When I married my wife and she stated hunting I bought her a howa 1500 synthetic stock 270 Win., have the stock cut to fit her with a pachmayr decelerator recoil pad installed. She likes it very well. Later on I got a hold of a ruger 77 mk2 243 Win., she has shot it, likes it, and it fits her well. But she still takes the 270 hunting. The recoil of her 270 with a good recoil pad is much less then in my 270's. Stock and butt pad/ recoil pad makes a big difference in the recoil of a rifle. Have her hold and shoulder some rifles, find the one or one's she likes and that fits her. If possible have her shot some so she can pick the one she likes best. Good luck and happy hunting to you both.
