I think a 7mm08 will be perfect for her. I started out my daughter with a 7mm08 at the ripe old age of about 11 or 12 years old. Her 1st year she got 2 clean, 1 shot kills on deer. In fact I'm looking around for a 7mm08 for myself. Before she took my 7mm08 I killed the biggest 12 point I've ever killed with it. It was a clean 1 shot kill as well.
