I've got a question into Nikon pertaining to this (will share when/if i receive answer) issue.

Ammo and so forth aside. Not worried about hold overs/unders at the moment.

On my Nikon, i have a vertical line of circles and lined spaces. Being as each has a known quantity, there SHOULD be a way to figure this.
Youtube vids make it out that "no! it cant be done!" I call BS. Yeah. A mil dot scope is going to be great for that job. I get it.

I dont have a mil dot scope tho.

Worst comes to worst, I'll take a day at the range and spend much of it NOT shooting. I think i can put a 1" grid target at 100 yds and measure said circles and spaces. I can convert the moa to mils.
I see no reason why this wouldnt work.

Any suggestions for "science" lol?
