[QUOTE="KYpatriot, post: 1188007, member: 48028"] Your welcome. Unfortunately for me Im better at physics than shooting. Ill try to upload some pics of what Im saying...Here is a snapshot from a North pole view, two points are drawn equidistant from the pole, therefore directly east /west of each other. Notice the card edge is parallel to the table edge.[IMG][URL=http://s642.photobucket.com/user/kypatriot_bucket/media/image_zpsqqkmz75w.jpeg.html][IMG]http://i642.photobucket.com/albums/uu146/kypatriot_bucket/image_zpsqqkmz75w.jpeg[/IMG][/URL][/IMG] Ok next I have laid a straightedge along the two points, representing the path of a bullet. Notice that by chance it is at a slight angle to the table edge: [IMG][URL=http://s642.photobucket.com/user/kypatriot_bucket/media/image_zpsftmbzrnw.jpeg.html][IMG]http://i642.photobucket.com/albums/uu146/kypatriot_bucket/image_zpsftmbzrnw.jpeg[/IMG][/URL][/IMG] Now, I will rotate the earth, counterclockwise for the Northern hemisphere, while holding the straight edge still. Notice the angle of the earth has changed, the earth rotated. The left dot has rotated away from the straightedge (bullet path), the right dot has as well and is now under the straightedge. The angle of the straightedge is unchanged.
