Price per shot cheaper than steel? Is that thing reloadable?
Depends on how you measure spending money. When I buy a new gun, the first thing I kill costs the same as the price of the gun. Sure, I overpaid for that one animal but this way the rest are free! That works for boats too! Spend $10,000 on a boat, and your first fish pays it off. Sure, you paid too much for that fish, but the rest are free.
Actually, she could be traded off the kill for a treat and flown again, but for some reason the ducks don't swing around for another look once she's nailed one. Better to have a young bird build confidence and trust than go for seconds.
