The first thing you will need to do is isolate if it's a rifle issue or a scope issue. I would start with the scope first. If you have one available or you can borrow one then I would try a different scope on the rifle. I would start by taking the existing scope off and check the rings and bases to ensure that they are tight. If everything checks out, then take the bottom rings and attach them to the bases. You will then take the scope and place it in the bottom rings what you will be looking for here is that the scope rings and bases are aligned correctly. If it doesn't just lay right in there (you do not want to be forcing or pressing it in) then you are going to need to do some lapping. (if it's not way out of alignment) If it's way off then you are going to need to get some new rings that will allow you adjust the windage via that route. As mentioned above the Burris signature rings will take care of this and Leupold , Burris and other companies make the dovetail style base that has the rear base that you can use to adjust the windage. I'm not sure if you have access to a boresighter or not, but you can also mechanically zero the scope and look through the boresighter to see how far off it is. I seen many rifles that came from the factory with the base holes out of alignment, but I haven't seen any that were so far out the above mentioned rings couldn't correct the problem. If you rule out that it isn't a scope or mounting issue then I would contact Ruger, they will take care of you. I'm not sure what kind of scope you have, but if it turns out to be a bad scope most companies will work with you on correcting that problem as well. I haven't personally seen one of these rifle that don't shoot! Feel free to send me a PM if you have any questions.
