I think you will be fine if she is hitting groups like that. The rage should come in a three pack, shoot at least one and make sure all is good and take the kid hunting. You sound like a dedicated hunter, with that you know you should practice with what ever you use, its a responsibility thing, you know it. Buy a pack of rage, shot one to make sure they are ok, spin test the other two to make sure they are good. If she needs more then two shots on one deer and hunt then you need to rethink the entire thing. Go hunting and have fun! Cam style heads do not take near the energy as rear hinge style.
