No I have not. I did put a set on an X-bolt and they worked good just not enough clearance on the bell so bought a rail and new rings. I have several talleys on various guns and I could most definitely tell a difference between the Leupold and the Talley rings. But sorry I do not own a Weatherby 307 rifle. An for the life of me I cannot remember which rifle has the Leupold Backcountry's. I am thinking they are on my 300Wby in Remington 700 action.
