Issue with a scope
 
I just bought a new savage 93r17 in .17 HMR and I got this scope as well. I brought it to the range today to zero the scope, but when it came to getting the elevation I couldn't get it to adjust anymore. It was shooting about 2 inches low at 50 yds. The elevation was maxed out. After I was done shooting I talked to the people at the store and they told me that I had it mounted correctly. Does anyone know why this scope would be shooting low?

The scope could have been dropped and knocked out of alignment. Or, someone was messing with it and stripped the gears.

It's brand new, just got it today.

You can try getting lower mounts or shimming the rear scope ring a bit.

I have the lowest mounts possible, my objective lense is about a mm or 2mm away from the barrel. The guy at the range did suggest shimming it, but really, a scope that is meant to be used anywhere between 10 yds and 200yds, that can't even zero at 50, it just doesn't seem like shimming should be the answer.

First, check the scope mounts. is there a front and rear mount that may be reversed? Is the space on the ring gap equal left/right? Are the rings fully seated on the mount? If the answer to all is yes, then you may have a defective scope.

The mounts appear to be exactly the same. Now the ring gap was a little bit unequal on right on the front mount. And the rings seem to be fully seated on the mounts.

I don't want to assume anything, but there is a lot more to properly mounting a scope than "plopping" it in the rings and tightening the screws. A good gunsmith typically uses a special kit that "beds" the scope after grinding the rings smooth. I have a kit like that and it takes a while to do correctly. Then you need to adjust both windage and elevation to their approx midpoints. You can't just dial in one then the other. When you turn one, it has some effect on the other. I use a bore sighter to get approx point of SIMM = point of impact, then take to range. You should be on the paper at this point. Adjust elevation and windage together a little at a time. Also the AO (if you have one on your sight) doesn't have much affect on point of impact - only clarity of the target. My 93 shoots minute angle at 100 yards (22 mag) so I know it can be done without shims. Hope I didn't insult your knowledge or abilities.

Should be Point of Aim =

Youre not insulting me, scopes are new to me. How much of an effect does adjusting one then the other have, because I know when I was zeroing that I adjusted the elevation first, and is there a way to actually correct this?
