MIL vs. MOA Reticles — Which Are Better for Tactical Tasks?

MIL or MOA — which angular measuring system is better for target ranging (and hold-offs)? In a recent article on his PrecisionRifleBlog.com website, Cal Zant tackles that question. Analyzing the pros and cons of each, Zant concludes that both systems work well, provided you have compatible click values on your scope. Zant does note that a 1/4 MOA division is “slightly more precise” than 1/10th mil, but that’s really not a big deal: “Technically, 1/4 MOA clicks provide a little finer adjustments than 1/10 MIL. This difference is very slight… it only equates to 0.1″ difference in adjustments at 100 yards or 1″ at 1,000 yards[.]” Zant adds that, in practical terms, both 1/4-MOA clicks and 1/10th-MIL clicks work well in the field: “Most shooters agree that 1/4 MOA or 1/10 MIL are both right around that sweet spot.”

Zant does note that a whopping 94% of shooters in the Precision Rifle Series (PRS) used a mil-based reticle. However, Zant says: “This does NOT mean MIL is better. It just means MIL-based scopes are more popular.” Zant agrees with Bryan Litz’s take on the subject: “You can’t really go wrong with either (MIL or MOA). They’re both equally effective, it comes down to how well you know the system. If you’re comfortable with MOA, I wouldn’t recommend switching to MIL. I have a few MIL scopes but primarily because they’re on rifles used for military evaluation projects, and that community is now mostly converted to MILS, so when in Rome….”

We recommend you read Zant’s complete article which is very thorough and is illustrated with helpful graphics. Here are the key points Zant makes in his MIL vs. MOA analysis:

MIL vs. MOA — Key Points
There are a handful of minor differences/trade-offs between MIL & MOA, but there are no inherent advantage to either system. Most people blow the small differences WAY out of proportion….Here are the biggest differences and things to keep in mind:

  • Whatever you decide, go with matching turret/reticle (i.e. MIL/MIL or MOA/MOA)
  • 1/4 MOA adjustments are slightly more precise than 1/10 MIL.
  • MIL values are slightly easier to communicate.
  • If you think in yards/inches the math for range estimation is easier with MOA. If you think in meters/cm the math is easier with MIL.
  • When your shooting partners are using one system, there can be some advantage to having the same system.
  • Around 90% of the PRS competitors use MIL.
  • There are more product options (with ranging reticles) in MIL.

Range Card Print-Outs
Zant makes an interesting practical point regarding range card print-outs. He suggests the MIL System may be easier to read: “You can see in the range card examples below, 1/4 MOA adjustments take up more room and are a little harder to read than 1/10 MIL adjustments.”
