Calculating Mils

Hi there, I am trying to calculate a cheat sheet for 50m increments using the mils in my scope. I am having problems figuring out with conversion equation I need to be on with my mils. The two equations are as follows:

With a bullet drop of -7.8cm at 200m
7.8/2= 3.9 Mil Holdover

With a bullet drop of -7.8cm at 200m
7.8/20cm= 0.4 Mil Holdover

Help is greatly appreciated.

Do a google search you will find countless posts on this, I think there are even some calculators out there specifically for this.

I've found them, but there are many different calculators and these are the two most used. Just trying to figure out which one works. I think the first is using MOA and the second is figuring the mils.

1 Mil is approx. 3.6 inches at 100m, or 7.2" at 200m. If you are 7.8 cm, or abot 3" low at 200m then you hold 1/2 a mil.
have a look:

This is by far the best page I found and it worked very well for me.

Mills works really well when you take your range in meters and not yards. One mill is one meter at 1000 meters. As far as converting by the cm, this would take some calculator time.

1 mil is 10cm at 100m... 20 at 200m etc. You need to determine the size and spacing of the dots, ovals or hash marks in your scope. From there you can develop hold overs. Don`t forget if you have a second focal plane scope you have to be at the right magnification for it to be accurate. For most that`s max power, but some the old Leupolds were goofy and it was around 11X.

Hopefully your adjustment dials are in mils as was otherwise you will have to do a conversion if you want to do a dial up.
