Actually, i don't know what the drop would be at 200 yard, for this load, if the rifle were sighted in at 100 yard. The chart shows the calculation for a 200 yard zero, for what i guessed is the approximate muzzle velocity for this load.










The chart shows the bullet need be 5.48" high at 100 yard to hit zero at 200 yard. Theoretically what i would do to shoot this rifle/load at 200 yard, is twist the elevation dial up 22 clicks, after it was sighted in at 100 yard. This isn't actually what i did for this particular shooting, because the rifle was kinda already sighted in at 200 yard. What i did do, was fine tune the 200 yard zero, and one day, i turned the elevation dial down 22 clicks to see where it hit at 100 yard. The bullets hit close to zero at 100 yard, but seemed a touch high.

If the scope was left to be zero at 100 yard, i don't really know where the bullets would land at 200 yard.

Ever since the summer 2011, when i started using custom CDS dials from Leupold, i sight all the rifles in at 100 yard. To shoot further, i twist the CDS dial up to the yardage engraved on the dial. For loads without a CDS dial, i twist the elevation dial up the calculated moa. Actually i am quite ignorant of bullet drop, and wouldn't try to shoot deer at long range using a 'guessed holdover'. Following is a chart showing bullet drops when a 100 yard zero is used.












It appears the answer to your question is 11". Sorry, i took so long to arrive at the answer, but i didn't think of how to find it, until i ran out of gas.
