help with mil-dot zeroing

remingtonman_25_06 · #1 06-16-2008, 02:29 AM

Well I broke down and bought a sighton S1 3-9x40 w/mil-dot for my triple deuce. Am quite pleased with the optical quality, should work out great.

I'm not real familiar with the mil dot, and someone with a little more knowledge could probly help me out. What I'm trying to do is based on my drop, figure out where those mil-dots are going to hit dead on out to (rough estimate anyways.) I figure I sight dead on at 200, maybe 100 and use the next mil down for a "xxx" dead on hold, so on and so forth...

How does one go about figuring this out??

Is there a program to simplify this??

Thanks to any and all help.

The easiest way is using a ballistic program.
1 mil = 3.6" at 100 yards = 36" = 3 feet = 1 yard at 1000 yards.
In the following example using standard see level conditions, 100 yards zero, 300 RUM, 210 BERGER at 3000 ft/sec muzzle velocity. 2.5" scope hight.

Or you could zero at 725 Yards, that'd be about 100 yards zero using the top most mildot.

This is a pretty powerful program that will perform these calculations in both, the desk top version and the pocket pc version.

If you're interested you can check it right here.

I cant seem to find out how or where to plug in the numbers to get what I want. I dont wanna pay 150 for the program either. If I gave you my info, could you possibly run it when you get time??

Shooting a 50g NBT @ 3300, BC is like .240 or so, zero at 200. sight height 1.5"

You might find this easier: http://www.jonaadland.com/Hunting/Ba...Calculator.xls

Put in your info, click on the "Drop Charts" tab and you'll see it gives them in both MOA and Mils. Also sites like JBM, ( JBM - Calculations - Trajectory ) etc, can be set to Mils to do the same thing.

Eaglet,
I tried to run this for Remingtonman and post it here. But I can't figure out how you posted it here. Would you tell me please?
Thanks

Just think of it the same way you figure out your clicks to change your zero. Instead of 1 click equaling .25 IPHY, it will be 3.5 IPHY for each mil. Half a mil will be 2.75 IPHy.....
