I don't touch anything other than adjust the rear bag for the sake of consistency. I like the cardboard idea. But today it wasn't an issue as it was 35°f and I didn't shoot about it to get much of a mirageWell probably not the RL26 then. Do you find yourself refocusing the parallax or anything during the groups? When I am really trying to shoot good groups. I put a long piece of thin cardboard on top of the barrel with double sided tape. I stops heat waves from the barrel affecting the scope image. Barrel heat can cause mirage that looks like your scope is outta focus.
