1. What is MOA?

MOA (Minute of Angle) is an angular measurement used in shooting to describe accuracy and precision. One MOA equals 1/60th of a degree, which is approximately 1 inch at 100 yards.

2. How Does the Calculator Work?

The calculator uses the MOA formula:

Where:

• \( Group\ Size \) — The size of the shot group in inches
• \( Distance \) — The distance to target in yards
• 100 — Conversion factor (100 yards)
• 60 — Conversion factor (60 minutes per degree)

Explanation: The equation converts the group size at a given distance to an angular measurement in minutes of angle.

3. Importance of MOA Calculation

Details: MOA is crucial for marksmen to understand rifle accuracy, make sight adjustments, and compare performance across different distances.

4. Using the Calculator

Tips: Enter group size in inches and distance in yards. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a good MOA value for a rifle?
A: For most hunting rifles, 1 MOA or less is considered excellent. Precision rifles often achieve sub-MOA accuracy.

Q2: How does MOA relate to MIL?
A: 1 MIL equals approximately 3.6 MOA. Both are angular measurements but use different base units (1/6400 of a circle vs 1/60 of a degree).

Q3: Why is MOA useful at different distances?
A: MOA provides a consistent angular measurement regardless of distance, making it easier to adjust sights for different ranges.

Q4: How does MOA affect bullet drop?
A: MOA helps calculate how much to adjust sights to compensate for bullet drop at various distances.

Q5: Can MOA be used for windage adjustments?
A: Yes, MOA adjustments work the same for both elevation (bullet drop) and windage (horizontal drift).
