Calculate Minute of Angle (MOA)

How to Calculate MOA

Understanding MOA

MOA, or Minute Of Angle, is an angular measurement used in shooting to describe accuracy and adjust sighting. One MOA is approximately equal to (2) x (3.1416) x (R) / (21,600), where R is the distance to the target in yards. Commonly, one MOA is approximated as one inch per 100 yards, increasing proportionally with the distance.

Calculating MOA for Adjustments

To calculate MOA, start by dividing the shooting distance (in yards) by 100. This division gives the size of one MOA in inches at that distance. For instance, at 300 yards, 1 MOA equals approximately 3 inches. If adjustments are necessary, you determine how many MOA increments relate to your needed correction by dividing the intended adjustment in inches by the size of 1 MOA at the specific distance. For example, to adjust 18 inches at 600 yards, calculate 18 / 6 = 3 MOA.

Tools and Resources for MOA Calculation

Essential tools for calculating MOA include the MOA Reticle Formula Calculator and the Measuring MOA Reticle Formula Calculator. Accurate calculations can also utilize resources like the MIL Dot Formula to enhance sighting adjustments.

Practical Example of MOA Calculation

A practical understanding can be seen in making adjustments based on shooting results. For example, if your shots at 800 yards land 16 inches to the left, you would correct this by making a 2 MOA adjustment to the right. This adjusts the point of impact closer to the target center, refining accuracy.

Calculating MOA accurately optimizes shooting performance, essential for both recreational and competitive shooting.

How to Calculate MOA (Minute of Angle)

Understanding MOA Calculation

MOA, or Minute of Angle, is an angular measurement that spreads to 1" per 100 yards. As distance increases, 1 MOA increases linearly, reaching 12" at 1200 yards. This makes MOA a crucial concept for precision shooting, where accuracy over varying distances is paramount.

Calculating Inches per MOA

To determine how wide 1 MOA is at your target distance, use the formula: (Distance to target in yards) / 100 = inches per MOA at that distance. For instance, at 300 yards, 1 MOA is 3 inches.

Calculating Needed MOA Adjustment

Once you know how wide 1 MOA is for your distance, calculate the required adjustment in MOA if your shots are off target. Use the formula: (Number of inches of adjustment needed) / (inches per MOA at that distance) = MOA adjustment. For a 15-inch correction at 300 yards, where 1 MOA is 3 inches, you’ll need a 5 MOA adjustment.

Adjusting the Rifle Scope

Translate your MOA adjustment to scope clicks, often necessary for fine-tuning shot accuracy. You’ll need to know how many clicks per 1 MOA your scope provides, commonly 1/4 MOA per click. Thus, compute the total clicks required using: (Number of clicks per 1 MOA on scope) x (MOA adjustment) = adjustment in clicks on scope. For a 5 MOA adjustment with a 1/4 MOA per click scope, adjust 20 clicks.

Final Touches and Corrections

After making these adjustments, it’s essential to test fire and reassess, since variables like windage and shooter positioning can affect precision. Always think in MOA increments during adjustments to maintain consistency and precision over varying distances.

Calculating MOA: Practical Examples

Example 1: Zeroing a Rifle at 100 Yards

To zero a rifle at 100 yards, consider that 1 MOA is approximately 1 inch at 100 yards. If your bullet impact is 4 inches off target, adjust the scope by 4 MOA.

Example 2: Long-Distance Shooting Correction

For a target 500 yards away, 1 MOA equals approximately 5 inches. If your shot hits 10 inches low, adjust your scope up by 2 MOA to compensate.

Example 3: Using MOA for Scope Mounting

When mounting a scope, ensure that the reticle adjustments match the expected MOA per click, commonly 1/4 MOA. This precision ensures accuracy in adjustments.

Example 4: Benchmarking Rifle Accuracy

A rifle's accuracy can be tested by shooting groups. A group that measures 1 inch at 100 yards demonstrates a 1 MOA accuracy, indicating high precision.

Example 5: Hunting Adjustments

In hunting, quick MOA calculations can aid in swift scope adjustments. Facing a 300-yard shot, a 3-inch correction requires a 1 MOA adjustment on the scope.
