[QUOTE="bruce_ventura, post: 885995, member: 34084"] Calculated bullet drop values are not very sensitive to small errors in sight height value. 20 MOA of base tilt amounts to a very small height change across the base (about 0.030"). An error in the sight height value of 0.030" changes the point of aim only 0.30" at 1,100 yds, assuming a 100 yd zero. I typically use the height at the center of the objective lens because this lens positions the optical axis of the scope. [/QUOTE]
