Wes,
No, I hadn't seen or heard anything about a long range rifle that the rotation of the planet has to be taken into consideration. The latest Sniper Rifles I have seen pictures of and read about have an effective range of about 1 1/2 miles in the hands of a good shot and they have to consider gravity. Even the short range missiles ( 100/250 miles ) don't have anything in the specs I have seen that say anything about the rotation of the Earth. But I don't get all of the latest books and papers on this stuff any more so I would guess it could be possible.
My idea of using the rotation of the planet to good effect would to be an anti gravity round or shell that you could just hand in the air, point it toward the direction the Earth would be rotating the target to it, and set it to explode when the target gets there.
