    Thanks for the great summary.
    I use the center of the dot as the apparent size of the dot will change with varying intensity, illumination, and background color.

    Will you make this thread a Sticky or add it to the AR15 Zeros and Trajectories Sticky?

    100 m zero guy here for the reasons stated. However, I initially used it because I got an ACOG, and it was calibrated for a 100 m zero.

    Regarding irons, I like the Revised Improved Battlesight Zero, but you need the A2-style drum rear sight to implement it. This scheme provides the ability to use the small aperture with an approximate 100 yard zero, the large aperture in the standard 50/200 range, and the small aperture again from 300 yards out using the drum.

    F2S, great explanation on how it works. I did the ground work for the 100m zero on our 25m indoor range and did a quick field test on it out at an LE 3 gun match last Saturday. The 25m ground work put me dead on (pure luck I think) and I was able to shoot fairly competatively, at least in the rifle portion. I am going to be working to get all of our folks swapped over to the 100m zero on thier rifles, in this line of business it just makes to much sense.

    +1 on making this a sticky.

    You sold me. I'm all for less guesswork, less variables, less math.

    Thanks for taking the time.

    Well written and the graphics clearly illustrate the point. This is typical of why I pay attention to what F2S posts

    For those running with an EOTech, I found this quick range estimation diagram. Basically, if your target is standing inside your 65moa ring, your range is roughly 100m.
