I would opt for the Ruger for the obvious reason that bullet selection is very good! The aught six is tough to beat. Now if you had more money "new" would be the way to go but hey when it is tough do what you have to do but choose well-go Ruger. Don't want to get flamed but if you had to choose just one caliber for anywhere in the world the 06 is a good choice and ammo can purchased anywheres. hey were not talking actions right?
