Best Reticle for Long-Range Scope: MIL vs MOA
When you’re setting up a long-range rifle scope, one of the most important decisions you’ll make is choosing the reticle specifically whether to go with a MIL-based (or mil/radian) reticle or a MOA-based reticle. Both have pros and cons, and the “right” choice depends heavily on how you shoot (hunting, tactical, competition), what units you’re comfortable with (metric vs imperial), and what level of precision and speed you need.
In this post, we break down the differences between MIL and MOA how they work, when each shines, and which kind of shooter or scenario is likely to benefit more from each.

📐 What Are MOA and MIL (MRAD)? Basic Concepts
MOA — Minute of Angle
- MOA stands for “Minute of Angle,” an angular measurement. It’s a subdivision of a degree (60 minutes per degree).
- On a rifle scope calibrated in MOA: at 100 yards, 1 MOA equals roughly 1.047 inches (often rounded to 1 inch for simplicity).
- As distance increases, the linear equivalent increases proportionally: e.g. at 500 yards, 1 MOA ≈ 5.235 inches; at 1000 yards, 1 MOA ≈ 10.47 inches.
- Many scopes offer turret adjustments in fractional MOA (e.g. ¼ MOA, ½ MOA) for fine-tuning.
MIL (Milliradian / MRAD)
- A “mil” (often technically “mrad”) is 1/1000th of a radian.
- Reticles using mils may have mil-dots or hash marks to denote these angular intervals.
- In practical terms: at 100 meters, 0.1 mil typically equals 10 cm (which makes metric-based calculations straightforward); at 100 yards, 0.1 mil ≈ 0.36 inches.
- This angular measure, being metric and decimal-based, tends to simplify range estimation and holdover/wind compensation math.
🔎 MIL vs MOA: Core Differences & How They Affect Long-Range Use
Here’s how MIL and MOA compare across important aspects for long-range shooting:
| Feature / Consideration | MOA | MIL (mrad) |
|---|---|---|
| Unit System | Angular — traditional imperial; good for yards/inches. | Angular — metric-rooted (radians), decimal-based; great for meters/centimeters. |
| Adjustment Granularity | Fine increments (e.g. ¼ MOA), useful for very precise, small corrections. | Adjustments often in 0.1 mil steps; somewhat larger per click compared to MOA, but easier to do quick math. |
| Math & Ease of Use | Familiar if you think in yards/inches — straightforward for short-range or medium-range shooting. | Base-10 math: easier for range estimation, wind-hold, and ballistic calculations, especially over long ranges or when using metric distances. |
| Reticle Clarity / Complexity | Hash marks/dots can get dense; reticle may appear “busy,” especially with fine spacing at long range. | Usually cleaner or more intuitive spacing for range-finding and holdovers; less cluttered at high magnification. |
| Speed of Use / Field Shooting | Slightly slower when making bigger adjustments (many clicks needed). | Faster to adjust for big corrections — useful for dynamic environments, long-range moves, or tactical shooting. |
| Precision Potential | High precision for small corrections, especially in controlled bench or precision shooting settings. | Slightly coarser per unit, but still very accurate — especially effective for long-range precision with less mental math. |
🏹 Which Reticle Works Best — By Use-Case
Depending on what you’re doing, here’s when one system might be better than the other:
Choose MOA if…
- You primarily shoot at short to medium ranges. As some experts note, for typical hunting distances (especially within a few hundred yards), MOA’s simplicity and familiarity make it a solid choice.
- You prefer very fine, incremental adjustments for example, in precision bench-rest shooting, or where minute corrections count.
- You’re more comfortable thinking in imperial units (yards, inches), and don’t want to convert between metric and imperial.
Choose MIL (mrad) if…
- You’re shooting at long range, where quick adjustments for elevation, wind, or moving targets matter. The base-10 mil system simplifies math and reduces error under pressure.
- You prefer metric units (meters, centimeters), or frequently switch between meters and yards.
- Speed and simplicity matter e.g. tactical shooting, dynamic ranges, varied engagement distances. Many long-range shooters and competitors are shifting to mil-based scopes for this reason.
- Your reticle holds hash-marks or mil-dots, making range estimation, wind holds, and bullet-drop compensation more intuitive.
🎯 Why Long-Range Shooters (Often) Prefer MIL — Pros in Real-World Use
- Faster ballistic math & conversions: With mil, many shooters find it easier to convert target size, distance, and required hold-over because the system is decimal-based. E.g. 0.1 mil ≈ 10 cm at 100 m or 0.36″ at 100 yd.
- Cleaner reticle grid: For long-range scopes, mil-grids tend to be less cluttered, making it easier to use for ranging and adjustments without confusing the shooter.
- Popularity among precision/tactical shooters: Many competitive and professional long-range shooters use mil-based scopes, which means more peer support, shared ballistic data, and universal references among shooters.
- Efficient for windage and moving targets: At long range, conditions like wind, target movement, or mirage can change quickly mil’s coarser, faster-to-adjust increments give advantage in dynamic scenarios.
Conclusion
In the debate between MIL and MOA reticles, there’s no single system that universally outperforms the other the best choice ultimately depends on your shooting style, preferred units, and long-range needs. MOA excels in fine, precise adjustments and feels more natural for shooters who think in yards and inches, making it a strong option for hunters and precision bench-rest shooters. MIL, on the other hand, has become the preferred standard for most long-range and tactical shooters thanks to its simple decimal system, faster corrections, cleaner reticles, and compatibility with modern ballistic tools. Whether you choose MIL or MOA, consistency is key: understand your system, train with it, and stick to it. Mastery matters far more than the measurement system itself a well-practiced shooter will achieve excellent results with either reticle.
