If you have an iphone or android phone there is a nifty app called Strelok.
You input the relevant data, and it will provide you ballistic tables telling you the drop for a given angle.
For popular scopes on the market, you can find your scope in the program and it will show you holdover for a given distance. It will also tell you how much to adjust your scope or how much to holdover. Lots of features, you can program in and save various bullet weights at different velocities.
It is also free, at least it is on android, so it is at least worth checking out. Good user interface and a good free ballistic calculator.
