Nikons spot on calculator on their website has listing for almost every single load available, you pop it in, then zero your scope for what ever range you like, and it tells you where its going to hit out to every yardage you want.

My experience with it is things were only off 1-2 inches at most out to 500 yards. basically tells you 200 yards, top of second ring, 400 yards, bottom of 400 yard ring and so on. Its pretty spot on
