what height sig. z ring for a 4-16 Vortex PST?

[encoreguy]

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!

I would think mediums would do it with a rail adding a bit of height.What size is your objective. I have used a rail with highs for a sightron on a savage with a light varmint barrel and regular two piece weaver blocks.
