Ok, this is what he was doing. For the mil hashes, he started with one MOA and multiplied it by 3.438. Then he looked up the corresponding MOA from the Ballistics readout (hence the five yard increments) and matched the corresponding distance. That is the first hash mark. For the second, he multiplied 3.438 by 2 giving him 6.87 and found the closest MOA which is 6.86. the corresponding range is 225 yards, ect. For the half mil hashes, he used 1.7 instead of 3.438 and did the same thing. </div></div>
I ran the dope directly in MILS so there is no conversion math at all to do.
Chiller correctly points out the unorthodox nature of what you are doing.
In that although this technique will work within a specified framework of conditions, it is not very adaptable, and you are going into it knowing that it will be imprecise, especially at longer distances.
The mainstream technique is to zero at a distance inside the effects of wind and use the reticle for holdovers accordingly.
It's taught and approached the opposite way you are doing it.....
Let the distance of the shot be the first factor in the creation of a firing solution, not the lines on the reticle with predetermined yardages in mind.
If you're zeroed at 500Y, and a target suddenly appears at 650Y with no time to dial, You hold over the number of MILS on the dope card listed for 650 and hit the target.
