Hi, I am not sure if any of you experienced this before but this happened to me a few times before. Line up a target, dial in, pull the tigger and bang on. Spotter calls out another 5 targets the size of 2" square blocks and they get pulverised, just as easy. Very precise shooting and I'm very pleased with myself. Then the sun pulls out of the clouds and suddenly I am not hitting the targets anymore. I checked my water bubble and my gun was canted. I straighten it and the target disappear out of my focal plane. The only way I could see the target was to cant and my bullets are going over at 1 O'clock high. Same thing happened a couple of weeks ago but the opposite. I was shooting well when the sun was bright. As soon as the light condition changed, I had to fiddle with the knobs. And that makes it worse.... I am using a Premier Reticle 20x50x50mm and the same thing happens at 20x or 50x magnification. I tried cranking it down to 20x and still can't see the target unless canted. Of cos I could reset myself, reposition the rifle and it'll work but I can't figure out why light would affect it so much. Any help grately appreciated.
