Just make sure to instruct her, when she's shooting her first rifle, that you want to take the rifle just below the bolt. That's where the rifle's heart is, and you can usually cause the rifle to drop right there, instead of needing to track a wounded rifle through the brush.
Don't you hate it when that happens? They're tough and cagey, too. But I just can't stand that sound they make, especially the bolt actions, so I always go after them. LOL!
