Trying to figure mills

[Hohn]

There is a major difference in the ability to center groups in the 1/2 moa x-ring at 300+ yards when shooting Fclass using 1/4 vs 1/8 moa adjustment capability. So it is rare to see anything but 1/8 in that application.

So you’re saying you want to see the math?

I have a 223 53 grain V Max loaded and Hornady say's at 500 yards it will drop

35.6 inches (not sure what my load will, just trying to figure this out).

Chart I read said at 500 yards 1 mill is 18 inches, if I held 2 mill high

would I be aproximately at 36 inches at impact, if my load will be

what Hornady say's?

Yes.

To figure inches to mils at any range:
3.6 (inches in a mil at 100 yds) x range in hundreds (536 yds would be 5.36) = 1 mil at that distance.

No, I've played with target statistics enough to realize the assumptions one must make plus the uncertainties of major factors such as wind make this more fun than realistic. In Fclass the gear and shooters are getting so good that the top spots are frequently decided by x count, and in the simplest perspective if you are not centered dead on especially for vertical then you will not be in contention.

Your first sentence contradicts the rest of your post. Either the wind and such matters so much that it overshadows your precision in zeroing or it doesn’t.

X count is indeed the critical tiebreaker at the top levels. And I can demonstrate mathematically that windage variation at 600y —and shooter reading and holding—has a lot more to do with holding the 3” x-ring than does whether your scope clicks are 1.57” (1/4 moa) or ~3/4” (1/8 moa) or even 2.16” (0.1 mil).

Convince fclass shooters that it doesn't matter. The mechanical adjustment capability vs how many shots the statistics require to take proper decisions using that capability are associated, but different aspects. Perfectly centered vertical provides a wider window for windage error.

If you're gonna use mils, stop thinking in inches. It won't work and cause you headaches. If you shoot at a target and you're 1.5 mils low, correct with 1.5 mils. Forget what it might be in inches. Your reticle is a tape measure, use it like one. Mils is super easy, don't overthink it.
