I'd check with your PH - one guy I hunted with was obsessed by the record book and wouldn't let me use my 470 on PG because I might miss an opportunity on a bigger animal, even if a tracker was carrying my 300 Mag. It was clearly really important to him so i didn't argue.

He was a great hunter and judge of game and six of my eight PG heads made "the book" for Zambia but, I could have done some of the work as well, or better with the quicker handling, iron sighted 470 and solids.
