The 45-70, 30-30, among other old-timers, are made into something they weren't. most folks happily accept the improvements.

Somehow, updating 30-06 performance by running up pressure to equal other cartridges based on the 30-06, brings a lot of negative reaction.

If you want something else that's cool. But to believe the 30-06 has to live at 308 performance levels when it has roughly 30% more case volume than the 308 shows a lack of understanding of internal ballistics.
