OK inferior in which way? its the Same cartridge, Just a different bullet.
As mentioned in another forum, a 30 06 180gr power point as compared to that of a 150gr power point 270 IS comparable. As the 270 has a Higher sectional density causing it to HAve MOre or as much Knockdown as the 30-06.
If your Constant need for heavier bullets or more selection is not satisfied with that of a cal such as 270 then yes get the30-06.
