I would think if I get too much slope, I wouldn't be able to zero at 100. Maybe I am wrong in that thinking. This is my first long range rifle, so I'm not sure.

You are right about if you get to much MOA bases, you will not be able to get a 100 yard zero.
What you are looking for is a base that will keep you in your desired range and in the middle of the scopes range.
If it is a dedicated 1000 yard rifle and will never be used less than 600 yards then I would
recomend a 15 or 20 MOA base. if you want to shoot 100 to 1200 yards you will need a 10
MOA base. beyond that you will need a 20 to 30 MOA base
Look at your drop chart and after adding a 10 MOA base verify that it will be within the range
of your scope and load.
10 MOA will increase the elevation of your scope to 85 and 10 above normal.(you still have
75 MOA it is just 10 MOA higher).
Scopes are most accurate in the middle of there range (say, 20 to 55 on yours).
