[QUOTE="woods, post: 190371, member: 6042"] Hey ST Thanks for the link and I found this in CatShooter's post "But modern scopes with internal adjustments do not... and the cross hairs in scopes can be 2 to 4 degrees out of plumb to the spindle faces, so you can't use the cross hairs to set up the bubble, (which is what EVERYBODY does). If the bubble is not true to the spindle faces, then when you crank in elevation, you also crank in a little "windage" because the hairs also crab to one side or the other." I don't have a bubble but I do believe that cant is my problem. I will rotate the scope and let you know. Let me see if I can post a picture [IMG]http://img.photobucket.com/albums/v663/bwestfall/DSCN0290.jpg[/IMG] Hey, it worked! I had already shot the 400 yard mark on another target, but you can see where the 2 shots at 200 were a little right, at the 300 mark they were noticeably to the right and at the 500 yard mark even further. Be a great way to get the scope reticle level - shoot at your 100 yard zero, click 30 up and shoot, see if the POI of the 2 groups were vertically aligned. [/QUOTE]
