I've owned 2 Leupold scopes and both had this problem. I sent both of them back to have them looked at and they told me nothing was wrong with either of them. I loved the scopes but just coudn't get over this problem. I sold both of them and haven't owned a Leupold product since. I've read this is a common problem with a lot of Leupolds. My Swarovski and Zeiss scopes turn with ease.
