[QUOTE="Barrelnut, post: 2296089, member: 74902"] Teri, sorry the "target position change due to angle of the sun" comment I made started to be a distraction on the thread. I would like to speak to it once more though. 1) I found a vid on Youtube, from a Vortex guy, who captures the effect using a spotting scope with a ranging reticle. He captures 9 hrs. of video from 8am to 5pm and then speeds it up. It is easy to see the change of relationship between the reticle and target as the sun moves across the sky. 2) There is also a second vid where an instructor from the Mountain Shooting Center explains the phenomenon as he discusses the importance of a shooting log to capture the rifles zero based on time of day. He then uses a flashlight and scope to explain the effect on a wall. Hope all who found interest in the "sun angle" theory finds them informative. Vids below.
