One of my shooting buddies just bought a 6PPC with a Farley action. Serial is 00261. It came with several sets of rings. I don't know what scope is is trying to mount, he removed it from another rifle. After mounting, in an attempt to zero it, he ran out of adjustment and the elevation is all the way down and still not zeroed. Also, the scope is 3/8 of an inch above the front of the barrel. Can anyone who has experience with these actions give me some suggestions.
