I recently purchased a Zeiss Conquest 3-9x50 and mounted it on my weatherby vanguard 7mm. While trying to bore sight it I bottomed out the dial on the scope and the crosshairs remain about 5" above where I need to be. I have low rings and bases on the scope and it is almost touching my barrel so I am unable to get it any lower that way. I'm just wondering if anyone can help me fix this. As it stands now I have an expensive scope that is basically useless to me. Please help!
Zeiss Conquest 3-9x50 zeroing issue

Sounds like your rings are tipping the scope slightly down. Height of the rings won't make any difference but if one is slightly higher than the other it will. I'd try different rings.
EDIT: After rereading your post...have you actually shot the rifle yet? If not, bore sighting is a pretty inexact science when it come to elevation. I've got a couple bore sighters that will get me pretty well dead on side to side but if they get me within a foot elevation wise I'm happy. A little more info would be helpful.
Have you shot it?
If not, what are you bore sighting with?

I have tried three different sets of rings and bases, in different heights. I have had the same issue with each, but the lower I get with them, the closer it gets to zero. I have tried shooting the gun and was hitting 6" low, and cant move the crosshairs anymore to correct. I have never had an issue like this before with any other gun/scope combo I have mounted.
How many clicks does the elevation turret turn from one extreme to the other? If it's turning maximum MOA and the crosshairs are moving, you've got a ring/rifle problem. Ring height will have very little effect. Ring alignment will. Is this a new rifle? Are you certain the objective lens isn't contacting the barrel?
You could always borrow another scope and try it and that would eliminate one variable.

I will count clicks when I get home later today and post it. It isn't a new rifle and I tried another scope on the rifle with the same rings and it is fine. The only difference is the other scopes are 40mm obj and this one is 50mm. The lens isn't touching the barrel (see pic).
i would say change the rings for slightly higher ones
or try cutting a piece of margarine tub to fit in the rear
bottom ring to slightly pack the rear end(eye piece) up a didge
then try to re zero.
not sure how much room you have for maneuver with the front end

Is that front ring 100% on the tube or is it partially on the bell for the objective lens? It would only take a couple thousands of an inch to throw the scope out of alignment. You may not even notice it but there would likely be a small mark on the scope when you pulled the ring off. I can't tell for certain but is there contact with the base and eye piece? One of the issues with putting a scope with a short tube on a very long action with regular bases and rings is that you have no room to move the scope back and forth and it's easy to get a slight incline or decline without even noticing. Personally I'd use a different ring set up. You've got zero room to adjust your eye relief and I suspect you may not even have 100% tube contact.
Rings and bases are both Leupold STD. The front ring is 100% on the tube, I thought the same when I first mounted the scope. You are right about the long actions, there is basically no room to wiggle them around. I actually just bought a Browning X-Bolt 300 WSM and will be putting this scope on it. Maybe with the little bit of extra room it will help, I just wanted to try to resolve the issue beforehand if it was a simple problem.
This is the first impression I got too when I opened up this thread and saw the OP's photo.

It would seem the scope doesn't have enough adjustment for that ring/base setup, which could be due to the scope internals themselves, the Vanguard's receiver or the base/ring set-up. Perhaps the base holes were drilled slightly canted in the receiver? An infrequent problem with Savage, I haven't heard about it on Vanguards though.
I would count the clicks, according to Zeiss you should have 74.88" of elevation adjustment. I'd also check the product numbers on the bases themselves, I've had a wrong one in a factory sealed Leupold package.
What brand/height were the other rings and bases you tried?

I have seen a similar issue with another Conquest, but that scope had the issue with windage, not elevation. We actually swapped that Conquest for one of my Conquests, and that scope appeared to be much better centered, and sighted in easily. In the end, we went with a set of bases that were adjustable for windage, and the owner hasn't had any problems since. It appears that somehow, the erector system wasn't perfectly centered in the tube.
