Shims are your friends, Lima. One thing you might want to try is getting some Loctite agent, it's not threadlocker but it's this creepy green stuff that acts like a bedding epoxy. 629 or something. But it will help give you full support of the rear base.
As for the shims themselves, once you've gotten everything down and done a neat job of it, with the rings lapped, you won't have a problem or even notice it is there. I have shims on lots of my toys, it's actually less aggravating than swapping stuff out or chasing parts.

I believe they are talley quick release rings with bases. The bases look like they are in the correct places. This is a pre 64 winchester model 70 action they are on. I bought the gun last week with the scope, rings and bases on it. Shot it yesterday and had this problem so I put a known good trijicon scope on it and this morning had the same issue. Your bases are probably not in the proper orientation. I've never had to shim a pre 64 base.
I try to stick with the basics, they do so well. Nothing fancy mind you, just plain jane will get it done with style. You want to see an animal drop right now? Shoot him in the ear hole. BSA MAGA

Anybody know what number leupold std bases should be correct for a pre 64 model 70? I put some 50023 on and the rear base is about .0035" lower than the front if I put a strait edge a cross them. This is the problem but I need to figure out which ones are correct. Why not use the DD's?

Thanks guys, I ended up shimming the rear base to get the rifle to shoot where it needed to. I still don't like this setup but it is working for now. I wish I could find some bases that would work without shims but no success yet. Stick to golf.

I don't play golf and the bases that are on it now are leupold std bases but thanks for the suggestion.

Really like to see pictures of this setup
Then STFU. The rest of your statement is superflous bullshit with no real bearing on this discussion other than to massage your own ego. Suckin' on my titties like you wanted me.

That's what I was thinking. I put a set of factory-recommended Leupold bases and rings on a standard pre-64 70 two weeks ago and had zero issues. That's with both the Weaver 3-9 Classic initially installed and then with the Leupold 3-9 that's on it now. No issues with bore sighting and final zero-ing with either scope. Both reticles were centered before installation and didn't require but a few clicks to get to final adjustment.
If there's one gun that had holes and dimensions worked out perfectly while in production, and one gun for which every scope mount maker in existence since the beginning of time has worked out the dimensions for its mounts, is the Model 70. If someone is having troubles of this nature I daresay there's a gremlin in the wood pile not caused by the gun or the mounts (if the correctly matched ones were used).

The shim guide says .001" at 100 is 1", .002" is 2", .003" is 3 ", etc.
