    Has anyone ever used these to pick up some extra MOA? I know you can get tapered bases, but do these shims work without making the scope too wobbly?

    Shims work great. The amount of pressure between the base and the receiver from torquing down the screws eliminate any movement. You can buy actual shims designed for scope base usage, or you can go field expedient and cut an aluminum soda can.

    I was looking at the ones in the Sinclair catalog. Seems like you've had some success with them. Looks like a good deal when you start pricing out tapered bases!

    Just a cautionary note -

    If you shim a scope base, you create two objects that are parallel but no longer "in-line". To correct this, you can lap the rings after shimming to restore the in-line geometry.

    Minor shimming may not damage a scope tube, but I'd hate to damage a really good optic because I didn't want to buy a tapered base.
