Or are you saying I will need to be 10.5 high at 100 to be dead on at 600 yards?? Sorry, I am a bit confused.
I know that I am 8 inchs high at 100 yards to be dead on at 500. That is what my ballistic chart say's, and it was verifed by shooting. Thanks, Tom.
Yes, 10.5" high, however there are a lot of other variables that can affect your drops, but that should get you close.
To match the drop you mentioned at 500yds, I had to lower the muzzle velocity in Exbal. You will probably see a little bit more drop than the 10.5" above; probably closer to 11.5" high at 100yds. That means that you will need one more MOA than the data listed above. Remember 1 MOA at 600 yards is 6*1.047" =6.28"
I'm pretty confident that you will be somewhere between the 10.5" and 11.5" high at 100yards to be dead on at 600yds.
There are a number of things that make calculating drop charts a non exact science. One of the biggest, is that although chronographs are reasonably good at measuring relative velocities, they're not great at measuring absolute velocities. For example, a chrono might tell you repeatedly that your load averages 3250 but in fact it might be 50-100fps faster of slower. Also, your elevation, the humidity and the temperature also have an affect (not to mention the vertical component of wind, even if its from the side).
