I am mounting a new 4X16 Vortex PST on a Savage 10FP with a one piece base.  The base will be either a Farrell or the Factory one what came with it.  Which size Burris Signature Z-ring should I use Medium or High?  I like the scope as close to the bore as possible, but obviously everything has to clear.  What are your thoughts?
Thanks!
