The VX3 is what I would get and consider where you use these guns the most. A 06 with either a 1.75-6 for 20-250 yards shooting or a 2.5-8 for say 30-300yards works real well. Better Glass and a sharp clear veiw is better than a larger less focused view.
If your 338 is wearing the 2.5-8 I would get the 1.75-6 for the 30-06 for a more woods friendly rig that can still provide a great veiw at 300 yards.
My dream scope is the VX6 1-6x24mm for my 358win from the muzzle to 300 yards I would be covered. I have never felt under scoped with my VX3 1.5-5x20mm in the field its at the bench I like more magniication. Meaning are my 1.5-1.7" groups realy 1", with my 14 power scope I know, but a 1.7" group will take deer all day long out to 200 yards and more.
