Hi, lepirt:
Looks like you have to sight in at short range. That's not the best because what the computer says doesn't anyways happen on the range, sometimes it's all you can do. It's not really that simple, since you didn't say if you're shooting with irons or a scope. Anyhow, let's give it a try. Now 2" high at 25 yd. is away too high, that gives a zero at 440 yd. with a scope 1.5" above the bore and a zero at 360 yd. with irons 0.7" above the bore.
Scope at 100yd = +10.5", at 200 yd. = +16.6"
Irons at 100yd = +8.0", at 200 yd. = +10.7"
Dead on at 50 is better. With a scope you're back on again at 110 yd. and -4.2" at 200 yd. With irons your trajectory peaks at 50 yd., -0.7" at 100 yd. and -6.6" at 200 yd.
Try for +1.6" at 50 yd. That should put you +2.6" at 100 yd. and dead on at 200yd.
May I suggest a couple of ballistics programs you can play with yourself? You can download PointBlank at
http://www.huntingnut.com/pointblank.html or you can get to JBM by clicking on Ballistician's Corner on the left side of this page.
Don't be afraid to holler if you have any problems.
Bye
Jack
