I am not a Mil-Dot expert, however, this site right here is worth a look. http://www.mil-dot.com/Mil_Dot_User_Guide.htm#MilDots

It covers the basics all the way up to putting it to use in a training simulation. (Not a dirty G word.)

The basic formula is, target size (in inches) x 27.778 divided by Mils read = yards to target. There are other variations of the formula for meters and such.

For example, a 12" tall target (times 27.778 = 333.336) which reads 2 mils would be 166.668 yards away.

Good luck with the site. If there are any other similar sites out there, let us know.

I am having a problem with the mil dot. I have been playing around with the (shooterready.com) program. On the first level the target was a 12"x12" target. It looks like it is 1.7 mil. So I did the math, .333 target (yards) X 1000 /1.7 mil= 195.8 yards. I know I am missing somthing big. Because the target is 420 yards away, after I shot it : :lol: . Somebody please tell what I am doing wrong.

 

Officer,
Erik's got you taken care of, but I'll give you another example so you can practice.
1rst you must know how tall your target is in inches!
Let's say you know your target is 6 feet tall. That = 72"
The 27.77 is a constant number. It's what you use to multiply with always.
Take 72 x 27.77 = 1,999.44
Now looking through your scope measure how tall the target is in mils. Let's say while looking through the scope your target measures 1.5 mildots tall. Now you divide 1,999.44 / 1.5 = 1,332.96. Rounding up your target is 1,333yds away.
Here's one more: Target is 3ft tall - 3ft is 36in
36 x 27.77 = 999.72
through the scope target is 2 mildots tall
999.72 / 2 = 499.86
target is 500yds away.
Hope this helps

Ok thanx. I was going to ask what the 27.778 was for, I saw a ton of other sites that where telling me somthing else. Thanx guys!

 

yeah multiplying 27.77 is much quicker and easier than doing the whole 1,000 / 36. It just takes that step out to make it less confusing. Some use other constants like the one above. You just have to remember how tall your target is in inches and multiply by the constant (27.77). Then you only have to divide once (size in mils through scope). With practice you can guage if its 1.3mils tall or 1.7mils and so on. The more precise you are with your mil number the more accurate the range will be.
I like doing the math myself (when its easy). Have fun! any other questions, just post away!

I did what you guys said and I think the shooterready demo is not working right. It keeps putting me off by over one hundred yards. I may be doing it wrong too.

 

I was reading on another site that I google and they said that in the demo the range cards are off.

 

I use exbal from Nightforce.
If you want I can send you some ballistic cards through email. I just need the caliber and type of bullet.
ex: .308cal 168gr Sierra Matchking bthp
When I send them you can just print them out. I have the range set up to show drop values every 25yds. I also make them for every 10deg. of temperature change. I cut my cards out and fold them at the 500yd line. The cards end up being 3in x 2in. I then laminate them and hang them from my scope. Some tape them to thier stocks. Just let me know, I don't mind making them as long as there isn't 6 or 7 loads you want me to make

Ok that would be great. .308 168gr Sierra Matchking bthp. I will PM you with my email address.

 

How about the mods make this a stickey?

I have the shooter ready DVD make sure that you mil the target on 10x because that is a simulated Leupold SFP scope and the mils are only valid at 10x that may be what is throwing you off.

Just watch the mil dots closely on the target as you change the scope power from 10 to 20 and back to 10

I only use it in 10 power. I do the math right, which I have check with other people to check it also and it is right. It may have a problem with the demo verson of the program.
