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?

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.

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.

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 ?
