" I get 48 clicks "
Pretty close to my number 50 that I pulled from my a**.... but enough that you miss by 3.5" at 700 yards. (2 clicks = 0.5 moa * 7 = 3.5")
The difference is probably the 200 yard number. If you get a 2" drop at 200 yards, that would be 4 clicks (not 2) and then numbers are the same. 48 clicks.
The main lesson is that the distance that you zero at does not "reset" the yardage to 0. ie the (700-200) was the source of the error. The math is actually (dope for 700 - dope for 200) or (52 clicks - 4 clicks) = 48 clicks.
Remember moa is really an angle, not any set distance... it just happens to be very close (within ~4%) of 1" at 100 yds.
