Not to jump start the voting on your re-chambering, but first pick for me is the 9.3x62 with 338-06 as second choice due to availability of components. Nothing wrong with a 30-06 spitting out 200-220 grainers as you know, but the 9.3x62 is in a different league.
I hope your medical testing is fruitful.
