Gunsmithing Help with scope mounting?

[johncamino]

Hello,
I have a Remington 700 BDL with a Std Leupold mounts as depicted. I don't know if the base holes were made correctly when Remington made the rifle. I recently had some custom work done by Leupold on the scope and their report indicated that I had 15 MOA of windage when the received the scope. I received it back re-centered, and I decided to use a Leupold zero point to zero the windage. When I went back to the range, I was on paper, but again I had to use 15 MOA of windage to zero-out. I didn't like this, so I placed the Leupold zero-point on my rife, and re-centered the scope windage, and adjusted the windage on the rings until the picture looked the same as when I zeroed on the range. It worked like a champ, and I was able to zero, with 0.5 MOA of windage on my scope at 100 yards. Here is my problem:
I want to install a 20 MOA base Picatinny rail and I'm afraid that there will be no way to take out the windage, and I'll have to again dial in 15 MOA of windage in my scope. Attached are the pictures of my scope and the cross-hair picture through my zero-point with the rifle zeroed at 100 yards with no windage required in the scope. It seems way off, and I'm wondering if a gunsmith could correct this when installing a 20 MOA base, or if I'm just going to have to live with it?

See those 2 screws on the sides of the rear mount ?

Yep, use those to zero windage.

I wish all problems were so simple :|

I did that, and was succesful. The problem is want to use a 20 MOA base, and those two screws won't be there any more.

Unfortunately, with only 15MOA of windage on the scope you are probably going to have to get the receiver re-drilled if it's that far off. Mine is off by 6 MOA however there is 45MOA of actual adjustment on my Elite so I ended up with 17 right and 28 left. Not great but good enough and not a big deal since I ended up with 42MOA up once I added a 20MOA base.

How much are you in love with the scope and what kind is it that only have 15MOA of adjustability? Leupolds usually have a lot more than 15 (Sounds like it actually has 30 if you were able to adjust 15 one direction). If it did, you would have plenty to compensate.

I believe he means that it TAKES 15moa to zero the wind, NOT that the scope only has 15 moa wind. I aggre, you might have to take it a good smith to see whats out of alignment.

OK. I guess that comment about Luppy stating that he only had 15 threw me. I guess that was the problem they fixed then.

If it continues to be an issue I think the USO rings will allow you to make some windage adjustment, Also Holland's makes a base that will allow you to correct the missalignment,

that's right I still have more windage available, I just don't like the idea of having so much in there, it tells me that something is wrong.

Re: Help with scope mounting?

Thanks guys, I just scraped my idea of getting a picatinny rail, and ordered a long range one piece std leupold base that will have the 20MOA in it, and still allow me to use the windage screws on the base to keep my scope fairly centered up.
