I was in your situation few years back.
I love my 06, already have 270 and wanted something to shoot heavier pills. Using the 06 parent case.
Since I wanted to shoot the heavies, I ended up with 9.3x62.
The 9.3 did scratch my thumper itch, maybe little too much thump until I got limb saver. Anyways, looking back, sometimes I wish I would have had bought a stainless donor T3 , send it to JES and re bore to 338-06 as my original thought.
Lots of bullet selection compared to 35 or 36 cal.
But, I also love the fact my 9.3 can be used on anything

All of them do something better than the 30-06, but none of them do everything as well.
