Air rifles today can be different to the ones I had in my youth. I borrowed one (to shoot a duckling) and the thing pumped up to very effective pressure. It was damaging the metal paint can I was using to sight it in, through two layers of carpet.

Before anyone takes me up about the duckling. Some bastard had broken its bill trying to catch it. It couldn't eat.
The other eight siblings and two from an earlier clutch survived to fly, and some still come back for a meal sometimes.
