MOA Sucks Part III - MOA Is NOT More Precise

Published on May 12, 2024
Duration: 38:15

This video debunks the common misconception that Minute of Angle (MOA) is inherently more precise than Milliradian (Mil) for practical long-range shooting. Instructor Gary from Paramount Tactical Solutions argues that Mil is more efficient and that the perceived precision of MOA is often based on flawed statistical analysis and small sample sizes. The content emphasizes understanding real-world precision limitations, the impact of sample size on accuracy testing, and the practical differences between MOA and Mil in ballistic calculations.

Quick Summary

MOA is not more precise than Milliradian for practical long-range shooting. Tenth Mil offers greater precision than most shooters can utilize, and claims of MOA superiority are often based on flawed statistical analysis of small sample sizes. Real-world conditions and larger shot counts reveal greater dispersion, making small groups unrepresentative of average performance.

Frequently Asked Questions

Is MOA more precise than Milliradian for long-range shooting?

No, MOA is not more precise than Milliradian for practical long-range shooting. Tenth Mil offers greater precision than most shooters can utilize, and claims of MOA superiority are often based on flawed statistical analysis of small sample sizes.

Why is small sample size testing misleading for firearm accuracy?

Small sample sizes (1-5 shot groups) taken under ideal conditions create a false impression of a firearm's true precision. Real-world conditions and larger shot counts reveal greater dispersion, making these small groups unrepresentative of average performance.

What is the difference between accuracy and precision in ballistics?

Precision refers to the consistency of impacts in the same area with a repeated aim, essentially group size. Accuracy is the ability to direct those precise impacts to the desired point of aim.

How can I test if I can utilize the precision of quarter MOA?

Shoot at least five 5-round groups. Analyze the standard deviation of the median point of impact. If it exceeds 0.10 inches at 100 yards, your system's variability is likely greater than the difference between quarter MOA and tenth Mil, meaning you can't fully utilize quarter MOA precision.

What are the advantages of Milliradian over MOA in long-range shooting?

Milliradian is generally considered easier, faster, and more efficient for long-range ballistics calculations and adjustments. It aligns better with modern ballistic software and offers finer adjustments that are more practical for real-world shooting scenarios.
