What am I overlooking?

I purchased a Bergara B14R a couple months ago and finally took it out yesterday.
Mounted a Zeiss Conquest scope and very excited to sight this bad boy in.
Got it on paper on my first shot so started dialing her in.........could not move it over far enough to the left as ran out of windage adjustment.
This scope was just removed from another rimfire rifle so know the scope was not the problem
I had installed a used Nightforce scope rail and new Burris Zee rings so went home to change those two items to see if that would make a change........exact same issue.
My first conclusion are the holes are not drilled parallel with the barrel or am I missing something more obvious.
Look forward to any other ideas on what the problem may be?
Thanks

did you bore sight it? take the bolt out ,mount it in a rest or padded vice in the shop and aim the bore at a target or what ever ever on the far wall, than see what the scope adjusts do, if you can center the scope to the bore, it should work, elevation will be off a bit, windage , should be close.
I would center the cross hairs in the scope and see where it looks in relationship to looking though the bore. If it is way off, mounts are the problem, or rings.
 
Does the scope have target turrets? If so, remove the windage turret and see if there is a limiter peg that is preventing the adjustment from moving any farther.

Hi Marshal, that is the exact method I use as I do not have a bore sighter. Find this method always gets me on paper to begin with so have never had a desire to purchase a bore sighter. This is the first time I've had this problem but with age I often miss something that is very obvious to others.
I counted how many MOA of windage my scope has in total (19) and moved the windage to the middle. The scope was off ~6 inches from centre - watched the crosshairs shift over while moving turret so scope appears to be functioning as it should. I was ~2 inches away from centre when windage turret bottomed out.
I have sent a message to the seller to see if this has been a problem with other Bergara owners so will see what he has to say.
Thanks for the reply......greatly appreciated.

Are those the burris rings with the inserts?

Switch the rings front to back?

Yes, they are.......I did give the back one a 180 degree turn hoping that may be the problem but that did not change anything.
That is when I changed out the complete set to see if any change......none.

Yes, it has the target turrets but pretty confident this model does not have that option but will check to make sure - thanks for the suggestion.
 
A simple test?
Pull the bases.
Install the forward and rear base screws.
Use a yard stick and lay it flat up against the two screws and see
iff'in the edge of the yardstick is parallel to the bawrill?
 
Interesting. What does the scope rail look like? I'd be carefully examining and measuing the layout of its mounting. You could try to use a straight edge to see if it's in line with the bore.

How far out are we talking? You said it's on paper, I assume @ 25 yards?

Love that idea.......will check that next. Thanks!

When I went out to shoot/get it on paper.......was @ 50 yards.
Looking through barrel at home was @ 15 yards.
 
Here are the fruits of my efforts.
Tried a couple different methods as wanted to see if consistent results.
The red mark at the end of the barrel is the centre line of the bore.
Pics tell the tale :cool:

Not certain that I know how, but I would now be wondering if the barrel is installed "straight" with the bolt's bore in the receiver? If both mount holes or that rail are truly "top dead centre", then the holes would be correctly placed?

That is certainly a paradigm shift - I could actually see that as a higher probability than the holes being drilled incorrectly.
Will get a hold of Bergara and see what they have to say about this problem.
Thanks for your input as opened up a completely new thought process to the problem.
The power of brainstorming once again proves beneficial........thanks to all that gave their input - greatly appreciated!!
 
Was just looking at my Foster Universal sight drilling jig - seems to be assuming that the barrel will have it's bore in dead centre of barrel, and I have barrels here in which that are clearly not the case. That sight jig is going to place the scope base mount holes dead centre on the exterior of the barrel. So the alignment to figure out, is the alignment of the bore line in the barrel (not necessarily the outside of the barrel) to the "theory" true centreline of the receiver, which is often the bolt bore. Then the scope mount holes need to be very close to TDC above the centre of that bolt bore line. I think. I do not know if such a thing exists, but a polished rod about 12" to 16" long, that smoothly and snugly fits to the bore size of the rifling, would provide a reference inside the action to measure to the bolt bore? Not something I have ever done - usually is "bad" enough to see, just looking into the breech end to "bore sight".
 
I also have several "gunsmithing" books that mention barrel straightening - is apparently done at Anchutz barrels, and one book had a picture of a rig in action at a Remington factory. The old school "trick" was to see a crooked shadow line, cast down the barrel by a string or rod hanging vertically in a window - the "line" in the bore showed straight or crooked and where. Maybe that can be extended back into the receiver bolt bore - I do not know. But I do know there are machinists / gunmakers / barrel makers that can measure what "straight" is, and to measure the alignment between two bores - but I do not know how that is done.

Call Odell engineering great people
 
It can be very difficult to tell whether the holes or barrel are not as they should be by lining up the holes and projecting no more than 24" to the end of the barrel. That's probably too short a distance to tell for sure one way or the other. For a more certain evaluation it would be necessary to be able to assess how far off it would be at the distance being shot (or at which the scope ran out of windage). In any case it's likely there are more reports of holes not being centered than barrels being installed out of whack.

This is a brand new rifle so I am hoping it will be a warranty claim.
I purchased from Wolverine Supply so I suspect they will take care of that end of it.......with the Covid19 they are hard to get a hold of as sounds like their shop is presently closed??
Left an email and voice mail so hopping to hear from them soon.
