    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"

    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.....

    Hey thanks a ton Eaglet! That will help me out a lot! I would like to see what it would be like if zeroed at 100 yards as well. When you get time anyways. Thanks again.

    Eaglet,
    I'm sorry, I wasn't clear on my request, I know how to post the picture. What I wanted to know is how you got the picture in the first place. I can't see any way to make a copy of the Reticle Hold page.
    Thanks.

    What you do is that when your done and everything is on the screen of your computer, I'm using Windows XP, and should be the same for any windows from Microsoft, once you have on the screen what you want to post, press and release the key, on your keyboard, "PrtScrn" ; what that dows is that it takes a picture of your screen and saves it in the clipboard menory, now, you open a photo editing program, if you don't have any use "Paint" that comes with Windows and go to edit and click on "Paste". Now you will see your whole screen as a picture. Crop the section you want and save it. Now you have a file that you can post.
    If you need more help just PM or e-mail me. :)

    I have that scope on a rifle that I do not use much, BUT, and this is a biggie, as I recall Sightron made up their own Mil-Dot size!
    In other words you will have to tweak your calculations and not use true Mils! It is not that big of a deal, just shoot and make a cheat sheet.
    Mine is several years old and they could have corrected this by now, so go out to 100 yards and mark 2 dark lines 1 mil apart and see if there is any magnification that matches up with a Mil.

    PS This is old but probably worth reading:
