I don't think you could tell from the dead animals which of the two bullets was used. The important things are that the rifle be CRF, and load be capable of grizz defense.
Good bud killed a 41" cape in Zim last year with his .416 Rigby RSM Ruger. PH carried a PF M-70 .416 Rem; he liked the RSM, but said it was too heavy.
So, from what I hear and read, PH's are less CRF sensitive than many here on the Fire. PF rifles actually do kill stuff...
Evidently, PH liked his lighter weight M-70 PF .416 Rem more than the "better", heavier .416 Rigby, CRF Ruger RSM... Guess he figured he packed it a lot more than he shot it.
And, I'm sure the RSM is a better gun than the PF M-70, costs more for sure.
