Well, if you have a picture of a mil-dot reticule in a 10x scope, or if you have one yourself, then a 6' tall man will be exactly 2 mils tall at 1000 yards.

hey mele....

hey mele, just wondering which mils you use? army or Marine? just kinda wondering since i was always taught a standard 6' man at 1000 yds would be 1.9 mils, just wondering if it is the difference in the mil systems or just different schools.

Well, actually, it has nothing to do with USMC or US Army mils, as they both have the exact same measurement for 1 mil. But the mil relation formula makes it pretty clear.

size of target in yards
--------------------------- x 1000 = distance in yards
size of target in mils

we need to do a little algebra to solve for "what size will my target be in mils when my distance is 1000 yards". So, lets fill in what we know

2 yards (6 ft man)
------------------------- x 1000 = 1000 yards (we know it in this case)
size of target in mils.

Now, simplify.

2000
--------- = 1000
mils

we can now cross multiply to get
2000 = 1000 mils

now, simply divide in order to solve for mils.

mils = 2.

Of course, it would have been easier to just remember that a mil is one unit of measure at 1000 units of measure. So, if our units of measure are yards, a mil is 1 yard at 1000 yards, and we know a 6ft tall guy is 2 yards tall, so he would be 2 mils.

Anyway, its just math, so I hate to change the way you estimate your range (if its been working, dont change it!) but a 6ft man would measure 2 mils at 1000 yards.

To answer your question, my bravo has a leupold mk4 10x40mm M3 which uses the smaller US Army mil-dots. (only the dots are smaller everyone, they are still 1 mil apart). But I have other scopes on other rifles that use the USMC 3/4 mil-dots. Either way, they both work equally as well.

ok.. explains it, I always used the 27.777 divided by mils equals range... might explain the diffrence... either way it is .1 mil at a thousand yds, yes a sizeable difference - but not one the average shooter can tell the difference in. thanks for the response, an i'll get back outta sight / outta mind.

So, the the target would be exactly 914.4 meters away, right?

Height of target in inches x 25.4
------------------------------------- = 914.4
Height of target in mils[/u]
