I'd listen to first response, but either way it seems that since you can't buy it that your dad can't buy it for you(since you can't buy it).
as for going to the range as one example with your father and his guns and being able to handle/shoot them, possibly a different story
my 2cents and pretty much trying to make sense of it...the first response seems to have the meat and potatoes of it all.
all the best
