Phil is probably very busy guiding bear and moose hunters, but I know from our conversations that his penetration tests showed the 220-grain Nosler Partition penetrated deeper than any other .30 caliber bullet he tried--and that included a bunch. I also know that's the bullet he used when folowing up (and stopping) the last wounded brown bear he killed with a .30-06, a few years ago.
He carried the .30-06 because the client he guided shot very well during sight-in--and Phil liked the particular .30-06. Unfortunately, during the actual hunt, the client did not shoot well, and Phil had to follow up the bear (a big one, per usual in his guiding). The 220's worked fine, but Phil expressed some desire for his .458 afterwards.
