What height scope rings?

[Rufe]

Hi all, I just purchased a Savage A17 thumbhole target rifle, and plan to put a Bushnell 3x9x40 dawn and dusk scope on it. I looked at a scope height chart and that said low height, but because of the heavy barrel it said it might require a medium. Anyone know the proper answer? I am going to use Weaver rings. Thank You.
