I just bought a new Leupold scope 3x9 power. When spinning the dial for zoom from 3 to 9 the dial is super tight. I actually have to use both hands to get it to spin. Is there a way to loosen this or should I just call Leupold to see if it is defective. It is brand new. I've tried spinning it back and forth a bunch to see if it will loosen but it is remaining the same.
