I just got a brand new Ziess conquest 3-9x50 and mounted it on my new Browning Abolt 30-06. I absolutely love the scope and gun. I only have one problem.

Went out today on the farm to sight the gun in and found a bit of a problem. The first two shots indicated the gun to be about 3 inches right and 3 inches high. So I moved the turrets 12 clicks to the left and 12 clicks down. Shot twice more - and the groups never moved not at all. I then moved left another 4 clicks and down 4 clicks - tapped the scope a little to try and help settle things, then shot another two times. The group came down to the right up/down level - but still over too far right (about 1 1/2 inch too far). I ended up shooting about 15 shots, moving the turrets over to the left about 2 clicks for the remaining shots - all with no noticable difference in group placement. What is the problem? Any help would be greatly appreciated.

What type of rings and base are you using? and are you sure the scope is on correctly...ie up@down turret on the top    right -left on the right side?

I have Leupold rings and base.  The scope is on correctly as far as I know - it was mounted at the gunshop by the gunsmith and boresighted.  Using the top turret for up down and turning it in the direction of the U/R marking for UP adjustment. using the right side turret for right/left direction - turning the turret opposite of the U/R arrow for left alignment.

And the rings are dove tail type I presume? if so it /they may be mis aligned causing the scope to be tweaked not that they are ...just possibilities .

the condition you describe could be the result of the erector tube at the end of it's travel potential. the turrets will still rotate but the tube isn't moving. just one possibility.

What Dave said or possibly the ring closest to the power selector is too tight.

 to check the ring alignment you can use a 2' broom stick or copper pipe this will tell you if they are alined and that they are lined up with the bore.

It almost seems as though the erector assembly is defective. I would look at the mounting first. Sometimes the guy at the gunshop isn't the best person to mount your new scope. If nothing is wrong there, I would suspect an internal problem. This isn't something you normally hear about with Zeiss, but it's not out of the realm of possibility. Mistakes happen. I say check the mounting, and if all is correct, and not too tight, have Zeiss look it over.

+1 on the comments posted by Dave & Roy.

I would give you my two cents worth, but then you would probably have to give half to the gov't and what good is one penny

Checked the mounting, and all seems OK. The rings were torqued to 30lb with the torque wrench the guy used. Is that too tight? What is the golden standard there?
 
Also, one question you guys asked was if I was shooting at 100 yds. I was not, I was shooting at around 50 yards - would this matter? If so, how much?
 
thanks so much for your help. It is greatly appreciated

     I believe Leupold recommends 15 inch pounds(2-3 ft lbs). I doubt that Zeiss recommends twice as much. Could be your problem.

If you are shooting at 50 yards then you need to move the adjustments twice as much.  So 4 clicks would only move it 1/2 inch at 50 yards instead of 1 inch at 100 yards. 
I would also back off your ring caps torque.  15 to 18 is all that is needed for ring caps, any more than that can cause stress on the scope tube which could lead to problems like you are having.

I seen a scope that was mounted by a "gun store"Whatever to a Ruger rifle.  I was at the range shooting and a guy was trying to hit paper at 35 yards but he kept shooting over.  I had a bore sighter so I went over to help him.  As I was walking over I could see a huge problem.  The scope ring on the front was way taller than the one on the back.  I could literally see his scope tube bending because the rings were so misaligned and way to tight.  I am guess they were at least 40 inch lbs, it took a lot to get them loosened.  I guess Ruger rings are different heights front to back and the "gun shop guy" had used the same height ring for both front and back. 

So ya, be careful with those all knowing "gun shop guys" Whacko

That is pretty much my thoughts. The only person I trust to mount my scopes now is me. If your rings were that tight, it may lead you to trouble. If this doesn't fix the problem, you still may have a scope issue.

AMEN!  I saw a rifle with Talley rings in my local Bass Pro where they had reversed the bases, using the taller base up front, shorter in back, the exact opposite of the step down on the receiver.  You could see the scope wasn't parallel with the rifle.  I mentioned this to the gun counter and they insisted the mounts were installed correctly.  Many of these "gun shop guys" are low wage hourly employees whose prior job was working the electronics dept at Wal Mart who don't have a clue.
 
BTW, yes, Ruger rings for an M77 are different height front to back, the taller one at the back.  On a #1 and other Rugers with a quarter rib, they are the same height front and back.

Trigger's got the right idea.  I can't pay someone to spend as much time and attention to detail as I will aligning/lapping rings and mounting scopes.  By the time I bore sight and adjust the reticle to perfect level I've invested a couple of hours and I know it's done right.

 
I agree this sounds like a mounting/lack of adjustment accounting for 50yds.  If not Zeiss will take care of you.
