Being a retired infantry Marine, all I ask everyone is that if you have children around use locks, vaults, and most importantly....education to teach them about weapons. Respect them..... But, Don't fear them!
As far as air rifles go, they have some really nice ones out now. The "sniper" rifles, and the "scout" rifle come to mind. I've always preferred Crossman, I've had good luck with the Crossman pump that shoots either bb's or pellets. They also increase range and power depending on how many pumps you put on it. Just don't pump over 10 times (pretty sure it's 10 times)or you might blow out the seals in it! My wife's uncle and I used to shoot the heads off wooden matches, that is fun!
Either way good luck, and be Safe! GySgt U
