I am working on a horse trade on a model 700 in 30.06.
Blue / synthetic and it has a older Leupold 50 mm scope on it - but the guy says there is a .020 shim under the rear mount... he said he could not get the elevation set right on the rifle.
The mounts appear to be standard Leupold mounts... with the twist and lock mount in the front and the rear mount has the two flat blade screws for locking and windage.
What would cause the need for the shim?
He says he started with the scope in the middle of its adjustment and just ran out of up and down adjustment (could not get the bullet to strike high enough on the paper).
What causes this?
I would not have noticed the shim unless he told me about it...
Please help - this could be my Colorado rifle!!!
