No such thing as overkill -- shoot what ya WANT to shoot, and enjoy it! I shot a mule deer just shy of 100 yards with a 460. He didn't move 2" after impact. Well, OK, maybe he moved 2" or so SIDEWAYS, but it was still the easiest tracking job I've ever had! And it wasted NO meat at all. Bullet was still going so fast it never had time to expand. Exit hole was almost same size as entrance.

Ya just gotta love big magnums!!! That 475 is going to be my next.

...Wonder what it does to a prairie dog???
