For shots within 300 yards, does the 300 win mag offer any advantage over the 30-06?
well if you want to send a 200gn bullet to 300yd as fast or faster than a 180gn 06' , .300mag offers that advantage.
And second, if I do go big game hunting for other animals (i.e., moose, caribou, bear), does the 300 offer any advantage, again, within 300 yards.

If you can shoot a .300 with confidence and don't mind the rifle weight, I don't see a problem.
theres no such thing as being over-gunned.
