Target height

Here's the proposition:

A 22 rimfire bullet of 40 grains (BC.157) exits the muzzle at 1050 f/s from a rifle held 60" above grade.

At what height does a target need to be set so that the bullet striking it at 100 yards impacks the bottom of a berm 200 yards from the muzzle?

Thanks

Next time we are at the range, remind me of this ... we can do some measurements of our 22 F-Class target frames and calculate from there. We built them after some impact testing; however, we were shooting prone and not from the bench ....

The real problem at Magnolia in using basic ballistic data is that the firing line is elevated so that must be taken into consideration ....

I took this into consideration when estimating 60" as aiming height above grade (includes a 30" high bench plateform, another 6" for rifle rest and 24" as the dropoff). I could be off a skosh or three.
