Once you've worked up a good consistent load, crank up the elevation on your scope to maximum and see how high you hit at 100. This will tell you what your maximum range will be with a center hold. You will need to be able to adjust up to 36"- 40" high at 100 to ensure that you can shoot point of aim at 1000 with a variety of bullets.
As a very rough guideline you need to be:
+40" at 100 for 1000 yard zero, (about 32" with my rifle)
+26" at 100 for 800 yard zero
+18" at 100 for 600 yard zero
+12" at 100 for 400 yard zero
To actually reach 1000 yards, you might need to shim the rear of the scope or purchase a 20 MOA base. Ideally your lowest scope setting will be consistent with a 100 yard zero, but don't fret if its not provided you can dial in the range you want.
When you shoot, keep records of the date and weather conditions, your load, the range, your position, and your called shot vs your POI. Print out the drop tables from an online ballistic program like JBM, then as you shoot, replace their data with your own. This can be recorded on an index card with the appropriate scope setting for each range. You can then laminate and tape the index card to the butt of your rifle.
