Out of windage adjustment.

[Arcaporale]

Almost a year ago I purchased a Savage 10 FCP, a TPS 0 MOA rail, a Vortex Viper PST 4-16 SFP and some Burris xtreme tactical rings. I mounted it all my self and had no issue at all sighting it in and getting the scope zeroed. I did notice however when it was zeroed (@100yds) I only had another 12-13 MOA of windage adjustment left which didn't really concern me at the time.

Recently I purchased an EGW 20 MOA rail as I needed more elevation adjustment. I remounted everything and re-zeroed my scope. However, I am finding now that my zero leaves me literally with only 2 clicks left adjustment now, or 1/2 MOA.

Now I am concerned. I did a quick Google search and found other people with similar issues and many things were suggested to them including adjustable rings/bases, shims etc.

I plan on re-mounting everything tonight and re-positioning the rings where the front will go to the back and the back will go to the font. Not sure what if any affect this may have but figured it may be worth a shot.

I don't want to use any of those adjustable rings or bases and I want to troubleshoot this as much as I can before I end up having to send my gun or scope back in.

What suggestions or input do any of you have to help me solve/troubleshoot this issue?

their is a lot more to mounting a scope then just bolting it on!!

Do you have any "tools" for mounting scopes?

Alignment bars

Lapping bar's

Level's

Laser bore sighting equipment

The list goes on and on!

It might be worth you having some one do it for you so you are sure it's done right.

If the scope windage need to be adjusted more then a couple clicks L or R from center the scope is on wrong.

Have you shot the gun at shorter or longer distances? If not try this first.

Shoot it at 25yds and 200yds if you can. If the gun's point of impact moves L or R the problem is "not" the scope.

From their check to make sure the

1 - Mount is parallel to barrel

2 - Rings are parallel to mount

3 - Rings are parallel to each other

If you are in the Bay Area PM me

I do realize there a bit more than bolting it on, yes and I'll admit I'm a little too cheap for lapping bars and mounting bars and laser bore sighting equipment.

The rifle shoots great and holds a zero just fine, I can normally produce 1/2 MOA 5 shot groups on a regular basis with the gun. I was shooting it 800 yds last weekend and it shot great.

I spent some time last night playing with the setup. Here's what I did:

1. Setup my rifle on a table with my bipod deployed and leveled the action.

2. Then I shined a flashlight down the bore in a dark room and marked the spot that was produced on the wall with some tape.

3. Then I shined the light through the ocular on my scope and it produced a blurry silhouette of my reticle on the wall. While holding the light through the scope I moved my turrets around and watched the reticle track across the wall. When zeroed the reticle hovered over inline with the tape on the wall, but as I said I only had 1/2 MOA adjustment left.

Looking through the scope at 4 power I was able to confirm the reticle was in line with the spot marked on the wall.

4. It took off the scope and mounted another one on the rail that I have for my AR. I repeated step 3 and I was able to center the reticle on the spot and still have plenty of tracking in both directions.

5. I then grabbed my rings and torqued them down to the rail to 65 in lbs, laid my scope on the rings and did the flashlight bore sighting deal again. This time I switched the rings around and played with different locations where the rings would mount to the rail and the scope mounts to the rings.

6. I was finally able to get the scope to stay centered on the spot on the wall while having plenty of MOA of tracking in either driection. I torqued the rings down to spec making sure the top and bottom of the rings were evenly gapped on both sides.


I know how stupid this all sounds but I've used this method to bore sight rifles in the past and it's always gotten me on paper @ 100 yds.

In conclusion I realize that my rings are probably not all that great and need to get lapped or replaced.

The new base is the problem.

[Vu 308]

Base, or rings tweaking due to the 65inch pounds of torque. Burris Tac rings are not exactly the quality I look for in a precision setup.

If you are on a budget, give Mike Cecil with CS Tactical a call, he may have some rings people traded in for a deal. Badger, Nightforce, Seekins are the only hardware I trust on any of my rigs.

What did you torque the top of your scope rings to?

Another possibility is the holes in the action are off. I had that problem on a bone stock M700LA.

I was able to bore sight using the above method with another scope with no problem on the same base but different rings and scope so I don't think it's the base.

Also I measured the holes on the base to the edge of the base with some calipers yesterday, the holes seem pretty well centered. Again don't think it's the base.

Top screws on rings were torqued to 25 in/lbs, I torqued them down sequentially in a zig zag pattern taking care to make sure that there was an even gap at both sides between the top and bottom ends of both rings.

Like I said I was able to bore sight it with plenty of windage at both ends last night, but I think the rings are just cheap.

I'm not really on a budget but at the same time I don't want to drop 100-200+ on some new rings if I can make this work. Think it's worth a shot getting a lapping bar?

If I do get new rings, the Vortex ones seem to have good reviews and I know they produce a good product for the money, anyone have any experience with the Vortex rings?

I will go to the range this weekend and zero her @ 100 yds and see how much windage I'm left with.

Maybe the rings aren't centered on the rail.

Vortex rings are made by Seekins or Badger, depending on what model you get.

I have one set that is Badger, and one set that is Seekins that came with my Vortex Razors

Great thanks for the info. I will zero my rifle this weekend and see if it works out. If not I will buy the vortex precision matched rings.

Wanted to provide an update and a warning to anyone considering the Burris extreme tactical rings.

Ok I broke down and bought the Vortex rings, and am I glad I did!

While removing the Burris rings I could see upon further inspection that mine were indeed faulty, the recoil lug on one of the rings was not squared up with the rest of the base of the ring. The recoil lug which also is the screw to clamp the ring to the base was not straight at all. So one ring was raised a little higher than the other and canted to one side. Not enough to see with the eye, but more than enough to really screw things up for me.

Most reviews I've seen on these rings were pretty good. I just got a bum set. But it goes to show you get what you pay for!!
