Re: Shim for scope mount?
If still shooting 2" high with scope bottomed out, put .005 under the front, if you want more available elevation and available MOA >6moa put .005 under the rear. I use .005 or .010 shims under the back base until I am within the last 1 to 5 moa adjustment of the scope. Then loosen turret set screws and set to 0. It's nice when you can get them to just within about 2 from the bottom. Then you can crank it all the way down till it bottoms, then back to zero and you are back on 100 yd zero.
I'm sure somebody has the exact calc to answer your question but ballpark .002.
