Ya man if I spent 3,700 on a scope Id be shot and buired by my wife.
As stated get a Laser Range Finder for distance.
For optics get something that has the ability of external adjustments. Vortex has a very good bang for the buck. I have turned 5 people to the Viper PST and we have shot them at distance and they track true. If you know the distance then with a good ballistics program will get you VERY close to actual numbers. Confirm those numbers by going shoot at distance. After that the up and down is a given. All that is left is to make your wind guess.
Dishonored stick to what you know. Spewing bad information is bad for everyone. Once you get past a few hundred yards you need to be more and more precise with target distance because the danger space is getting tighter all the time.
The easiest way to range a target is with a laser range finder. You adjust the scope by turning the turret on top (called the elevation turret) to compensate for the amount of drop that the bullet you're shooting will fall at the distance that you ranged. That is the easiest and most efficient way to adjust a scope for long range shooting. Trust me. I've tried chanting to it, whispering sweet nothings into the objective....I've tried negative and positive reinforcement, but none of that works so don't let anyone tell you different. Direct stimulation of the turret is best...

I recommend spending some time/money and go here:

I've been shooting a while and do work with optics all day every day and I still learned my money's worth.
But I'm agreed with Barney, get a good entry level scope like a Vortex PST, a laser range finder, and maybe even download a ballistic app on your smart phone. They are pretty simple to use. Range, compair to your dope card, dial/hold. That would be the easiest way to go I can think of.
