Ok I have a mil scope but if I am shooting at a distance of 63 yds and measure that I am 2 3/4" too low how do I convert the 2 3/4 " to mils to make this adjustment?

I am looking for a formula.
I know at 100yds 1 mil = 3.6 " so 50 yds 1 mil =1.8"

But for oddball distances if I know how many inches = then how to I covert to Mils and make the correct scope adjustment without wasting ammunition?

thanks,

mike
 
If you have a FFP scope just use the reticle. Otherwise you would have to convert MOA to MIL since those are both angular measurements and inches is linear. 2.75" at 68 yards would be 4.044 inches at 100 yards (or 4.044 MOA since 1" is approximately 1 MOA at 100). There is about .3 mil per MOA so .3 times the 4.044 gives you 1.2 mil................Reticle is easier.
 
Easy answer. Get a range finder that spits out the solution. I love the Sig Sauer Kilo systems.
if this helps. Also. Most folks will generally talk Mils with metric system as their both units of 10 but there not both measures of distance. MOA and mils are measuring angle 📐. Anyhow the math is much easier ( .1mil (1 click on most mil scopes) = 1cm @ 100m) or
So..1 MIL (10 clicks) at 100 meters is equal to 10 centimeters. Of movement
1 mil @ 50m is 5 CM
1 mil @ 63M is 6.3 Cm (63mm) of movement or 6.3mm/click

clear as mud.

Or just multiply 3.6 times your yardage and divide by 100 to give you MOA then multiply by .3
 
Maybe this will work at 100 yards you take 2.75" and divide by .36". So that would be
7.64 clicks on the scope.
Now take 7.64 clicks times (100/63) or 1.587. So 7.64 clicks times 1.587 would equal 12.12 clicks.

In other words figure how many clicks it would be at 100. Then if it is less than 100 you take 100 and divide by how many yards you are. Easy example is 50 is half of 100 but takes twice as many clicks. (100/50) = 2. 2 is your multiply factor for clicks it takes at 100 to move it the same at 50.
Past 100 yards you take 100 and dive by actual yardage. East example is 200 yards. It takes half as many clicks at 200 as 100 because each click moves twice as far as it did at 100.
Commit to memory 100/50 = 2 times as many clicks. And 100/200 = 1/2 as many clicks.

Is it a 1st FFP or fixed power scope?
 
Most fixed power scopes are FFP...

As far as the formula goes, just convert your measurements to metric, and Bob's your Uncle.

63yd = 57m

2-3/4" = 7cm

Here is your formula (just cross multiply)

(7 ÷ 57) x 100 = 12.28clicks (or 1.228 mils)
 
If you want to know one mil at a given distance in inches, convert the distance to inches and divide by 1000.

63 yards x 36 inches per yard = 2,268 inches. Divide by 1000 = 2.268 inches per mil at 63 yards. So your offset of 2.75 inches is 1.213 mils (2.75 inches / 2.268).

If you prefer to know mils at a given distance in cm or whatever other unit of measure, the math is the same. Just convert your distance to that unit and divide by 1000.

A mil by definition is simply one thousandth the distance, irrespective of the unit used.

A fixed power scope has no erector so it's irrelevant whether it's a FFP or SFP...

All I'm trying to do is save the OP a bunch of headaches, Not add to them
