Does any one know of any websites where you can practice ranging given certain criteria. This would be a great resource to help get used to using mils and MOA. Just curious Thanks!!

This might help. Ordered my disc after trying the demo.

Re: mil dot ranging quizzes
sweet I struggled at first but started getting it. What is your compensation for the wind its not quite a complete crosswind kind of a tail wind what would be the proper way to compensate? what is the easiest way to convert bullet drift in inches to MOA? Just trying to do as much practice as possible to get it down till I can practice outside when the weather gets better. Thanks

Re: mil dot ranging quizzes
(Range/100)x Wind Velocity = MOA
_______________________
Constant
Range(meters) Constant
100-500 = 15
600 = 14
700-800 = 13
900 = 12
1000 = 11
This is what I use. But I am sure that there are many more experienced shooters on here that can help a little more.

Re: mil dot ranging quizzes
I like the MIL demo, since its quartering wind use wind velocity * 0.75 then * either 0.1 or 0.2 mils (whichever one for the range).
Should be able to do the same thing with the MOA demo and use MOAs instead of MILs in the formula.

im fully understanding the elevation adj. but the windage im having trouble with, do i take my range in yards and divide by 100? then multiply by my wind velocity to get my moa?thats what i was doing and its not coming out right?

Re: mil dot ranging quizzes
The formula above is not rendered well. In addition, the constants listed are for wind holds in MOA. I don't do MOA, I do mils.
<div class="ubbcode-block"><div class="ubbcode-header">Code:</div><div class="ubbcode-body ubbcode-pre" ><pre>
(range in yards/100) * wind (mph)
wind hold(mils) = ---------------------------------------
constant
</pre></div></div>
The constants I use are:
<div class="ubbcode-block"><div class="ubbcode-header">Code:</div><div class="ubbcode-body ubbcode-pre" ><pre>
Range(yards) Constant
<= 500 45
600 43
700 41
800 39
900 38
1000 37
</pre></div></div>
However, that's a rough approximation for my load. If you want one more accurate, use a ballistic program set up for your load and a 1 mph full-value crosswind, and work the formula backwards:
<div class="ubbcode-block"><div class="ubbcode-header">Code:</div><div class="ubbcode-body ubbcode-pre" ><pre>
(range in yards/100) * wind (mph)
constant = ----------------------------------
wind hold(mils)
</pre></div></div>

Re: mil dot ranging quizzes
You forgot to divide by the wind constant for the distance you are shooting at. Look at the formula 3* posts up again. See the division part, with the constant?

Re: mil dot ranging quizzes
Lindy,
How do you figure the wind value into that thar formula? Just divide mph by value?

Re: mil dot ranging quizzes
If I understand your question, the answer is to put the wind speed in miles per hour in the formula where it says "wind (mph)".
Added:
Oh, it occurred to me you may be asking about full and half-value winds.
The formula is for a full-value wind. If you have a half-value wind, multiply the wind hold by 0.7.
It's not intended to be precise - just fast.
