and wind drift, then true it at the range. If you use Burris optics, this kind of pre-built data helps speed up turret adjustments and reticle hold decisions.
This page is designed in a clean, blog-style GeneratePress layout so it feels familiar and easy to use. The calculator is intentionally straightforward: enter core values, click calculate, and review a table you can screenshot or copy into your range notebook.
What each input means
Muzzle velocity (fps)
Your measured speed at the muzzle. Chronograph data is best. Factory box velocity is useful for initial setup but usually optimistic compared to your actual barrel.
Bullet weight (grains)
Used to estimate energy values along the trajectory. Heavier bullets can carry energy differently, but drag profile still matters a lot.
Ballistic coefficient (G1)
BC models how efficiently a bullet flies through air. A higher BC generally means less deceleration and less wind impact over distance.
Sight height and zero range
Sight height is the distance between your optic centerline and bore centerline. Zero range defines where your line of sight and bullet trajectory intersect. Together, these values shape the path curve shown in the table.
Crosswind speed
Wind drift is shown as a practical estimate for a full-value crosswind. Real wind changes by terrain, direction, and distance, so use this as a baseline.
Reading the output table
- Path (in): Bullet location relative to your line of sight at each distance.
- Hold (MOA / MIL): Suggested angular correction needed when impact is below aimpoint.
- Velocity: Remaining speed estimate at each range mark.
- Energy: A quick impact energy reference in foot-pounds.
- Wind Drift: Estimated horizontal movement from a full-value crosswind.
Best practices for more accurate results
1) Start with real chronograph data
Use at least a 5-shot average (10 is better). Small velocity errors can create noticeable misses as range increases.
2) Confirm your true zero
If your zero is off by even a little, your entire chart shifts. Reconfirm zero before building dope cards.
3) Match your units and turret system
If your scope tracks in MOA, keep a MOA workflow. If your reticle/turrets are MIL-based, use MIL values consistently.
4) Validate in the environment you shoot in
Temperature, altitude, and density can change trajectory. A chart built at sea level may not match mountain conditions.
Frequently asked questions
Is this identical to a manufacturer ballistic engine?
No. This is a simplified calculator intended for planning and learning. Manufacturer apps may include more advanced drag modeling and environmental factors.
Why do my real impacts still differ?
Typical causes include true BC variation, inaccurate velocity assumptions, wind uncertainty, and minor zero offsets.
Can I print this chart?
Yes. After calculation, you can print the page or save a screenshot of the result table for field reference.
Final thoughts
A burris ballistic calculator is most useful when it supports a repeatable process: gather good input data, generate a clean chart, test at distance, and refine. Use this page as a practical starting point for your trajectory notes, then tune it with confirmed range performance.
