If she is realy interested, then have her try out a few guns before you buy. She will know what she can handle. Don't fill her head with horror stories either. She'll start flinching before she ever shoots. My friends son is a 230 pound monster. He has to concentrate on not flinching when shooting a Savage Model 11 in 243. My Eight year old 52 pound son can shoot his NEF youth .243 all day with no problems. He even shoots my Turkey gun. Some people just handle it better. Some guns dispurse recoil better also. I had a Steyr Mountain in .270 that kicked harder than my Remington 721 in 30-06. And i have it tossing a 180gr. NP at 2885fps ( right up there with most factory .300 Win Mags). Don't waist your time on managed recoil. Just get her a gun that fits well and teach her to get it tucked in well.
