Im looking into buying a scope with a mil reticle.

I have a couple questions regarding mils and wind drift.

I have done the shooteready thing and score between 96 and 100 using the mil/mil. Im saying this because I understand how to use the data.. my question is how to come up with the wind data in the first place?





What is the best way to determine wind drift using MILS?

I notice on all the ballistic calculators..etc, they give wind drift in inches.

Do you then convert all those numbers to mils?




Is there a better way?

Most us military data is for 308, but some sniper data books available on the open market will have other calibers. I have no idea what you are shooting. Also, sometimes the major ammo companies will provide this info to you. Just keep in mind that any set of data you get is only acurate for that EXACT round- ie, data for a black hills 77 gr (MK262) will not be the same as for a winchester 55 gr type round. Also, twist rate and barrel length affects velocity, which is also a key component in the equation.

Ok.



While i was reading I came upon the JBM ballistics program.

Seems pretty intense.




What are some good ballistic programs that give windage in MILS?




Any for the iphone?
