My 52D standard barrel, prone model, presently has a Vianni scope mount, but I've run out of elevation to go beyond about 100 yards.  I have a Golden Eagle scope on it.  What are my options to get out to 2-300 yards?  I don't think Mr Vianni makes them anymore, and the EGW website just shows 0 moa bases.  (not willing to drill my gun.  Had it since 1962)  Any info is appreciated.  Thanks........Tommy
