Sounds like you have a good plan for beginners.
At our club, a member bent a stock for the ladies (girls as well) with cast on. We use a handful of H&R single shot 28's.
It was a $20.00 stock change, that really helps with getting the girls on target. Occassional boy too, which is why it wasn't painted.
It's a handy gun to have in the vault. It's clearly marked in yellow.

Out there doing it best I can.
