windage not centered after bore sighting ?

[huntandjeep]

I took the scope off my .17 HMR and replaced it with a Burris Fulfield II I took off another rifle and a new set of rings. The Burris (while on the previous rifle) and previous scope on the .17 were almost in the center of the windage travel after sighting in. Now with the Burris on the .17 I'm almost maxed out to the right in windage before actually sighting it in. What's wrong?

[tbotts]

I would try a new set of rings first.  Or just use the rings that were on the .17 with the first scope and use them with the burris.

.  I tried the old rings but they won't allow the objective to clear the barrel with the Burris.

Bore sighting only gets you "on the paper" at 25 yards.  Actual shooting is the best test.  I had to shim the scope I put on my 10-22 build when I ran out of elevation adjustment, and it still shot 18' low at 100 yds.

   If your 10-22 is shooting 18 feet low at 100yds,you better have a gunsmith do your scope mounting for you!

.  I realize bore sighting only gets ya on paper. But of all the rifles I've bore sighted they have all been  close to the center of there adjustments not maxed out one way.  I have had to shim a scope once because at 25 yards I was 8" low with no more up adjustment. Found out later that Hammers used the wrong bases and that was the last time somebody else set up my rifles. How would one go about shimming for windage anyways ?

What rings are you using?

[FC]

I don't think you can shim for windage realistically. I would have a look at your ring/base mounting and make sure nothing is amiss first.

[huntandjeep]

What rings are you using?

.  UTG tacticals. Kinda cheapies but they were getting good reviews on Sniperhide so I thought I'd give them a try.   
 I pulled everything apart a little while ago and swapped them end for end ( front to back and back to front) lapped them and still the same thing? I know the picitinny rail on the rifle is good  because with the cheap Weaver picitinney rings that were on it before, after mounting it only took 6-7 clicks to get bore sighted.

What bore sighter are you using?

What bore sighter are you using?

.   My laser doesn't fit in the barrel of the .17 so I have the gun in my lead sled and am sighting down the barrel and  centering  the neighbors car trailer hub in the barrel. The trailer is 96 yards away. Same way I bore sighted the last scope on this rifle and it worked.

[Heredoggydoggy]

Some Burris rings have inserts you can get to offset a scope.  I used electrical tape to raise the back of my scope enough to get the scope in range.  I think it took a couple of layers of the tape.  It's pretty thin stuff.  you can shim for windage--it doesn't take much.  According to the guy who boresighted it, it was right on.  Actual shooting showed it wasn't.

If you need to you can buy windage adjustable base, Leupold builds some, others do too I bet.

Warne builds them too, and they are good for rimfires.  had a set on my CZ .204, and it wouldn't hit the same place on the target twice.  Got a set of CZ rings (they are a proprietary mounting system, and the ones Burris made were half the price of the CZ rings, and just as good.) and it solved the problem.

.  For a picittiny rail ?

I like 1-piece scope bases, especially for a picatinny rail.  Never had a problem with those.  Did you check the scope tube for damage from overtightening the rings?  That happens occasionally.

.  There's no marks on the scope at all. Going to grab a new set of rings tomorrow and see what happens.

[Heredoggydoggy]

That can be the only problem.  I've used the "sight through the bore and adjust the scope to match" method myself, and it works great!  Make sure you center the windage adjustment on the scope before you mount it, and it shouldn't take much fine tuning to bring it in... 

[BOWHUNTER45]

I have seen a few scopes that are backwards from what they tell you to do ...If you are hitting to the left then try turning it to the right ...it happens ...if someone had the scope before you or someone played with it they could have turned it so many times that you may have to keep turning it until you find the original zero ...usually takes a lot of wasted bullets ...

[oddjob]

   On some scopes you can actually turn adjustments too far and something breaks inside where it won't adjust all the way back.Theres referances to that problem at Pyramid Airguns

[huntandjeep]

Swapped out the rings today and same thing. So going to throw the old scope back on to verify its the Burris.

[Heredoggydoggy]

You probably already know this, but the windage knob doesn't tell you which way the crosshair goes, it dictates which way the point of impact of the bullet goes.  It can be confusing even when you know it! 

[couesbitten]

If I'm taking a scope from one rifle and mounting it on another rifle, I will find "zero" in the scope before mounting and bore sighting by turning the windage and elevation dials to one stop and then counting the number of clicks to the other stop and then putting it half way between the two. This isthe only way I am aware of to get a scope back to a neutral starting point. Don't know if you did this prior to mounting the Burris, but if you didn't, this may be your problem, when you started the process, you were already working with a fraction of your original adjustment range.

   That's what I did with the scope on my 10-22 build.  I got it within 3 inches of zero, then with the elevation range zeroed I was able to fine-tune it from there...

.    This is exactly how I did it. The Burris has 185 clicks stop to stop, counted back 92 from left stop then mounted scope. After mounted I had to move 75 clicks to the right to get it bore sighted at 96 yards. Going to mount up the old scope tonight and try it , if its good than I guess I'm buying another scope.

[huntandjeep]

Looks like the Burris didn't like riding on 2 7mm's. Threw the old Cabelas tactical back on the .17 and after finding the center or the turrets it took 9 clicks to get it bore sighted. Guess I'm buying another Vortex.

Many Burris scopes have a lifetime warranty.  Send it back, and if they repair or replace it, you have a scope to sell if you are still anti-Burris!

that was my thought going to get ahold of them in the morning. Its not that I'm anti Burris I still have 4. Just thinking a Vortex cause I have 3 now and really like them and the warranty.

There's a good deal on a vortex in the classifieds
