MOA vs Mil Scopes

Duration: 18:40

This video delves into the fundamental differences between Minute of Angle (MOA) and Milliradian (Mil/MRAD) scope systems for long-range shooting. It clarifies that neither system is inherently superior in precision, with MOA often favored by American shooters for its intuitive 1-inch-at-100-yards measurement, while Mils align better with the metric system. The discussion also covers the importance of First Focal Plane (FFP) versus Second Focal Plane (SFP) reticles for maintaining accurate subtensions across magnification ranges.

Quick Summary

MOA (Minute of Angle) is roughly 1 inch at 100 yards, while Mil (Milliradian) is about 3.6 inches at 100 yards. Both are angular measurements used for scope adjustments, but Mils are base-10 and align with metric, while MOA aligns with imperial units. Neither is inherently more precise; choice depends on shooter preference and system alignment.

Frequently Asked Questions

What is the difference between MOA and Mil scopes?

MOA (Minute of Angle) is roughly 1 inch at 100 yards, while Mil (Milliradian) is about 3.6 inches at 100 yards. Both are angular measurements used for scope adjustments, but Mils are base-10 and align with metric, while MOA aligns with imperial units.

Is MOA or Mil more precise for shooting?

Neither MOA nor Mil is inherently more precise; they are just different measurement systems. Precision depends on the scope's quality, turret adjustments, and the shooter's skill. MOA is often preferred by American shooters for simpler mental math with yards and inches.

What is the advantage of a First Focal Plane (FFP) scope?

An FFP scope's reticle scales proportionally with the magnification. This means the subtension values (MOA or Mil) remain accurate at any power setting, allowing for consistent ranging and holdovers across the entire zoom range.

How do Bullet Drop Compensator (BDC) reticles work?

BDC reticles feature specific markings designed to compensate for bullet drop at predetermined distances. They are typically calibrated for a particular caliber and load, offering holdover points rather than a universal measurement grid like MOA or Mil.
