Mil-dot vs MOA: A Comprehensive Guide

Mil Fundamentals

1. Understanding Mil:
   • One mil (milliradian) is approximately 3.6 inches at 100 yards or 10 centimeters at 100 meters.
   • This measurement is useful for ranging and adjustments due to its angular relationship.
2. Ranging with Mil:
   • To estimate distance using mils, you can use the formula: [ \text{Distance (yards)} = \frac{\text{Target Height (inches)} \times 1000}{\text{Mil Size}} ]
   • For example, if you see a target that is 18 inches tall and it measures 6 mils through your scope, the calculation would be: [ \text{Distance} = \frac{18 \times 1000}{6} = 300 \text{ yards} ]
3. Adjustments with Mil:
   • Each click of most mil-based turrets typically adjusts your point of impact by 0.1 mil at 100 yards.
   • To adjust for windage or elevation, simply convert the wind speed or bullet drop into mils and adjust accordingly.

MOA Fundamentals

1. Understanding MOA:
   • Minute of Angle (MOA) is 1/60th of a degree and roughly equals 1.047 inches at 100 yards.
   • For practical purposes, it is often rounded to 1 inch at 100 yards.
2. Ranging with MOA:
   • The formula for estimating distance using MOA is: [ \text{Distance (yards)} = \frac{\text{Target Height (inches)} \times 100}{\text{MOA Size}} ]
   • For example, if a target is 18 inches tall and measures 6 MOA, the calculation would be: [ \text{Distance} = \frac{18 \times 100}{6} = 300 \text{ yards} ]
3. Adjustments with MOA:
   • MOA turrets typically adjust your point of impact by 1/4 MOA per click.
   • To adjust for wind or bullet drop, convert the measurement into MOA and adjust accordingly.

Choice Tips

1. System Consistency:
   • Choose either mils or MOA and stick with it. This consistency improves accuracy and reduces confusion.
2. Metric vs Imperial:
   • If you're shooting in a metric environment (like Europe), you might prefer mils, while in the U.S., MOA is often more common.
   • Both systems can be used effectively; just ensure you understand the conversions.
3. Fractional Adjustments:
   • Since you prefer fractional MOA adjustments, remember to practice making adjustments in increments like 1/8 or 1/4 MOA for precise shooting.
4. Practice Ranging:
   • Regularly practice estimating distances using both systems. Familiarity will help you transition between the two if necessary.
5. Turret Selection:
   • Since you have MOA turrets, focus on ensuring your adjustments correspond accurately to your chosen adjustments for windage and elevation.

Final Thought

These principles serve as a foundation for effective shooting and ranging. Adapting to either mil or MOA will enhance your precision and overall shooting experience.
