Welcome back, Phil.
Looking well. Good to read from you again. Interesting results reported on the penetration tests; and the allure of the .30-06.
Everyone realizes that penetration is but one dimension of wounding - placement of entry, direction of the wound in following, and extend of wound, both dimension and strucure/tissue-wise, being the other contributing factors.
So, while in penetration the 06 is on par, something made a world known, white bearded, alaskan guide switch to a .458 Win in a Mauser action. The man went through great length to make this an ultimate rifle for bear guiding - vey utilitarean, if a bit 'ugly'.
How I know? He wrote about it in Rifle magazine.
Thanks, btw, I learned a lot from that article.
