If it's in as good a shape as you assume, then you shouldn't pass it up. To me, where the 06 stands above the .308, is the ability to handle the larger grain bullets. You were wanting something for larger critters and they just don't get much larger than Moose on this continent anyway. While the .308 can handle them as well as the 30/30 (killed a few with that one myself), the old 06 with a 200 grain pill will flat put the smack down on a Moose. There is a reason the 06 has been the top selling cartridge for a LOT of years. That reason is, it just flat out works.
