MOA VS MIL: Which One Is Better?

Minute of Angle (MOA) versus Milliradian (MIL) is often treated like a Ford vs Chevy debate (or Coke vs. Pepsi). People think it’s a preference. It’s not. This is less about preference and more about understanding the system. A better analogy isn’t two brands of razors — it’s one person using a razor and another using a rock. One is simply more efficient once you understand why. Most people just haven’t been exposed to the right explanations.

THE BASIC MATH

Let’s get the simple math out of the way.

• MOA = 1.047 inches at 100 yards

• → ~10.5 inches at 1,000 yards

• MIL = 3.6 inches at 100 yards

• → 1 yard (36 inches) at 1,000 yards

Both are forms of angular measurements. Both scale to the distance you are shooting. But this is where MIL starts to separate. As distance increases, MIL becomes easier to work with.

THE “INCHES VS METERS” ARGUMENT (AND WHY IT’S WEAK)

One of the most common arguments for MOA is:

“If you think in inches, use MOA. If you think in meters, use MIL.” That sounds logical, but it doesn’t hold up. You can convert either system into whatever unit you want. That’s not the advantage. The real advantage is how usable the system is under pressure.

THE PIZZA ANALOGY

This is how I explain it in class. Think of:

• MIL = Costco pizza (big slices)

• MOA = Domino’s pizza (small slices)

The rough conversion is about 3.5 MOA to 1 MIL. So, if you need to make an adjustment:

• You can eat one big slice (MIL)

• Or 3.5 small slices (MOA)

Both get you there. But one is faster and simpler to manage.

WHERE MIL CLEARLY WINS

1. Communication and Target Leads

If you’re calling corrections or leading a moving target:

• “Hold 1.2 MIL”

• vs

• “Hold 4.2 MOA”

MIL is faster, cleaner, and easier to process. That matters when things are happening quickly.

2. Reticle Simplicity

MIL reticles are easier to read and use. Typical MIL reticle:

• 1 MIL increments

• Half-MIL hash marks

At further distances, your holds might be:

• 7 MIL

• 10 MIL

• 12 MIL

That’s easy to see and track. Now compare that to MOA:

• 25–35 MOA holds at distance

• Much smaller increments

• More clutter in the reticle

It becomes harder to quickly identify and hold accurately.

3. Turret Management

Most MIL scopes:

• ~10 MIL per turret revolution

That often gets you to 1,000 yards in one revolution, and back to zero without confusion.

MOA scopes:

• Often requires multiple revolutions.

That’s where problems happen:

• Losing track of revolutions

• Thinking you’re back at zero when you’re not

• Sending follow-up misses because of it

MIL is simply easier to manage.

4. Ranging and Calculations

Without going too deep, ranging targets (“milling”) are designed around MIL reticles. If you’re using MOA, you’re adding:

• Extra steps

• Extra conversions (again, ~3.5x)

That slows everything down.

REAL-WORLD EXAMPLE

Early in my career (around 2004), we were running optics like the Leupold Mark 4. Those scopes often had MIL reticles and MOA turrets. That meant learning both systems. That’s not a disadvantage — it’s actually valuable. But once you understand both, most shooters who evolve tend to move toward MIL.

WHERE MOA MAKES SENSE

In Benchrest or F-Class shooting, finer adjustments are advantageous. This discipline is about shooting the tightest group possible, not simply hitting a target at various distances. The optics for this discipline follow suit, offering high magnification and fine reticles. These optics also use 1/8 MOA adjustments, which equate to 0.125” at 100 yards. Pick the optic and measurement based on shooting discipline.

THE BOTTOM LINE

MOA works. It’s not wrong. But MIL is:

• Easier to communicate

• Easier to see in the reticle

• Easier to manage on the turret

• Easier to use under stress

That’s why the military — and most modern precision shooters — have standardized around MIL. Once you understand both systems, the choice becomes pretty obvious.
