I am lost here, you numbers are way, too broad. BTW, .2 is finer then .5My comment/response to all this is, everyone thinks they need .2-mil for accuracy, where the human eye/brain is very capable in determining/measuring accurately in smaller incriments with larger reference points, such as .5-mil. You guys need to learn to use your reticle, and how to bracket targets with reticles that have .5 or 1-mil hash marks.
Yes, having something that provides .1 or .2 scale for accurately measuring a know size target to estimate range is helpful, but let's be honest, how many people actually do that?
Most people shooting PRS type matches want target distances handed to them on a silver platter. Or they're shooting at a square range that have targets set at 100-yard increments.
The goal of any competent user of a MIL reticle for ranging is down to .05 mil. that's as fine as one can go. you can not visually see any more detail then .05MIL. With a tolerance of .05MIL Between 500-700yards caliber dependent, will result in and average of 10-20% failure rate on first round impacts. As distance extends, so does the first rate impact percentage.
Running a simple chart you can see the error in distance:
Distance in yards | .05MIL +/- error |
500 | 9 yards |
550 | 9.9 yards |
600 | 10.8 yards |
650 | 11.7 yards |
700 | 12.6 yards |
The human error jumps a bit more from 750-1000yds in range estimation.
