There you are then. The 06' will generally handle a heavier boolit than the 308 better. Their a dead heat up to 165g over that its the 06' . W/hand loading both are capable of much more versatility than what's on the shelf. Gun to gun the 308 has an edge at the end of the day w/its short action and possibly shorter bbl.oz add up after a long pack. You have the 308 already and are familiar w/it so there's bonus points too.
