I gotta imagine they would be unless they hold a certain amount of steel above and beyond the bore size in which case the '06 could be .031" larger for stock barrel channel. call them.

They are not always the same. It depends upon model year, brand, etc... The TC ICON uses the same contour for both but Winchester 30-06 barrels are thicker than their 270's as an example.
I prefer the heavier contour given a choice and it is a factor in my selection process.
