Strange experience shooting new Anschutz 1710 d hb today

I mounted my brand new Bushnell Elite 4200 8x32x40 on it today. I used the Burris Signature Zee rimfire rifle rings. When I went to sight it in, my shots were hitting way low and way to the left of POA. next, I found out there wasn't enough scope adjustment in either direction? first time I ever had that problem with any scope especially, at 25 yards :eek:. I went home and put a Nikon 6x18x40 Buckmaster on went back and was able to get enough adjustment to sight it in properly. Do those particular 4200 models lack in adjustment range normally, or did I receive a faulty scope? Please! don't tell me it could be a problem with the Anschutz barrel not straight in the receiver etc. :eek:
 
I have seen this happen before. When one scope has enough adjustment, and another doesn't, it is usually as simple as that. The reason comes from limited travel of the erector tube. With a 1" scope tube, there is a balance between light gathering ability and adjustment. Increasing the internal lense diameter does increase light gathering, but decrease adjustment. Decreasing the lense diameter would obviously increase adjustment, but limit light gathering. The only thing you can do if the scope isn't faulty (binding erector tube) is to realign the mounts.

Not having the scopes in front of me, I can't speak to that issue but I can say that with the rings that you are using, your are a lot closer to a solution than you would be with other designs. One of the reasons that the Signature Zee rings were introduced was to deal with this kind of problem.

By knowing how far off of the aim point you are, at a known distance, as vertical and horizontal distances from POA, and the center to center spread of the scope rings, one can figure out which offset inserts to use, and in what orientation they should be placed within each ring, to compensate for alignment issues such as you describe. It takes a little measurement, and you should measure your POI's offsets with the scope's reticle centered and the "0" inserts. For example, if your point of impact is 1" to the right at a measured fifty yards, and the center to center distance of the scope rings is 3.5 " we can say that 1"over 1,800" (50 yd.) = x over 3.5". Cross multiplying gives us 3.5 equals 1800 times x, and dividing both sides by 1800 gives x = .0019 or approximately .002 of adjustment at one ring for each 1" at 50 yd. If you need to compensate for both horizontal and vertical misalignment, the inserts' splits can be clocked to give varying degrees of horizontal and vertical compensation, depending on how they are rotated. These calculations are are a little more complicated and involve the use of a little trig. and a scientific calculator.
 
Michael,
If these are the type of rings that have inserts or the back ring is adjustable, take a look at this as a problem. No way that rifle shout be shooting that far off. I am betting it is in the rings.

I just recently had this happen where a 35 year old .300 Weatherby that I was sighting in for the first time, would not allow me to use a 3x-9x 20 year old Redfield "Partner" scope. The rifle was shooting 30" high. Using the sigth-in-through-the-barrel method, I could see the alignment was way off. There was not going to be enough adjustment with any scope I would use, being that in this case the fault was not with the scope..

This is not the first time I used home-made aluminum shims, a lapping bar, and my Kokopelli bars to get a rifle to shoot on the X.
 
I had more than one person on the RFC forum say that the Signature ZEE rings would not fit properly on the Anschutz 54 action because of the rounded dove tail top. So, I will try my BKL 257 High rings and see what happens.
 
My bad. I assumed that your rifle had been drilled and tapped for Weaver bases. After reading your post, I went to the Burris web site, and could not find any reference to Signature Zee rings for rimfire dovetails. They show rimfire rings, but not of that type. Do your rings have plastic inserts?
 
p5200, I have several sets of Burris Signature rings for the dovetail mountig that seem to work OK on 4 different Anschutz. I like the Z-ring setup better, though, so I am changing them all to that for both my rimfires & centerfires. With that setup, I can switch scopes around a lot easier. I tend to put big scopes on for load development, then change them out to more practical scopes for actual use. The z-ring setup is definitely stronger.
 
Fellers,
Signature is the word that tells you the rings have plastic inserts, Zee that they are for a Weaver base. Before they were called Signature, they were called Pos-align.
 
Aren't these the rings that have several types of plastic inserts, so you can adjust them for scope alignment. Like if you need 20 MOA for long range, etc.

Could you let us know if the inserts are all the same ,such as zero degree offset or other combinations of+5,-5 degree, +10,-10 degree or +20,-20 degree offsett.They're marked on the insert outer surface. Usally the rings come with the zero degee inserts. RANDY

What bases do I need to get so I can use the ZEE rings? I have an extra set of them I could try. Thanks!
 
If the bases are solid ,no loose screws. Check to make sure that some of the screws aren't bottomed out.If everything looks tight then whoever drilled the holes my be at fault. I'd ether call the factory, if it came that way, or purchase a offset insert package and install per the directions RANDY

The scope rail just has the four screws in it that can be removed to mount Weaver type bases but, no bases are mounted there yet. I've been searching the net and found that Weaver #91 bases are suppose to work there. May try to find a pair locally tomorrow. Thanks!
 
To correct a few previous pots... the offset inserts are marked in thousandths of an inch. the angle will depend on the spacing of the rings.
 
I ran into the same problem with my 1710 and with 2 different scopes. First was a Swarovski 3x12 50L using Weaver bases and Warne rings; and then an I-Dono-know tip-off generic .22 mount. Both shot down and right. The closest I could get to the bullseye at 25 yards with Max left and max up was 3 inches low and just slightly right of center.


I let things sit for 3 years and decided to try a Leupold VX-R 3x9 50mm. Not surprisingly, it also shot low and right.

Could there be something that the factory did to make this rifle not compatible with 30MM scope tubes?
 
With bkl rings i have never seen one not right on zero at 50 on an annie. I like most silhouette shooters use bkl rings with 11mins of shims in the back and with that setup the cheapest of the cheapo scopes and the highest dollar scopes have no problem from 40-100yds
