Great looking rifle! The 7mm-08 combo will work well for her. Not sure what recoil pad you have on it but a good one like the Sims Limbsaver will greatly reduce felt recoil. I wouldn't hesitate to drop down to 6.5 caliber with the .260 either with an accu bond or TTSX bullet. In the same model/weight rifle, you should get similar performance to the 7mm-08 with a little less recoil. As others have said, the fit of the rifle and how confident she feels shooting it are most important.
