1. What is MOA Adjustment?

MOA (Minute of Angle) adjustment is a method used to calculate the number of clicks needed on a rifle scope to correct for bullet impact deviation at a specific distance. It's essential for precision shooting and long-range accuracy.

2. How Does the Calculator Work?

The calculator uses the MOA adjustment formula:

\[ Adj = \frac{D}{100} \times \frac{1}{MOA} \]

Where:

Explanation: The formula calculates how many scope clicks are needed to adjust for a specific deviation at 100 yards. Each click moves the point of impact by a specific MOA value.

3. Importance of MOA Calculation

Details: Accurate MOA calculation is crucial for precision shooting, competition shooting, hunting, and military/law enforcement applications where shot placement is critical.

4. Using the Calculator

Tips: Enter the deviation in inches and your scope's MOA per click value. Most scopes have 1/4 MOA, 1/2 MOA, or 1 MOA per click adjustments.

5. Frequently Asked Questions (FAQ)

Q1: What is MOA exactly?
A: MOA (Minute of Angle) is an angular measurement equal to 1/60th of a degree, approximately 1 inch at 100 yards.

Q2: How does distance affect MOA adjustments?
A: MOA adjustments are angular, so the same click adjustment will move the point of impact more at longer distances. This calculator assumes 100 yards.

Q3: What are common MOA values for scopes?
A: Most quality scopes offer 1/4 MOA per click, but some may have 1/2 MOA, 1/8 MOA, or 1 MOA per click adjustments.

Q4: Can I use this for mil-dot scopes?
A: This calculator is specifically for MOA adjustments. Mil-dot scopes use a different measurement system (1 mil = 3.6 inches at 100 yards).

Q5: How accurate is this calculation?
A: The calculation is mathematically precise, but real-world results may vary due to environmental factors, ammunition consistency, and shooter technique.
