Look at a Weatherby Camilla and have her hold it and see how it fits, it's designed for females and it absolutely was a game changer for my daughter, I can't hardly hold it but it fits her like a glove!! I'm a huge advocate of getting especially females the right stock and balance to their rifle as it's a game changer and builds confidence right out of the gate!!
I was going to custom build my daughter a rifle till she tried one of these on and I realized I'd just be throwing money away building what already exists, though some day I'm going to have the stock duplicated in nicer wood for her.
