Rifle Scopes Large amount of windage to zero.....

[AussieH]

Hi Guys,

First up great sight I stalk it a lot and have learned a lot.

Now my problem, I am setting up a new rifle and when I went to zero it from factory (100M) I had to dial 5mils of elevation (not worried about that) and over 5 mils of windage to the right...... After I slipped the scales and returned the knobs to zero the elevation was fine but I now only have 2.5 mils of travel to the right before it bottoms out, out of 5 (left is fine). Is this normal or could there be something seriously wrong here?

Rifle:
Remington sps-v
AX AICS stock
Badger Ordnance 20MOA base
Spuhr ISMS zero cant
Steiner 3-12x50 Military

It shoot straight so far (only been to 300M) nothing is loose, I have taken the scope of a couple off a couple of times and made sure it was on straight made no difference to anything.

You're stuck with how Remington drilled and tapped the receiver. I've seen a few worse than that.

You could have a rifle plummer true it up and re-tap for 8X40 fasteners.....just a thought.

^^^What he said. There have been worse. Have it retapped 8-40 by a reputable smith, to str8n it up.

Ah ok thanks a lot for that guys think I will take your advice and get it re-tapped appreciated the quick replies

is shimming an option? or just a bad idea?

Your base is not aligned with the bore.
Need new base holes to align with the bore of the rifle.
Needs a smith with the proper tooling to bring the bore line to the center line of the base.
Sounds trivial but its not.

So in this case what happens to the old holes?

They become....assimilated.

check to make sure when you tightened down your windage knob after you re-zeroed you didn't push the windage cap all the way flush to the scope housing. The steiners have an interesting windage knob set up that you can bottom out on the turret cap before you actually reach the full windage available in the scope if you don't place the windage turret in the proper spot when you tighten your set screws. I'm not certain but Your scope should have more than 5 total mils of windage. If you do, you should have 5 mils left and right after you properly set up your zero because of the built in windage stops.

I would loosen the windage cap slightly, and it should pop out a little bit. Push it back in just until you can see the reference line for zero then tighten down your set screws.

You should have your full 5 mils right and left for windage.

you have mis aligned mounting hole issue as noted above.
It's not uncommon for factory rifles to them drilled off center unfortunately.

Tried playing around with the windage knob it doesn't bottom out so to speak it gets to about 2.6 and gets tighter like its out of travel add the 2.6 to the over 5 mils I have already adjusted to zero and that's 8 mils travel to the right looks like it might be a trip to the gunsmith one day

You're not alone... But a good reputable smith can fix the issue since the holes are not already opened up.

USO has windage adjustable rings for mis-aligned bases. I have a set of these that came with my scope package in 34mm x 1.2"H sitting on the shelf with 100 rounds under them. I did't need them on my GAP so I replaced them with Badgers. If your base is not drilled parallel to the bore then something like this would save you trip to the smith.

I have a Hollands base designed to fix the problem.
