I have to say that I'm pleased with the complete lack of "What? You let a four year old handle live ammunition?" posts.
What's wrong with a youngster learning about gun safety and ammo storage under the watchful eye of her father? She will develop a lifelong respect for these things and never get herself into a dangerous situation because of it. "Bring up a child in the way they should go, and they will never depart from it" - the Holy Bible.
