When it comes to shooting and long-range accuracy, two of the most commonly used measurements are MOA (Minute of Angle) and MRAD (Milliradian). These terms can be confusing for novice shooters, but they are crucial to understand if you want to improve your accuracy at long distances. In this article, we will explore the differences between MOA and MRAD.
MOA is an angular measurement that is based on the degree of a circle. It is a measurement of the size of an angle, and it is expressed in minutes of angle. One minute of angle is equal to 1/60th of a degree or approximately 1.047 inches at 100 yards. MOA is commonly used in the United States and is the preferred method of measurement for many hunters and long-range shooters.
On the other hand, MRAD is also an angular measurement, but it is based on the metric system. MRAD stands for Milliradian, and it is a measurement of the size of an angle that is equal to 1/1000th of a radian. MRAD is expressed in milliradians, and one milliradian is approximately 3.6 inches at 100 yards. MRAD is commonly used in Europe and is the preferred method of measurement for many military and law enforcement agencies.
One of the main differences between MOA and MRAD is the size of the units of measurement. MOA is larger than MRAD, which means that it is easier to make small adjustments with MRAD than with MOA. For example, one click of an MRAD scope at 100 yards will move the point of impact by approximately 0.36 inches, while one click of a MOA scope at 100 yards will move the point of impact by approximately 1.05 inches. This makes MRAD more precise than MOA, which can be advantageous for long-range shooting.
Another difference between MOA and MRAD is the mathematical calculations required to make adjustments. MOA is based on a 1:60 ratio, which means that 1 MOA is equal to 1.047 inches at 100 yards. This can make calculations more difficult, especially when working with odd distances. On the other hand, MRAD is based on a 1:1000 ratio, which makes calculations simpler and more straightforward.
Finally, it is important to note that both MOA and MRAD are accurate and effective methods of measurement, and the choice between them ultimately comes down to personal preference. While some shooters prefer MOA because it is more familiar, others prefer MRAD because it is more precise and easier to work with. Ultimately, the best choice depends on the shooter's experience, the type of shooting they are doing, and the tools they are using.
In conclusion, MOA and MRAD are both important measurements for long-range shooting, but they differ in their units of measurement, precision, and ease of use. While both measurements have their advantages, the choice ultimately comes down to personal preference and the shooter's experience. Regardless of which method you choose, mastering the use of either MOA or MRAD can significantly improve your accuracy and precision at long ranges.
