In case some people missed the picture that UNK posted, she looks like a smaller mammal which might affect gear set up, and what gear actually works.
Also, just a question to ask yourself @UNK. You said it breaks your heart that they qualified marksman. Does she actually care that much to put in the work to get better? Would she actually enjoy being in a rifle class during a weekend vs hanging out with friends? I would be careful about pushing the issue to much at that age if she doesn’t seem interested and try to be supportive in other ways.
