Late to this party but I think this was conclusively covered in the great book " one man, one rifle, one land" by Y Jones.
Culminating a 25-year hunting career, Jones hunted every North American species and subspecies with his .30-.06 remington 700 with a leupld 3-9 vx 2.
Great book and easy read.

Whaaaat?! A Remington and a Loopy? The trigger didn't freeze? The bolt handle didn't snap off the first time he cycled the action? The scope didn't poop the bed after a few rounds?
I don't believe it
In seriousness though with the mono bullets on the market now is there a reason/purpose for a very heavy loaded 30-06? I know the Partition does a lot of damage through fragmentation/shedding a good chunk of its lead core after impact, but it seems like a 165gr Barnes would be even heavier and with about the same surface area as a heavy 30-06 load.
I mean other than "I like them" which is just fine. But it seems any medium bore cartridge can do the same thing now (if it couldn't before)
