Are you sure your scope is mounted stress free, by that I mean more often than not when you put a rail on 700 actions and srew one end down the other end has a gap on the other end meaning no way can it not have a banana shape when tightened down.
I know your using Talleys which if I remember correctly are 2 piece which means the same principal when you torque the scope down. I'm not saying it's your problem but it's something to look at and eliminate it's why anymore I dont care if there NF or spuhr mounts it can very well be the actions mounting points I bed the rings and rail if needed which is atleast 75% of the time

Agreed. Most of the woes that I’ve read in this thread that could be attributed to erector malfunction are, IMO, likely to be caused by receiver induced mis-alignment stress on the scope tube and thus relatively easily addressed by bedding bases and rings. Alleviating such variables is accuracy 101.

So I have a Leupold VX6 on my CA 6.5 PRC. Rifle shoots really well, I’ve got a load worked up that is consistent and I’m feeling good about this fall until the tall target test. When I dial up, I get a 1.5-2” shift to the right. I ran the test 4 times. Made sure the target was plumb with a level, used levels to mount the scope, and even tried rotating the scope counter clockwise (since the shift was to the right). Nothing has worked. No matter what I try, when I dial up, I get a POI shift to the right. I know there are a lot of things that can cause this. I’m using Talley one piece rings for the mount. I’ve remounted the scope twice. I’ve got a NF I’m going to put on it to see if it is the scope or the mounts, or the receiver. Anyone have any other suggestions? Would a bore sighting tool show the discrepancy?? I got the scope from Holland’s with his reticle in it. I’m going to call them on Monday to see what they have to say. Is it possible I just have a bad scope?? Thanks.

Sometimes the reticule is sticky try winding it vigorously back and forward on both elevation and windage this worked for me, it drove me nuts when it happening to me,, hope this works for you.

Hey, just curios.... how far from bottoming out are you when dialed all the way down? I ask this because if you’re bottomed out your reticle could be hitting the inside of the scope tube, then as you dial up, it takes the pressure off and allows it to track straight up. Because it seems to me, once you start dialing up, it’s about 2.5 moa right and stays 2.5 moa right?

When I dial up the 30 MOA, I still have another 8 that I can go up. That seems like a decent amount of room that is still left, but I don’t know if it really is or not???

How about when you’re zeroed... at 100.... how far down can you go?

I’ve had this same thing happen, except it was in the “up” direction

I had a similar experience with a Leupold and found out the reticle was canted 3.5 degrees left. Finally bought a Nightforce NXS and and never looked back. Now I own seven different models of Nightforce scopes and the next one I buy will be another Nightforce. Nightforce Scopes replaced "Nightmare" scopes and all track beautifully.

Doc was 38 MOA from max elevation which should put a VX6 about in the middle when zeroed for 100 yards. (75 MOA total elevation on those) so I am back to square one and have no clue why it was doing this.
I will say this much, I was not there and did not see it so if it is working correctly now then guess what? It is good to go for now. I suspect there are variables we don't know about that caused some portion of this. I thought for sure he was all the way down but then it would be nearly 75 MOA before he ran out of elevation.

Some people wanna blame the scope just because it says Leupold just like when a gun wont shoot the barrel is the first thing that gets blamed.
Theres only one way to find out for sure and that's to take all the mounting variables out of the equation or have a scope checker with a frozen scope.

I am viewing on my phone, but the original post does not really look like a horizontal shift? Looks more like you have horizontal in your groups.
Are you sure it isn’t something mechanical in your setup? Shooting position etc?
