How to Use Our Calculator

Select Your Caliber

Choose your caliber from the dropdown menu or select “Custom” to enter specific bullet parameters for any cartridge you use.

Enter Bullet Data

Input your bullet weight in grains and the ballistic coefficient (BC). Check your ammunition box or manufacturer’s website for this data.

Set Velocity & Zero

Enter your muzzle velocity in feet per second and specify your zero range in yards or meters based on your rifle setup.

Configure Scope Height

Measure and input the height of your scope’s centerline above the bore. This is typically between 1.5″ and 2.0″ for most setups.

Add Wind Conditions

Enter the current wind speed in mph and select the wind direction using the clock position system for accurate drift calculations.

Get Your Solution

Click “Calculate” to generate your complete ballistic table with drop, MOA/MIL adjustments, time of flight, and wind drift data.

Frequently Asked Questions

What is a Ballistic Coefficient (BC)?

The Ballistic Coefficient (BC) is a measure of a bullet’s ability to overcome air resistance in flight. A higher BC indicates the bullet retains velocity better and is less affected by wind. BC values are typically provided by bullet manufacturers and range from about 0.200 for short-range bullets to over 0.700 for long-range precision projectiles. G1 is the most common drag model used.

What’s the difference between MOA and MIL adjustments?

MOA (Minute of Angle) and MIL (Milliradian) are angular measurement systems used for scope adjustments. 1 MOA equals approximately 1.047 inches at 100 yards, while 1 MIL equals 3.6 inches at 100 yards. Most American hunting scopes use MOA, while tactical and military scopes often use MIL. Our calculator provides both so you can use whichever matches your optic.

How do I measure scope height above bore?

Scope height is measured from the center of the rifle bore to the center of the scope’s objective lens. For most standard mounts, this is typically 1.5″ to 1.6″. High mounts may be 1.75″ to 2.0″ or more. You can measure this directly with a ruler or caliper, or check your scope mount manufacturer’s specifications for precise measurements.

How does wind direction affect my shot?

Wind direction is expressed using clock positions. A 3 or 9 o’clock wind (directly from the side) has “full value” and causes maximum drift. Winds from 1, 2, 4, 5, 7, 8, 10, or 11 o’clock have “half value.” Winds from 12 or 6 o’clock (head-on or from behind) have minimal effect on horizontal drift but can slightly affect trajectory and velocity.

How accurate is this calculator?

Our calculator uses industry-standard ballistic formulas that provide excellent accuracy for most shooting scenarios. However, real-world results can vary due to factors like altitude, temperature, humidity, barrel length, and individual ammunition variations. We recommend using our calculations as a starting point and confirming with actual range time to fine-tune your data.

What Users Say

★★★★★

“This calculator has become an essential part of my long-range shooting toolkit. The accuracy is impressive, and I love that I can access it from my phone at the range. Made my first 800-yard shot thanks to this tool!”

Michael Harrison

Competition Shooter

★★★★★

“As a hunting guide, I’ve tried dozens of ballistic calculators. This one stands out for its simplicity and accuracy. My clients love how easy it is to use, and the results match what we see in the field consistently.”

Sarah Reynolds

Professional Hunting Guide

★★★★★

“Finally, a ballistic calculator that doesn’t require a subscription or downloading yet another app. I use this for both my .308 and 6.5 Creedmoor setups. The wind drift calculations are spot-on. Highly recommended!”
