Scope Elevation Issues

[nmkid]

The rifle is a REM 721 with a new REMAGE barrel from NSS. in 25-06. The only thing that was changed during the build was the barrel. The scope is a Nightforce SHV with a 20 MOA base. Torque settings on the entire rifle double-checked this morning. At 100 yards, I run out of adjustment and was still hitting almost 15" high. I also re-centered the crosshairs. I ended up putting up a 3'x3' piece of paper at 100 yds. and got a nifty .354 3-shot group...14.5" high! What am I missing? HELP! Oops on the title misspelling.

Did you remove scope base? Mounted backwards?

 

[CJ6]

Get a set of Burris Signature Zee rings.

Yes. Nope.

Most likely not, but since it was just the barrel replaced, perhaps there's a spot where the barrel is touching in the forend and in conjunction with the torqueing down of the action screws might be forcing an elevated point of impact? Just a tought.

No. The barrel and the barrel nut are completely floating. I put a laser sight on it, and the same problem. I am just completely out of ideas. Other than ordering a 0 MOA base. I don't think it has anything to do with the barrel, as it did shoot a very nice 3-shot group.

If you hit nearly the same place after “recentering” the crosshairs and also at the bottom of the turret, because it won’t go down enough, then the elevation knob isn’t moving crosshairs.

Is the eyepiece clearing the back of the base? If you crimped it down on the base, you would essentially have a steeper declined cant and would never be able to “lower” the turret enough to center up.

Or,

There is a tiny recessed screw(s) on knobs and maybe they are loose. But when they are, the adjustments feel muddy.

Or,

Nothing is actually moving inside, which you can test by holding the rifle perfectly steady and clicking the scope turrets to see if the crosshairs move appropriately on the background.

Or,

If you are using a pic rail, the rear crossbar never did seat fully and the scope is pointer down too steeply as a result.

It’s not the new barrel. It’s also not the base alignment because one, you are high not right or left and two, it worked before. But some round actions might let you put it on backwards, although you checked that.

The crosshairs are moving. I "walked" the impact done about 15" or so until I ran out of clicks. Every time I adjusted the crosshairs lower, the impact changed accordingly. I held the rifle on the shooting rest while another range member turned the turrets, and I could see the crosshairs moving. Also, yes, on clearing the base with the eyepiece. The scope adjusts perfectly until I run out of adjustment. I would gain some more "down" adjustment if I went with a 0 MOA base. Right? I think I will remove the scope from the base and attach it again. I'm lost.

Edit: It’s not. I reread your OP. But that one is in the wild somewhere.
—-
It’s not the barrel, —- unless you bought the one and only barrel off the swap meet estate table at Ben Avery, — that I saw with my eye was drilled off center, and Larry B concurred. The decedent never cut that blank, and it was a very good price.

Is it “that” barrel?

 

[davidjoe]

… You don’t have scope inadvertently turned 90 degrees, right?

No, it is a brand new barrel from Northland Shooters Supply.

In all honesty...Not this time! LOL.

 

[davidjoe]

Well, if another scope on it does the same thing, then that does rule out this scope.

A 20 moa base should honestly be no problem at all. 30+ and some scopes, yes.

 

[steve210]

If nothing but the barrel was changed, it seems logical to me that it's the barrel. Something is crooked would be my guess.

 

[Coyotefurharvester]

Did you change the lug?

 

[Lone Hunter]

I have ran into the same problem as you. I have and have had 20 moa bases on my rifles. The barrels are from NSS also. Not knocking NSS Either.. All my barrels shoot great. I have taken the 20 moa base off and put on 0 moa bases and used Burris XTR Signature Rings. What I ended up doing was putting the inserts in the bottom and not tightening the rings down and change inserts holding the scope down until I could get it on paper at 100 yds. If I remember correctly I was 6-8 moa high at 100 until I did this. I am near the bottom of my turrets at 100 so I have most of my elevation left in the scope plus whatever the insert is. I use NF 12-42, NF 5.5-22, Sightron SIII 10-50 like this and don’t have any problems.
Edit: this is also Remage barrels
These are the rings I’m talking about

It happens. I had a new barrel fitted by the maker and fixed it easily by shimming the mount. Or, as suggested, Burris rings. It's likely just the barrel orientation. Probably shoots fine.

some people do clock their barrels when chambering shouldered barrels. this is measuring and marking the muzzle end when its in the lathe. how much differance was the original barrel? did you change the recoil lug? i had an NF once that my windage adjustment all of sudden started shooting 20moa off.

 

[rocketron]

Does the scope have zero stop?

A much heavier barrel and a new, thicker recoil lug was used.
