Ok guys need some help. I'm building a savage that will have a heavy varmint 6.5 creed barrel. Will be using a Seekins Precision 20moa base. Should I get the Seekins low (.82) or the medium (.87) rings? The scope is a Vortex Viper PST 6x24x50 FFP.

Will also be using flip caps from vortex or butler creek.
