Maybe you can offer advice.

My sako 75 was shooting 3-4" low and 3-4" to the left @ 25 yards (about 16 MOA @ 100 yards). It had this exact same POI w/ 2 different scopes set to zero on their adjustments. both scope were mounted in the same sako optilock rings whcih are too high for a 42mm scope.

Do you think it is a barrel/receiver misalignment, bad

dovetails, or a mount problem and should I try some different mounts??



My tikka was shooting bullseyes at 25 yards when i put it in the optilocks with 1 of these same scopes set to zero. I know scopes shoot to a different POI on different guns but the sako seems to far off to be normal!



Its either the mounts or the gun, which i fear some structural problem.



I called beretta and talked with a tech, he told me to send back my mounts/rings to him, he wouild send me some new ones to try out for free. If that doesnt work, I might be shipping her to them for 6-8 weeks!

I'm wondering whether you are expecting too much? I don't know what other people experience, but even at 16" off at a 100, you should still easily be within the adjustment range of your scope. Maybe I'm just easy to please, but as long as I don't get anywhere near the limit of the adjustment range of the scope, I shoot the thing and am happy. Others may have a different view?

There could be several things that are "wrong". Not quite sure what you are expecting. People pay a lot of money to get things put togethor straight as far as rifles are concerned and I would hazard a guess that 80% of shooters have similar situations with there rifles. Some much worse.

appreciate the input, maybe I was expecting too much but have never been this far off @ 25 yards with scope boresighted and set to zero before. It happened with 2 scopes, both at 0, hitting the exact same POI. maybe I am expecting too much??

I think I may be confused as to what you are actually saying or asking. Was the scope mounted on the rifle and then boresighted or was the scope mounted on the rifle at the center of its adjustments and assumed that it would be zeroed?

I'm on your side. That's 64 clicks at 100yds and the further from zero your scope is, the more distortion you'll have. You could use leopold bases and make your gross adjustments with the bases.

From what you've told us, I would say the problem is with the receiver. The dovetails are not aligned with the barrel threads. I would have expected better from Sako. Of course I have seen Rugers much further out of alignment than that!

Turn one ring 180 degrees. If the front ring is dovetailed do that one first. If no POI windage shift rotate the other ring(if possible). The idea is to determine if rings are machined true.

Shim the rear ring saddle for elevation.

I mounted 2 different scopes in the same scope rings/mounts on the same sako. Both scopes were set to zero. Both scopes shot at the exact same POI @ 25 yards, which was 2.5"-3" low and 2.5" left. I guess it wasnt as far off as I thought but it still seems like something isnt lined up somewhere!

I have encountered similar problems on a number of rifles I own. Rings either not true or in most cases it was the mount holes not being centered. I encountered this on a Winchester, Browning, Remington, and recently a Weatherby. All required use of the Burris Signature rings with there Posi-Line inserts to correct missalignment. I prefer dual dove tail mounts so no adjustment is possible with the bases. I have one rifle that was tapped post production, an old Sav Mod 99, that was so bad that I had to use Redfield style bases with the windage screws and a 20" corrective insert in both the front and rear rings just to be able to use the scopes internal adjustment. Can't blame that one on the factory though.

Of course I have other issues with the Weatherby also. It lives up to its accuracy guarantee of 1.5 inches at 1yards with factory ammo and that is about it. Lots of tweeking yet to do.
