It really just depends on how much adjustment range your scope has, and how much you need to adjust. If it is off by 12 inches at 10 yards, there is an issue, and you will use up the majority of your scope's clicks. Find the mechanical zero of your scope and set it to center if you want to see how far you are moving the inside of the scope. If it can be adjusted and holds zero, you should be fine. If you are using 95% of the clicks and that bothers you or it won't hold zero, you will need to work something out. Any rifle can have issues that look like droop, as the mounts/grooves on the receiver can be misaligned as well, along with the alignment of the barrel. My .223 had nearly 20" at 100 yards, a bolt action, and my target scope wouldn't have had enough clicks. So work to the mounts or rings was necessary without buying a new scope with more adjustment range or adjustable rings/ or a 20 moa mount to point the scope downward. If your rifle just shoots a bit low, you are likely just fine. Custom milled rings are also available.
