Well I got my scope and base for my 10FP recently. The problem is that I can visibly see that the scope is not alligned with the barrel. I've tried reseating the base and scope a million times and it seems that the base may have been machined improperly.


Any thoughts on this?


Setup:
Savage 10FP
DNZ Game Reaper 1-piece base and rings
Burris Fulfield 2
 
New scope and new mount?? How are you checking alinement,Pull bolt ,look through barrel and site? New scope should be centerd more or less from factory but you could run it to the limits and then recenter by click count and then see how much off. Also run a straight edge up the barrel centerline and over the drilled holes to get a loose check on the holes in your action. Might be better to go to tally if a nice looking unit is wanted or maybe pull out and old site of Weavers to try.
 
I have tried removing the bolt and pointing at an object and the scope is definitely off. I know it can be adjusted slightly but I can visibly see that the scope is not centered and it pointing to the left. If I can see it just by looking at it, it has got to be really bad.

I'm going to bring the gun to the store and see if they will let me "borrow" another set of rings and a base for a minute to compare against mine. I wouldn't be suprised if this "Game Reaper" base/ring assembly is off from the factory. The build quality seems to be very good (machined billet?) but the price was pretty low on it.

If it turns out to be the mounting holes on the Savage itself well then I don't know what I am going to do. That would be really appauling for a manufacturer to not have the holes drilled squarely from the factory, especially on something like a 10FP that's supposed to be a good target rifle.
 
Maybe you can get it right with just a mount change. The dnz is a nice look'n mount. If the gun is the problem call savage and get a return order and see how they want you to ship it back. It would seem odd for it to be the holes in action are off but as many guns as manufactors are putting out today quality has slipped a bit at times .Look at all the s&w returns we read about now adays . Couple years ago returns were more whin'n than substance.
 
Good point. I believe this rifle was manufactuered during the rush. It would make sense if quality slipped a touch.

I didn't know that SW was having problems too. All of my Smiths have been absolutely flawless but they are a few years old.
 
Is the scope body/tube pointing in a different direction than the barrel, or are the crosshairs pointing way off?

If you can tell the body of the scope is pointing way off then that's bad...
Could be the scope base or the mounting holes in the reciever.

If the crosshairs are way off but you cannot tell if the scope body is misaligned then that could have an easy explination. Sometimes scopes sent from the factory are adjusted way to one side.

If it's the crosshairs, then try this:
-Turn the windage adjustment all the way to one side.
-Turn the windage all the way to the other side, but count the number of clicks or note the number of turns it takes to get to the other side.
-Once you know the number of clicks/turns, then adjust the windage back in the other direction but only turn the adjustment half of the number of clicks/turns. That should give you close to the mechanical center for windage.
-Next step is to do the same thing with the elevation.
-After that, stick it back in the base and check to see if the crosshairs are pointing close the same direction of the bore.
 
I don't see how it'd be possible to mount the base if the Savage action holes were off. The Savage has a round receiver front AND back and the underside of the DNZ base is precisely machined . There's no front/back (yaw I guess you could call it) adjustment of the base relative to the receiver. The base as a unit can rotate around the receiver but that's it. If the holes were off, you wouldn't be able to get all four screws started, or if you could, it'd be obvious that the base wasn't sitting flush on the receiver.

Get a long 1" wooden dowel, a straight one. Or a 1" nylon rod, or steel, aluminum, etc. One as long as the entire rifle. Set it in the rings and hand tighten them. Set the rifle in a rest. That would be about the best visual indication.

If it's off, make sure you you take a photo. My speculation would be the rings are not true with the base. With a straight plane to look at, your eyes aren't fooled as easily.

If that's the case, go here

If you managed to mount the DNZ to the receiver without any issues then I'd agree with DRYHUMOR. However, I'd contact DNZ first. It's not a Chinese knock-off of DNZ is it? Either way, I'm sure DNZ would be interested in helping you out.

:)
 
I appreciate the advice guys. You have some great tips and tricks here!


The thing is that the DNZ game reaper is a "one piece" unit that is a base and rings combo.


Yes the BODY of the scope is visually not true. My brother and I can both easily see this by visual inspection which is why I don't think I would even both trying to use the fine adjustments for the crosshairs. The scope is perfectly straight (can rotate it in the rings without any variations at the ends of the scope).


It is an authernitc DNZ according to MidwayUSA

We all know what a DNZ is :) ... but the ring part of the mount could be out of alignment (tweaked, twisted, bent) relative to the base part of the mount. What we're saying is, if the DNZ was easily mounted to the receiver with no obvious issues, then it's highly likely that the rings are twisted relative to the base. The fact that your scope is able to rotate freely as well as move forwards and backwards seems that both rings are aligned with each other, just not with the base (DNZ is one-piece we know). If that's the case, something went wrong in production so I'd still contact DNZ and see what they have to say.

:)
 
The DNZ mounted to the 10FP perfectly.


I think your right- they very well may have machined the rings cock eyed. They appear to be parallel with each other, but not with the base geometry.
 
Is this a new gun as well? Sounds like the holes may not be drilled and tapped correctly. That used to be fairly common. That is why the windage adjustable Leupold rings and bases were made. To correct for improperly drilled holes.

If this is true changing to that type of mount is the easiest fix. Or sending the rifle back. I suppose it is possible the barrel or reciever may not be threaded straight as well. Bought a Ruger Blackhawk that came from the factory that way once.
 
It is possible it is the Savage so i am going to try to borrow another base just to confirm that the savage is or is not the culprit.

The DNZ appears to be absolutely exquisite in the build quality but that doesn't mean that it can't be a dud.

I contacted DNZ late lastnight and they have already replied to me and offered advice and if need be, replacement. Very good customer service!

Well before I start shipping items around DNZ reccomended swapping the rings around (front to back). Apparently they are interchangeable from a mounting perspective (only difference is the side of the base on it.
 
After following DNZs reccommendation of rotating the base/ring assy 180 degrees I have found that the scope is still visibly pointing to the left. This means that it is not the base and scope but rather the rifle itself.


I think this will be the absolute last Savage rifle I will buy. What kind of quality control can they have if they are sending out their higher-end rifles with a barrel not aligned to the reciever? One would think that they would have some sort of a test in-house where they put the rifle on a jig and check to see that the barrel, mounting holes, reciever, etc is all in alignment before shipment.

I also don't think it is possible that this rifle could have been damaged in shipping as their are no signs of abuse.

Uh ... no it doesn't. I still don't believe that you could easily start and tighten all four base mounting screws if the tapped holes were off. On a two-piece base it wouldn't be a problem. I'm still betting that the mount is off rather than the receiver but with measurements I'm just guessing.

This is what I'd do ... remove the DNZ mount, start all four screws in the receiver holes (just one or two threads), put a 12" straight edge (ruler) up against all four screw threads (they should line up), and draw a line with a fine felt tip pen or permanent marker over the barrel nut and onto (along) the barrel as far as you can. You'll soon see if the screw holes are off relative to the centerline of the barrel. Post a photo of the results if you have access to a digital camera.

Sure it does. I don't think it is the actual screws that are off. It think it is the reciever to barrel connection.

If it was the base/rings- rotating the assy 180 degress should invert the issue and make the scope point to the right.


Oh and just a little bit more fun. Savage says it will take 3 weeks for them to fix the issue. Top notch service for a DOA rifle.

Start by assuming that all four tapped holes in the receiver line up with the centerline of the barrel. Also assume that the rings on the DNZ mount have somehow been machined off axis so that the scope tube isn't aligned with the screws on the base. The drawing on the left shows the scope pointing to the left of the centerline of the rifle (assuming that the barrel is pointing up). The screw holes are shown in the mount for reference purposes only. If you remove the base without removing the scope, rotate the base 180° and reinstall all four screws, the drawing on the right shows the position of the scope tube relative to the centerline of the barrel after rotation. The scope is STILL pointing to the left of the centerline of the barrel. So what has rotating the base confirmed?

Wow I really feel like an idiot now. Complete brain fart there and your absolutely right. I will do the ruler checkup thing before I send the Savage in.

The only thing is that even without the scope mounted to the rifle, towards the front part of the stock you can see that the gap between the barrel and stock is smaller on the right side of the gun vs the left. Seems a bit odd and again makes me suspicious that the barrel to reciever alignment is a little bit off.
 
I had a similar experience with a picatinny rail on a Savage. The thing was so far out of whack I could not zero the gun using all of the windage available in the scope. I had no idea what was wrong and was going nutz. A friend of mine let me use a rail he had and his scope to test the components and identify the problem. Using a different rail and a different scope did not fix the problem. It turned out that the holes in the receiver were slightly off. Looking at the receiver by itself, it was impossible to detect. A few thousands of an inch will throw it way out of kilt and you will never see it by eye-balling it. I sent the gun back to Savage and they installed a brand new receiver. Savage is a great company that makes the best firearms for the money today.

That's not uncommon. You'll find somewhat poor stock fit in all but the highest end guns.
 
Only thing is that my cheap Mossberg Plinkster doesn't even have this offset on the barrel to stock. My Ruger and my Marlins also don't have this.

Not a big deal to me as long as the barrel/reciever is aligned but we will see. I haven't had a chance to look at it yet.
