Anyone have scope shiming web links.... 7mm weatherby w/ Redfield mounts and scope not lining up right.... 4' south
I would first check to make sure you have the correct base for your gun, then check your rings to make sure they are a matched set and that the front ring is not taller than the rear. Then I would check to make sure the base is mounted correctly.
If none of that works I would look into a new base and rings and/or a new scope. 4' at 50 yards sounds like a lot of shim material.
Actually, something from .005' to .010' should cover it, but I too, would look for a weak link in the bases or rings first because shimming a scope is a real pita.
lets not assum he doesn't knwo what he's doing an aswer him/her..
Alunium foil is good.. as it's a metel.. use one sheet/strip at a time..., do not wrinkle atall, use 2-3 pieces, but no wrinkle... as you'll vary your shim effectiveness.. sometimes you migth need several sheets..also you can use one or two on the top and the other on the bottom of the other ring.. I have steel Leopold rings on my 6.5-20 x 50mm matt scope, they are Super high rungs, the ring that came with the Ruger wasn't high enough, but even those high priced ring can have flaws, mine did a little.. good enough for hunting, but on a heavy bench rest with good loads.. shooting sometimes 1 inch groups to 2 inch groups at 400 yards.. every LITTLE thing counts..get that scope as strait as pssable.. eleminate errors.. 1 inch groups are hard to get a 4900 yars.. muc much much harder than 0.25 inch at 100 yards, harder than 0.10 at 100 yrds even... you need all the help you can get.. anyone can do it, practice the way you shoot...and the rest is the load and gun.. and thats the hard part.
I have some scope mount stuff on my page:

Okay...first of all, remove the entire set-up and start over. Make sure that when you are mounting the bases, you do so with Loctite. Even fingernail polish will work as thread locker in a pinch. Used it many times. Next, when installing the rings, use a 1" hardwood dowel available at most any hardware/home improvement outlet, to turn the rings into place on Leupold/Redfield style dovetail mounts.
NEVER, FOR ANY REASON, USE THE SCOPE TO TURN IN RINGS ON THIS SET-UP. YOU WILL KILL THE SCOPE.
Then, check the alignment with a little kit available from several supply houses...Cabela's, Brownells, MidwayUSA...for example, that utilizes point-reference units that mount in the rings to determine alignment integrity. You can then respond according to the results. Lapping the rings with the dowel wrapped in 400 Grit Wet-or_Dry paper can solve minor alignment issues.
After getting the rings all lined up nice and straight, mount the scope, Loctite the ring screws, and torque into place. Going from screw to screw, a little at a time in a clock-wise direction until fully tightened.
Bore-sight, <email> fire. If the original issue still exists, and shimming is required, Brownells sells a scope mount shim assortment...
Or do as I do..use my Dremel tool to whack off a few lengths of steel salvaged from an exploded 25' measuring tape. The tape blade is excellent steel, generally. It is already profiled to fit most receiver rings. Drills nicely and is easily hidden under the bases when installed.
