Calculating MOA – The Details You Have to Know

Do you often hear people say that sub-MOA rifle is their choice? You have already heard people say a few comments about this. Unless you know what MOA is, then you may not be able to relate. You can learn more about what MOA is and how it is calculated. Trust us, the more that you understand, the more that you will be able to relate to other people’s enthusiasm about it.

Knowing What MOA is

MOA stands for Minute of Angle. This is the angular value of 1/60th of a degree. Let us say that you would like to describe how the target is hit depending on the distance. You will be able to do that with the use of MOA. The scopes of the adjustments will usually be stated in MOA.

For example, you have done one click of your scope. This is going to be equal to ¼ MOA. If you shoot at 500 yards and the bullet is off by 20 inches, you can already compute. You already have all of the needed details.

To calculate the correction, you are going to follow this formula: 20 inches/5 (hundreds of yards) =4 MOA. You need to do 16 clicks on your scope to make this effective.

The more that you understand how to compute for MOA, the more that you will understand how your rifle behaves. This can be effective because you can base the things that you will do on the wind and the distance from where you are going to shoot. You can also make adjustments to your scope to use it properly.

Will Magnification Affect MOA?

Remember that each scope will have limited number of windage. You may purchase a scope with a magnification that will be ineffective for whatever you have in mind. The excess correction margin should always coincide with the ammunition that you are going to fire. This is even going to be more important if you would usually fire from long ranges.

Different things can become affected because of magnification such as the following:

  • The size of your target
  • The distance from where you are to your target
  • Accuracy of the shot

There is a solution to make things better. Mil-Dot crosshairs have been introduced. Those who understand how to use this will be able to use this to their advantage. Those who do not know how to read the angular minute may have a bit of trouble using this.

The best thing about this is that it can eliminate the need for some verticals. You just have to know the distance to the target or the height from where you are shooting your target multiplied by 1000 and divide that to the number of dots in the Mil-Dot.

The reticle may be affected depending on the scope that you have. Others can be used wherein the magnification will be unchanged no matter if you would be changing the magnification of the product.

You cannot consider the click value because this does not have any dependency on the magnification that you are using. The click price is going to be the same for all types of magnification. What will be different is the click value. This will change depending on the distance.


The more that you can use your scope to your advantage, the better your target accuracy is going to be. You need this. Just imagine if you would have all the best items but you cannot even hit your target. Knowing how to compute for MOA will make a lot of difference.
