I have an old Staghorn Magnum and the rifle you purchased for her replaced mine with some very excellent additions. It has a double lug system and a stiff stock. If it shoots half as good as my old Staghorn, you just remember, you bought it for her.

My Staghorn like 90 grains of powder, and anything you want to stuff down it. I would suggest a 250 grains Shockwave and start her at 80 grains and work it up from there. I think you are going to have a lot of fun with that rifle. And I wish her and you the best of luck.
