People just need to know how to shoot their damn rifles. And be in shape..
"Run what you brung, take what you won".
Isn't that the damn truth. If a guy can't handle a magnum, use what you can handle. Stay above the minimum required by law and you'll be fine if you put the bullet in the right place.. Elk hunting is (in most cases) more about hunter skill than the rifle or cartridge he uses...
