Opinions please. My range faces north and its been hot here in Amarillo. So how much if any will the perceived image with reflective tape or any shiny object used to zero move from 9am to a hot 4pm? Would it be enough to move the poi 3/4 inch? I think so. I took a new thermal mounted on a tack driver to the range 6 out of 7 days last week and the group early in the morning was the only one 3/4 inch LEFT with the sun on the right. I'm probably overdoing this a little, forgive me lol. Maybe the suns got to me.
