What’s an MOA Calculator?
If you’ve ever missed a long-range shot because your bullet dropped more than expected, you need an MOA Calculator. This tool takes the guesswork out of scope adjustments by telling you exactly how many clicks to turn your turrets for perfect accuracy.
Whether you’re a hunter, competitive shooter, or just getting into long-range precision, this guide will explain:
- What MOA is (and why it matters)
- How to use the calculator (step-by-step)
- Why it’s essential for first-shot hits
- Who benefits most from MOA adjustments
What is MOA? (Minute of Angle Explained)
MOA = Minute of Angle (1/60th of a degree).
- At 100 yards, 1 MOA ≈ 1 inch (technically 1.047″)
- At 500 yards, 1 MOA ≈ 5 inches
- Used for scope adjustments (elevation & windage)
MOA vs. MILs
| Feature | MOA | MILs |
|---|---|---|
| Measurement | 1″ @ 100yd | 3.6″ @ 100yd |
| Common Use | Hunters & US Shooters | Military & PRS Competitors |
| Precision | Finer adjustments | Faster calculations |
How to Use the MOA Calculator (Step-by-Step)
Inputs Needed:
- Bullet Drop (inches) – How low/high your shot hit vs. the aim point.
- Example: “12 inches low at 300 yards.”
- Distance (yards) – How far your target is.
- Scope Click Value – Usually 1/4, 1/2, or 1 MOA per click.
Results You Get:
- MOA Adjustment – Exact MOA correction needed.
- Click Count – How many scope clicks to turn.
- Visual Guide – Where to hold in your reticle.
Example Calculation:
- Drop: 15″ at 300 yards
- MOA: (15 ÷ 3) = 5 MOA
- Clicks (1/4 MOA scope): 5 × 4 = 20 clicks UP
Why This Calculator is Essential
✔ No More Guesswork – Stop “holding high” and missing.
✔ First-Shot Hits – Critical for hunting ethical kills.
✔ Saves Ammo – Fewer rounds wasted on zeroing.
✔ Works for Any Rifle – AR-15, .308, 6.5 Creedmoor, etc.
Who Should Use It?
Hunters
- Make ethical shots at 300+ yards.
- Adjust for uphill/downhill angles.
Long-Range Shooters
- Dial precise corrections in competitions.
- Compensate for wind drift.
Beginners
- Learn how bullet drop works.
- Understand scope adjustments.
How do you calculate MOA (Minute of Angle)?
Formula:
Example:
- Drop: 24″ at 600 yards
- MOA: 24 ÷ (600 ÷ 100) = 4 MOA
Why MOA Matters in Shooting
- At 1,000 yards, a .308 Win bullet drops 300+ inches.
- Without MOA adjustments, you’ll miss by feet, not inches.
- Even a 1 MOA error = 10″ miss at 1,000 yards!
FAQs
Q: Is 1 MOA exactly 1 inch at 100 yards?
Ans: Almost! It’s 1.047 inches, but most round to 1″ for simplicity.
Q: How many clicks is 1 MOA on my scope?
- 1/4 MOA scope: 4 clicks = 1 MOA
- 1/2 MOA scope: 2 clicks = 1 MOA
Q: Can I use MOA for windage?
Ans: Yes! 1 MOA wind hold ≈ 1″ drift per 100 yards (adjust for wind speed).
Q: Why is my real-world drop different from the calculator?
Ans: Possible causes:
- Ammo velocity variations
- Incorrect zero distance
- Extreme weather conditions
