MOA vs MIL Rifle Scopes (2025 Mega Guide): What They Mean, How They Work, and Which One You Should Buy

---

Quick Take

• MOA (Minute of Angle) ≈ 1 inch per 100 yards (technically 1.047”). Great if you think in inches/yards.

• MIL (Milliradian) ≈ 3.6 inches per 100 yards / 10 cm per 100 meters. Great if you think in decimals/meters.

• Neither is “more accurate.” They’re just different rulers for the same angular corrections.

• Consistency wins: Don’t mix a MIL reticle with MOA turrets. Pick one system and stick with it.

• Hunters often pick MOA; PRS/military/long-range shooters often pick MIL. Your call—just be consistent.

MOA and MIL, Explained

Picture this: you’re on the bench, first shot is low and right. Your spotter says, “Up one MOA, left half.” If your turrets click ¼ MOA per click, that’s four clicks up and two clicks left. At 100 yards, 1 MOA ≈ 1 inch, so you just moved your point of impact about 1 inch up and ½ inch left. Easy, right?

Now imagine your spotter speaks in MILs: “Up 0.3, left 0.2.” Most MIL turrets move 0.1 MIL per click, so that’s 3 clicks up and 2 clicks left. At 100 yards, 0.1 MIL ≈ 0.36 inches (about ⅓ inch). Decimal math, tight adjustments.

Bottom line: MOA and MIL are just angular units (like inches vs centimeters on a tape). Neither kills more deer, punches tighter groups, or magically shrinks the wind. You do.

The Math

• MOA

  • 1 MOA = 1/60th of a degree

  • At 100 yards: 1 MOA ≈ 1.047 inches (everyone rounds to 1”)

  • At 200 yards: ≈ 2” | at 500: ≈ 5” | at 1000: ≈ 10.47”

• MIL (MRAD)

  • 1 MIL = 1/1000 of a radian

  • At 100 meters: 1 MIL = 10 cm

  • At 100 yards: 1 MIL ≈ 3.6 inches

  • Common turret: 0.1 MIL per click (≈ 0.36” @ 100 yds)

Conversion:

• 1 MIL ≈ 3.438 MOA

• 1 MOA ≈ 0.291 MIL

You don’t need to memorize conversions. Pick a system and live in it.

What Should You Choose?

Hunters (deer/elk/varmint): MOA usually feels natural. Zero at 100, learn your drops in MOA, call wind as “¾ MOA.”
PRS/Field matches/Long-range steel: MIL is the lingua franca. Spotters talk in tenths. Stage briefings are MIL-centric.
New shooters: Either works—pick the ecosystem you’ll train in. If your mentors/club call in MIL, go MIL. If your crew is inch/yard, go MOA.
Rule #1: Don’t mix reticle and turrets in different systems. Match-match-match.

Common Mistakes (and Easy Fixes)

• Mixing systems (MIL reticle, MOA turrets) → Fix: Buy matching or replace one component.

• Using exact 1.0″ for MOA at 100y → It’s 1.047″. At hunting ranges it’s fine to round, but be aware.

• Dialing when holding would be faster → Learn your reticle holds for speed stages.

• No dope card → Print a dope card in your unit; keep one in MOA or MIL (not both).

Real-World Zeroing & Holds (Walk-Throughs)

Scenario 1 – MOA zero:

• Rifle: .308 Win, 100-yard zero.

• First group = 2” low, 1” right.

• Correction: Dial +2 MOA up, -1 MOA left. That’s 8 clicks up, 4 clicks left on ¼ MOA turrets.

Scenario 2 – MIL zero:

• Rifle: 6.5 Creedmoor, 100-yard zero.

• Group = 3.6” low, 1.8” left.

• Correction: Dial +1 MIL up, +0.5 MIL right. That’s 10 clicks up, 5 clicks right on 0.1 MIL turrets.

👉 Both get you to the same point of impact. The math changes, not the physics.

---

Training Plan: Get Fluent in Your System

• Print a dope card in your unit (MOA or MIL) — tape it to your stock.

• Practice holds, not just dialing. PRS stages reward speed.

• Range buddy system: Make sure your spotter speaks the same “language.”

• Apps: Ballistic AE, Strelok Pro, Hornady 4DOF let you choose MOA/MIL and learn faster.

FAQ

Q: Which is more accurate, MOA or MIL?
Neither. They’re both angular units. Accuracy depends on glass, turret quality, and the shooter.

Q: Can I convert MIL to MOA easily?
Yes. 1 MIL ≈ 3.438 MOA. 1 MOA ≈ 0.291 MIL. But conversions slow you down. Pick one system.

Q: Should hunters use MIL?
Hunters can use either. MOA feels natural for “inches at yards,” but MIL can be better for rangefinding and wind calls in decimals.

Q: Can I run a MIL reticle with MOA turrets?
Technically yes, practically no. It’s confusing and will cost you hits. Always match.

Final Thoughts

MOA vs MIL is not a fight—it’s a translation issue. Both will put meat in the freezer, steel ringing at 1,000, or protect your crew.

• If your hunting buddies call in inches, go MOA.

• If your PRS squad calls in tenths, go MIL.

• If you’re new: pick what your mentors and gear support.

Consistency is king. Choose your ruler. Learn it. Shoot it. Own it.
