I was hoping Mart would post some moose & grizzly bear photos. I believe he used 165 NP's in a 722.
This cartridge falls into a sweet spot for me: a ton of bite, with but a paltry bark.

I think you're thinking of Waterrat. He has posted pics of dead moose and bear to a 300 Savage in a 722. I'm the 400 Whelen guy. I like the 300 Savage and think highly of it but have not owned one. Yet.
