You hurt my brain.....but MOA...Just for the sake of curiosity, which do you prefer in a rifle scope reticle, MIL (milliradian) or MOA (minute of angle)? I'll add a single-choice poll with this thread so people can see how it shakes out with the NWFA membership, the three choices being MIL, MOA, or Either One/No Preference.
For reference, a Minute in MOA is 1/60 of a degree. Since there are 360 degrees in a circle, there are 21,600 minutes (60 X 360 = 21,600). In practical terms, one minute of angle roughly equals one inch at 100 yards, or 10 inches at 1000 yards (more exactly, 1.047" and 10.47" respectively). MILs* are another unit of measurement for a circle, but based on the metric system. One radian is equal to 57.3 degrees of a circle. Do the math and you'll see that makes a full 360-degree circle equal to 6.2827 radians. As most of you are probably aware, as a prefix "milli-" means one-thousandth, so a milliradian is one-thousandth of radian, or 57.3 degrees divided by 1000, which is close to half of a degree for each milliradian (.0573 to be exact). Practically speaking, this means one MIL at 100 yards is roughly 3.6" inches, or more appropriately in metric terms, 10 centimeters at 100 meters.
*Sometimes you'll hear "MRAD" used instead of MIL, but the two terms are completely interchangeable. MRAD is just another way of shortening the word milliradian.
