She will do just fine with that rifle OK338...
If you folks reload ammo you'll be styling since you can try a swack of different bullets,,, 120 TSX's triple shock and the 100 gr Nosler PT's... Don't count out the 130's and 140's...
She might want to get the stock fitted to her with a soft gel shoulder pad,,, a gel cheek pad/ ammo-over pouch so her eye alines with the optic... I made my own... I shoot Left Hand,,, so the gel pad is on the other side of the stock... Ha
Sport Check had some gel Elbow pads for $20,,, then I got an adjustable ammo pouch to cinch up tight to hold it in place...
It works great for fast draw hunting and shooting sports since I can bump the stock tight to my face to get the shots off...

Lots of fast draw and dry firing this year,,, the cheek pad is a real bouns...
I might knock a 1/2" off my stock for a better fit as well...
Yuppers,,, a nice fitting rifle sure adds to the good times,,, do some planing before changing anything,,, most of us learned this over the years
