You'll actually do better when it comes to dealing with long range if you forget what the distance is at 100yds and just remember that it is an angle that you're talking about. It's much easier to talk about come-ups a extended range if you think about them in either MOA or mils rather than 24.6 inches of drop since that represents a different angle depending on the range.

+1. Yup, what he said. ↑
