The MRAD Scope Calculator is a tool used to estimate the distance to a target based on the size of the target and the measurement in milliradians (MRAD) observed through the scope. By providing these two inputs, the calculator helps shooters make precise adjustments to their aiming point, enhancing accuracy.
Formula of MRAD Scope Calculator
To calculate the distance to a target using MRAD, you can use the following formula:
Components of the Formula
- Distance (meters): This is the estimated distance to the target.
- Target Size (meters): This is the actual size of the target, measured in meters.
- MRAD: This is the measurement in milliradians, which you can read from the scope.
Table of General Terms
Below is a table with pre-calculated distances for common target sizes and MRAD values:
| Target Size (meters) | MRAD | Distance (meters) |
|---|---|---|
| 0.5 | 1 | 500 |
| 0.5 | 2 | 250 |
| 1 | 1 | 1000 |
| 1 | 2 | 500 |
| 1.5 | 1 | 1500 |
| 1.5 | 2 | 750 |
Example of MRAD Scope Calculator
Let’s go through an example to illustrate how the MRAD Scope Calculator works:
- Measure the actual size of the target. Let’s say the target is 1.2 meters tall.
- Look through your scope and note the MRAD reading. Suppose it reads 3 MRAD.
- Apply the formula:Distance (meters) = (1.2 meters * 1000) / 3 MRAD = 1200 / 3 = 400 meters
Therefore, the estimated distance to the target is 400 meters.
Most Common FAQs
MRAD Scope Calculators are generally accurate when the inputs (target size and MRAD reading) are precise. The accuracy depends on the shooter’s ability to measure the target size accurately and read the scope correctly
Yes, the MRAD formula can be use with any scope that provides MRAD measurements. However, ensure that your scope is properly calibrate and that you are familiar with its specific MRAD readings.
MRAD (milliradian) and MOA (minute of angle) are both angular measurements used in shooting. MRAD is part of the metric system, while MOA is part of the imperial system. 1 MRAD is approximately 3.44 MOA. Shooters choose between MRAD and MOA based on personal preference and the system they are more comfortable with.
