    Is there a chart out there that shows the hold off for an AR-15 with a 25 meter zero at various distances? For example, aim 5" high at 100 meters, 2" high at 200 meters, etc.

    Try this..... http://www.ar15.com/content/page.html?id=659

    But obviously it is only good for one bullet weight/bbl length, or I should say 55gr at a specific velocity.

    the .mil was using a 25 meter zero for years- prior to my most recent deployment to Afghanistan they have changed to a different zero(still done at 25 meters cause that is the range set up but using the bottom 1/3 of the target to more closely approximate a 50 yard zero) apparently the old 25 meter zero, especially with the m855 green tip ammo caused point of aim engagement at the closer ranges inside 200 meters to impact very high with the impact difference at 100 being like 1 foot high above point of aim. Most now advocate the 50 meter zero for this reason- the point of impact at various ranges is much closer to point of aim out to 300+ meters

    I like the 50y zero. It come back down around 200-225y and is only +/- 2" from zero-~250y

    For general purposes don't use a 25 yard zero as its the same as a 340 yard zero and the bullet impact is 4 to 6 inches high at 100 yards.
