I just bought a new Weatherby Vanguard and went to try and sight it in at some land we own, which is only about a 35 yard range. That is the furthest I can shoot until I find a range, and it is starting to get where I cannot shoot there with the development that is happening up there. I have always mounted my own scope and have never had a problem. I used Leupold mounts and rings. The scope came from another rifle and I know it was working fine. Anyway I was missing the target at 35 yards. I could see that it was shooting to the left. I had to get to 15 yards to hit the target. I moved the scopes windage adjustment to the extreme right and it was still to the left but it was moving to the right. The groups were tight same hole almost. I came home and took the scope off and check the screws on the mounts. I put it back on and tried setting the rifle up so I can look through the bore then through the scope and it looks like it is still off. I got to thinking and on the back ring the Leupolds have an adjustment screw for windage I assume. I think this is my problem, if you cannot tell I did not read the instructions :banghead:. I am going to go buy a bore sighter, I have put off buying one for years now, and see if I cannot get it centered using this adjustment. So I ask you guys does this sound like it is the problem?

You have allready discovered your problem. The rear scope base is indead adjustable to center the scope with the bore of the rifle.
That being said, you will need to be very careful when rotating the front base to be in line with the rear base. DO NOT use the scope as a tool to achieve alienment as it is very easy to damage the scope. It is best to use a dowel rod or other item (aluminum shaft etc) with the same diameter as the scope to pivot the front base into proper alienment with the rear.

YEP, that is your problem. First take your scope and center the crosshairs. do this by moving them all the way to the right and then count the clicks to the other side or left and then divide by 2 and move it back to the right that much. If your scope has 140 clicks from side to side, then move it from one side to the center by moving it 70 clicks. Do this for both windage and elevation. Then try to center the rear ring with the screws of the mount and then put your scope in the bottom half of the rings and see if it is close to the target with the bore on target.
