Seeing as how you asked for clicks?...this is what I've come up without having all input data needed. Won't have an explanation as to the who's and whys but from what I gather, your in the process of learning ballistics. Its not rocket science, really it's pretty straight up once you understand it. There's a lot of info out there and once you get it you'll realize just how easy it really is.
Its interesting as to what everyone has come up with. Everybody's using a more or less factor which is what I'm doing.
100 - zero
200/ 7 clicks
300/17 clicks
400/30 clicks
500/43 clicks
...sorry no 600.

As I mentioned, not going into detail because there's easier ways, I've simply tried to answer your question.
