    Locutus,

    Sorry when I downloaded it the colums shifted to the Left!

    Tried a second time to physicaly move them but when I downloaded them again the same results. So you will just need to shift them to their correct position to the Right and maybe print them off!:confused:

    I haven't tried this program, GNU Exterior Ballistics Computer. It is very highly rated. It also has the capability to compute windage and atmospheric pressure.

    Need some input guys. Just sighted my irons in. I didn't have a tool so I just sighted the rear. Wow the front is off bad. I'm at the 300 mark just to get it hitting 1 inch below zero at 100 yards. It's hitting about 1 inch high at 75 yards.is that about right. Anyway I'm hitting a sheet of paper now at 100. Is that ok with an ak?

    Download a ballistics program for Excel. Enter you figures, highlight the columns you want, and tell the software to make a graph. In this way any changes you need to make dependent on your situation your graph can be updated. The one I found I also hid the columns I do not need. Found several links to it on various websites. If you do not have MS Office, Open Office or Libre Office could work just as well.

    Even got it formatted to work on an IPad. Have not tried on my Android as the screen is so much smaller. Also as you enter your information you can do a "save as" and rename the file for whatever ammo you are using by manufacture or load type.

    Not sure how to add a link to the file. I'm using the IPad at the moment an all of my links are on the laptop. A search for ballistic, spreadsheet, excel should bring up a few links.

    The steep drop is why the 25/200 zero is nice... just a couple inches high at 100 and a couple inches low out at 275ish
