One things to perhaps try, if you still have the PST mounted on the rings and have not changed the turret settings on the scope, is to re-mount the PST on the newly installed rail on the rifle. If the windage is way off it would seem to point to the new rail/alignment perhaps being the issue. If it remains zeroed I would confirm where the windage is set on the PST and see where the windage zero point lies relative to the center point.
With as many things as you changed at one time it may help you to isolate the potential issue. If you find yourself with about the same 3.8 mil offset then it may just be that you have had the misalignment issue all along and have just become aware of it. Fairly common for receiver mount screws to be drilled slightly misaligned. Good luck!
The PST is now on another rifle that has been sighted in, and that sight in had no notable issues from what I remember. I don't recall needing too much for windage adjustments on the PST. 3.8 mils would have been around 13 MOA, which is more than a full turret rotation on the PST gen I.
Just wondering, did you float the turrets after 3.8 mRad was dialed. If you did not float the turrets you may still be able to get the full adjustment out of it. Theres 14 mRads internally and 10 mRads on the turret. While it may be very uncommon for something like this to happen, the factory zero may have been off. I doubt it, but you may never know.
What do you mean by "floating the turrets"? Does this mean going to both stops with the internal adjustment and then back to the center of internal adjustment?
Did you check to see that the scope was close to optical zero before you put it on? I've seen/had scopes come from a sealed box that were not even close to being centered. Before you mount any scope place the objective flat against a mirror that has good light shinning on it. If the scope is centered you will see but one set of cross hairs. If you are seeing two sets, knob it until you only see one. That will put it close enough for gov work. Then mount it. If the bore sight/bullet hole is still way off at 25 then you have a mount/ring/base/base hole/ barrel clocking/or barrel to receiver issue.
A little confused by this. I place a portable mirror near the objective and shone a light from the side onto the mirror and saw only one crosshair. Not entirely sure if I did it right however.
Questions:
- is this a new rifle?
- new chassis?
- if not, did the prior scope require a similar offset?
Trying to establish whether the mechanical offset could be attributed to rifle/assembly, itself.
There is a possibility that your scope is fine, but the barrel is not square, or somehow being pressured by the chassis. Or, the base rail mounting holes are off center...
just looking at it it from another angle, hope ya get it lined out!
Not a new rifle,
Newer chassis but has been to the range a few times before the new scope set up,
I honestly cannot for the life of me remember if the previous scope needed this much. I have it mounted on a Norinco M305 now, and don't recall having to use much to set it on zero. Having said that, I find the PST has a more difficult windage knob to read and a lot easier to get lost in how much total input has been added.
The MDT chassis has loads of room between it and the chassis and I haven't removed it from the chassis since I first installed it over 100 rounds ago. I'm having a hard time suspecting the scope as I saw all of two complains on the razor when I was doing my homework before purchasing. Everything else seemed to work as advertised too, and the tracking seemed repeatable (didn't do a formal track test but with all the turret moving I did yesterday, seemed to always return to where I needed it).
I'd yank off the current rings,throw XTR Signatures aboard,mechanically center windage and dump the remainder into inclination.
Nothing to it.
Trying to avoid dropping more money into this thing at the moment. The scope took majority of my fun money for the next while.
This maybe a stupid observation on my part, but you do know to zero the scope you keep the main turret on 0 and move the internal turret to adjust zero. The reason I ask is because I see in the pic that you have the main turret on 3.8 mils. I guess you can move the main turret to see where zero needs to be then set it back to zero and then move the internal turret accordingly. Is that your method to set zero? If so you are missing one of the features of the Razor Gen 2 in that you can zero the scope anywhere/exactly where it needs to be and aren't limited to .10mils clicks.
Yes, I am aware of the zero method method. I had forgotten my tool at the other firing bay, so I just used my turrets to zero and then set the internal zero once I got back to the other bay. Didn't touch my windage for most of the day as I was a little bothered by the 3.8 mils and was dwelling on it, but it is set now. As a side note, the method they use is super easy, and quite fast. Much better than the CRS shim system from the first gen PST.
As soon as I saw it was a Savage I had a pretty good bet on what is causing your issue. Savage is notorious for not drilling the scope rail mounting holes properly on their actions. This is not the first time I have heard about this happening with a Savage rifle....It happens all the time..If you didn't have a quality scope like the Vortex Razor with a good amount of internal adjustment you might not be able to zero it at all...Ray
I have read reports of that before, and there were a couple reports when the rifle was first released a few years ago. Problem is, it isn't a new rifle and I don't recall ever needing this much windage adjustment to pull it to the center.
At this point, I'm thinking either the receiver/rail or the rings are the suspects. Would taking a straight edge like a ruler or tape measure and placing it flush along the rail work for showing any offset from being missdrilled?
