hensoldt rf reticle

[wilecoyote]

I've buyed an old Bundeswehr milsurp 8x30 Hensoldt OD rubbered bino_ inside the right ocular I can see some kind of range-finding reticle, numbered from 0 to 40 on both sides_I know nothing about that, of course_ someone can explain me how use this reticle, even if unlikely I will be in need to call an arty support , or where to find some reference to learn something about that?_ any info will be welcomed!

What is it that you don't understand? It's like a mildot reticle.

I don't understand how pratically employ it_ I understand that it can seems silly, but here we can't freelly practice in open spaces, I'm not a hunter, and due to the limits of our shooting stands, (max.300mt.), I've never needed nor used a mildot reticle, therefore I know nothing about that_ If you say that it's like a mildot reticle, I will be motivated to learn more about that_ Thank you very much for your answer !

OK. It's pretty simple. The reticle is used to measure angles and the unit is milliradians, i.e. 1/1000 of a radian. You might know the relationship between angle, radius and length of arc when using radians but if you don't then here it is: angle = length of arc / radius of arc.

That is the background. The practical use is that you can use the reticle when spotting and say that the impact is 5 mils (miliradians) left and then the shooter adjust the fire. The scale in the binos is a bit too coarse for small targets and adjustments. Another use is range estimation.


This is the formula for calculating the distance: width in metres x 1000 / width in line = distance in metres

Calculating the target width:

width in line x distance in metres / 1000 = width in metres

It doesn't have to be meters but it's easier if you use the same unit for both target size and distance to target....
