HI, I have a question on scopes. When zeroed in at a hundred yards with the parallax set at 100, does the impact point also move when changing distances. In other words does changing the parallax to 200 hundred yards does the crosshairs compensate and your holdover is already done? It's not easy to test this since because nothing must move, but it does appear be on target when adjust the parallax. Let me know, I'm not young, so please be simple when answering.
