Idahojoe-
Savage action and 6.5 saum is a great combo, but you will be limited with COAL. If you plan to use 130-140 vlds or 140 hybrids then use .081" freebore. If you plan to shoot 140/143 hornady go with .120'" freebore chamber. Using the SA you may only be able to use the .081" chamber. I really enjoy the 6.5 saum chamber, its a fun caliber.
