With the 30-06, you can always shoot even heavier if you want, up to 200 gr if you want a bigger hammer. Can't do that with a smaller cartridge.
I have been loading 200 grain partitions and 200 hot cors to 2550 fps for over a decade in the little 308. Many other guys have used this load as well, as its the minimum, bison legal load here in Alaska.
46-47 grains (depending on brass) of alliant mr-2000.
Are you sure that a smaller cartridge cant launch a 200 grainer?
