That's my Dad!
I guess he needed an upgrade from that itty bitty .375 for the upcoming deer season.
Actually there's less damage to the meat.
The hole is larger, but the shock to the surrounding meat you find with a smaller rifle is less. We don't get any of the blooded bruised torn meat, it's a clean shot like you've used a great big hole punch. You'd be surprised.
He hasn't had to track a deer for many many years.
