I was shooting on the 100 yard line this past sunday, temp was around 45 (which is real warm, compared to earlier weeks). Anyways, I was shooting my 6.5, which has a Weaver T-36 on top. The heat mirage was so bad, I could barely get a bead on the target. I don't remember ever having this problem during the summer, so I'm at a loss. Could it have something to do with the sun/warm weather and the still frozen ground? I noticed slight mirage with my 8x Leopold(edit: it was barely noticeable, not even a problem), but it was horrible with my 36X scope. Any thoughts?
