An In-Depth Study for Shooters. It's a new updated version from the one I wrote in 2007. I simplified it, made it less cumbersome I think and easier to read. I hope you can learn from it and become a more knowledgeable shooter. Feel free to download it and pass along. Thank you. Bob Simeone (Bags)

And the new shortened, less math intensive, version for those not wanting that:

I am new to the mil/mil scene. Having always used MOA systems, i find myself in need of a simple range and wind formula for mil based turrets.
The link above did not work.

Am I right to assume that about 17.4 mils equal a degree? Just wanting a reference when talking to non-shooters?

Yes

1 degree=17.45329 mrad or mils

The above posts are correct. There are 6,283.185307... mils in a circle and 360 deg in a circle. Therefore, 6,283.185307 / 360 = 17.45329 or 17.45 or 17.5 mils per degree. (See pages 1-5 of the link below to see why there are 6,283.18 mils in a circle).

Steelbenz, i have no use for the mildot master. I am bright enough to make the calculations myself. I just dont want to spend all afternoon figuring a solution for a shot.

I am looking for something simple to replace
Range in 1/100ths x windspeed mph ÷ constant = moa adjustment for wind. One could just take the moa and divide by 3.5, but i think there is a better way.

The Mil-dot Master is not for people not bright enough to make the calculations themselves.  It is a force multiplier tool for people who do something a lot… just like the old Jeppesen flight calculators or a slide rule… makes the math process faster.  You can always download an "app" like Shoot or Shooter or Strelok or Applied Ballistics or Ballistic… I have, and use, them all.  I also use the Mil-dot Master, as do many of the really good shooters I know.  Don't know anyone too smart to use one of the available tools.  If you have all the time in the world… by all means… do the math.

My point was that simply going to a crutch or tool for a skill you should possess without first attempting the gain the knowledge to perform said task in the abscense of said tool is foolish.

Kinda goes with that whole "the more you sweat in peace, the less you bleed in war". Or maybe this one, "train for the worst, hope for the best".

More interesting to me is that i asked for a mil based wind formula to replace my old moa formula.
What i got back was "get a mil dot master".
Maybe the old slide rule has been revamped since i saw one when they first came out. If i am wrong let me know. Im not too cool to admit wrong.
But since when does the MDM help in wind calculations? Much less mil based?
Seems as though all it did was give RTT.

Again, i am looking for a quick wind formula that gives the hold offs in mil. God help me if i asking for a formula for movers or maybe a loophole formula!!

Just wind in mils.

Sadly, its youtube for the win.



(corrected for hyperlink)

That's great for learning, for going through all the "intimate details".  There are much easier ways to get this done.  


Try this one:


Or… go back and READ CAREFULLY:

first you want to do the math, then you don't 

3.438 MOA = 1 Mil
.3438 MOA = .1 Mil

1 MOA = 0.2909 Mil
1/4MOA = .072725 Mil

The best answer given yet here is found on this youtube video.
I have used mil/moa scopes for a couple decades. Finally in this new millenium i have moved to mil/mil. So now is the time to revamp math. Accuracy First teaches this stuff very well. I would like to be familiar prior to hitting their ranges.

Agreed. However when one does open his mouth, the lack of an original thought usually gives him away!
