I like the quick little ballistics program you offer here. I have one question about the input data regarding height of sight from barrel. Is this the distance of the center of the crosshairs from the barrel? Or distance of the bottom or top of the scope from the top of the barrel? Or am I messed up altogether and don't understand? I used the center of the scope/crosshairs and the trajectory turned out about like I expected. Merganser

Center of the crosshairs above the center of the barrel.
