Do you know how hard it is just to hit the paper target with a hand gun at a 50feet range? I can get pretty close to the center, which is incredibly hard.
A 9 year old with a snubnose isn't going to hit anything up to 20feet. 
They also trust you with hollow points? If you forget up and hit the ceiling by accident the entire ceiling would start raining metal shards. You don't bring hollow points to shooting ranges.
