I am not going to say these numbers are going to be exact, but it will get you real close without knowing all conditions. Zeroed at 100 you will be 3" low at 200 and 11.1" low at 300.

For that load though I tend to agree with ridge runner. If you have the ability to zero for 200 yards that is what I would do. with 200 zero you would be 1.6" high at 100 and 6.5" low at 300.
