The truth is a 30-06 is so close to a 7 rem. mag there is no advantage if ya reload. If ya can do it with a 300 win ya can do it with an 06 if the target is a bit closer. I always though neither was needed cause the 06 is right between them. If you need a magnum you need one big enough to make a difference, like a 338 win. Not that I care.
