I've watched Chub murder a bunch of Alberta mooses with the 120 BT in his 6.5 Blowhole Express.
I have never seen the old fart shoot twice on a moose or a big Northern whitetail with the 120s. They just fall down, most sincerely dead.
Come to think about it, I've never seen him miss. That's a lot more than I can say!!!!
