What will she be hunting? What will the maximum shooting distance be? What do you consider "light recoil"? What do you mean by reliable?
Do you mean ammo availability or the ability for cleanly taking multiple species efficiently?
I know a smaller framed lady that hunts all sorts of critters year after year and she has shot the same old Remington 700 30'06 for as long as I have known her.
30-30win, .243win, 6mmRem, .257Roberts, 6.5x55swede, .260rem, 7mm08rem,.44remmag, .308win, and the list goes on and on, depending.
