<rg1>Here is basic data from JBM ballistics:
Assuming a 1.5" sight height and zeroed at 200yds:
50yards +.4
100 +1.3
150 +1.2
200--zero
250 -2.5
300 -6.4
350 -11.8
400 -18.8
450 -27.8
500 -38.8
This doesn't take into account humidity, altitude, and temperature etc.

<rg1>This is using JBM Ballistics and showing basic data for being 2" high at 100 yards:
50 yards +.7
100 + 2.0
150 + 2.3
200 + 1.4
250 - .8
300 -4.4
350 -9.5
400 -16.3
450 -25.1
500 -35.9
This shows that you would be actually zeroed at about 235 yards.

Bill MJeff,
You can download a ballistics called "Point Blank" for free. I seems to work well and is fun to play "what if" with....
