Scope mount issue, shoots too high...

[McCrackin]

Mounted a Nightforce NXS 5.5-22 x 56 (bought from buddy) on an older Kimber 8400 .338 WinMag with Talley one piece mounts.
Sighting in today, with the Zero-stop adjusted all the way down, I"m hitting 7" high @ 100yd., 11" high @ 200yd!
What the heck?
I just looked at the Talley websight, they don't sell any +/degree (or whatever you super-long shooters call it when there's cant built into the bases to get "out there") bases for this gun, so I don't think it's that...
Probably call Talley in the am to verify I can't have the wrong bases.
Any idea's from the collective mind?
Thank you in advance...

Bases can be shimmed. Kits available, but can be made from pop can etc.

I hear you on that, may have use a PBR can to make AR barrel shims to clock the nut in the past...
I'm just surprised that two respectable products would create this situation. I've never shimmed a scope in my life...

Been there.

My father in law worked at Bass Pro in the Firearms dept for many years. Every now and then a customer would bring his rifle back in because he was shooting way high and could not turn the scope down. Now the scope was mounted by a Bass Pro employee. When my father in law looked at the scope he found that the other employee put the scope mounts backwards. I have seen Canted 20MOA rails put on backwards.

I think it's the the zero stop . you said you turned the zero stop all the way down , that enables the zero stop . you want to remove the turret cap . loosen the 4 allen screws about 2 full turns . raise the upper zero stop clutch until it's about flush with the center brass bolt . snug the 4 allen screws . put the turret cap back on . sight the gun in . after you're sighted in , then turn the upper zero stop clutch down to make contact .

Zero stop needs reset. Easy.

You are correct, but I've already tried that, twice... That is what has me perplexed!
Who know's, maybe I'm 'fn doing it wrong. I did watch three videos on it to make sure I was remembering the process correctly...

#%**$#@*&*%#...
Just as soon as I'm certain "I did it right", I find I did it wrong!
After loosening the four tiny allen screws, I was turning the top half of the zero-stop clockwise (down) until it hit bottom. I just realized that I needed to turn it counter-clockwise (up) so that I could lock it in place, then I'd have more down travel.
Counter-intuitive always gets me.
Thanks for the help guys, you inspired me to dig into it again!

LOL. You do things the way I do. I am glad you got your problem figured out.

 

[BillLarson]

Well...... at least you got it fixed.... and did`nt have to hire it done...... it aint easy being poor....

 

[Gar Guru]

you right about that not easy being poor!

I had that problem on an AR-15 with fixed carry handle when mounting a scope for load development. I just put a small piece of angled wood under the rear of the carry handle mount and BINGO!

As a side note there is a guy in Washington who can mill the Talley ultralights to give 20 moa elevation. Don't have his name handy but someone at Talley have me his name last year and I had him do a set for me.
