I have the same rifle in .308, with the short stock and 150gr loads the recoil was fairly mild. Mine shoots well under an inch at 100yd with cheap Winchester factory ammo.
My friends boys shoot over 200 rounds of cast bullets, while theses are lighter loads they are only 9 and 11.
If you don't load ,see if you can find some reduced recoil factory loads . If not perhaps pad her jacket with a folded towel.
Rifle fit is the number 1 issue . Ensure she has great ear protection so the muzzle blast isn't the issue.
