Thread: Scope bell touching the barrel just (sometimes) should I risk it

Shimming is a good idea a coke can shim would be plenty also

Yep, you are onto the key issue.
Watch a slomo of a rifle receiver and barrel flexing under recoil.
You will be surprised how much flex there is.
Having the barrel flexing directly onto the scope at that contact point will
definitely be bad for the scope.
