I would go with the 25-06 because it makes a good varmint rifle as well a a good deer rifle. Less recoil than a .270 and shoots flat.
It should be perfect for the size of animal you will be hunting.
I even met a elk hunter who used a 25-06 with Nosler Partitions.
His family has lived in Colorado for several generations.
He told me " If you put the bullet in the right spot, it doesn't matter what rifle caliber you use. If you don't put the bullet in the right spot it doesn't matter what rifle/bullet you use either."

I like to do my hunting BEFORE I pull the trigger!
There is only one kind of dead, but there are many different kinds of wounded.
