My daughter was drawn for the AZ junior elk hunt, which dad is very happy about. However, here is the big question: What rifle would you folks recommend? She's 10 years old and not a "big" 10. She is an excellent shot, but only with a .22, so far. It has to put an elk down in a sportsmanlike and humane way with out making her hate shooting/hunting (and me) forever after, because of teeth jarring recoil. Ideas? I was thinking .243, but everyone I talk to seems to think it's not enough gun for elk. Any opinions would be appreciated.
