I was a hunter safety instructor for years where everyone regardless of age had to go through the hunter safety course . I found that the younger they were the easier they were to teach . The older people had a tendancy to think they already knew everything and more of them failed than the younger ones . I have also found that common sense doesn't come with age .
I wasn't aware of any state having a law covering he age you can load and fire a weapon ,only how old you ,must be to hunt .
