How to Use the Precision MOA Calculator:

This guide will walk you through using the MOA (Minute of Angle) calculator to determine the correct scope adjustments for your rifle based on bullet drop and distance.


Step 1: Enter Your Data

  1. Bullet Drop (inches)
  • Input the vertical distance your bullet drops (or rises) at a given range.
  • Example: If your bullet hits 12 inches low at 300 yards, enter 12.
  1. Distance (yards)
  • Enter the distance to your target in yards.
  • Default: 300 yards.
  1. Scope Click Value
  • Select your scope’s adjustment increment:
    • 1/4 MOA per click (Most common)
    • 1/2 MOA per click
    • 1 MOA per click

Step 2: Calculate MOA Adjustment

  • Click the “Calculate MOA” button (or let the tool auto-calculate as you type).
  • The results will display:
  • MOA: The total adjustment needed.
  • CLICKS: The number of clicks required on your scope turret.

Step 3: Apply the Adjustment

  • The tool will tell you:
  • Direction: Turn your turret UP or DOWN.
  • Clicks Needed: Example: “Turn your turret UP 16 clicks on a 1/4 MOA scope.”

Step 4: Visual Hold Reference

  • The reticle display shows where to hold if you prefer not to adjust your scope.
  • Example: “Hold 4 MOA high for 300 yards.”
  • The red dot indicates the holdover point.

Tips for Best Results

Double-check inputs – Ensure bullet drop and distance are accurate.
Verify scope settings – Confirm your scope’s click value (usually 1/4 MOA).
Field test – Confirm adjustments at the range.


Example Scenario

  • Bullet Drop: 12 inches
  • Distance: 300 yards
  • Scope Click Value: 1/4 MOA
  • Result:
  • 4.0 MOA adjustment
  • 16 clicks UP

This tool helps eliminate guesswork and ensures precise long-range shots. Happy shooting!

What is an MOA Calculator?

An MOA (Minute of Angle) calculator helps shooters adjust their rifle scopes for bullet drop at different distances. By inputting key data like bullet drop and range, it calculates the exact MOA correction and number of scope clicks needed for accurate long-range shots.

How Does It Work?

The calculator uses a simple formula:
MOA = (Bullet Drop in Inches) / (Distance in Yards / 100)
For example, if your bullet drops 12 inches at 300 yards, the MOA adjustment is 4.0 MOA. If your scope adjusts in ¼ MOA per click, you’d need 16 clicks (4 ÷ 0.25 = 16).

Where to Get Input Values for MOA Calculator?

  • Bullet Drop: Measure from ballistic tests, chronographs, or manufacturer data.
  • Distance: Use a laser rangefinder or known target range.
  • Scope Click Value: Check your scope’s manual (common: ¼, ½, or 1 MOA per click).

How to Calculate MOA Manually

  1. Convert distance to hundreds of yards (e.g., 300 yards = 3).
  2. Divide bullet drop by this number (e.g., 12″ ÷ 3 = 4 MOA).
  3. Divide MOA by your scope’s click value (e.g., 4 ÷ 0.25 = 16 clicks).

What if my scope uses MILs instead of MOA?

MOA and MILs are different units (1 MIL ≈ 3.6 MOA). Use a MIL calculator or convert (1 MOA ≈ 0.29 MILs).

Does MOA change with different calibers?

No, MOA is an angular measurement (1 MOA ≈ 1.047″ at 100 yards), but bullet drop varies by caliber.

How precise should my inputs be?

Measure bullet drop and distance as accurately as possible—small errors compound at long range.

Why does my calculated adjustment not match real-world results?

Wind, temperature, and barrel harmonics affect trajectory. Always verify with live fire.
