Far as sights, a scope could get her. We wanna grow the kids not see what they can take. Iron sights could be hard to line up. I'd recommend a simple bead or red dot. Either one is quick and easy.
Now another thing I did was pattern and sight the gun with no kids around.
They only shot light target loads practicing. I used heavyweight 7 or federal Magshot. I'd not be afraid of any load as long as it was forgiving.
Make it too hard and she keeps missing, well she'll prob start not going.
I used mod chokes, eventually as they got older and stronger things changed.
Remember to keep it fun, go at only her pace. She's ready to go home, go home. Keep things fun
