I came up with this idea today while contemplating scopes with build in range finders. Imagine a scope with a build in computer and laser range finder. The range finder finds the range and then passes that info on to the onboard computer, which has it's own ballistics table and then adjusts the crosshairs automatically. Adjusting for windage would be more difficult, but still possible. There could be some exterior module that measures the wind then passes it on wirelessly to the scope's computer. I'm sure the different technologies required to do this are out there, but I'm just not sure if anyone has put them all together yet. And if someone did, it would cost as much as a new car.
