Yup what charlz says it what I was about to mention there are lots of ballistic programs available on the net. That and 1.5" high @ 100 is where my 308 and 30-06 are also zeroed to shoot point of aim at 200 knowing what my muzzle velocity's with a chrono so good luck. btw I am impressed your daughter is such a good woods girl/hunter well done dad! :thumbsup:
